Peixe-Cachorro, Brazilian Dog Fish ~ Araguaia River, July '10 The Peixe-Cachorro ("Pay-shee Kah-show-hoe") or the "Dog Fish" (also known here in Brazil as the Cachorra, Pirandirá and Paraya) is a fish that can be found in various rivers in Brazil, including the Rio Araguaia, or River of the Macaws. See: According to other sites that i've found in Portuguese (there is hardly any info on this fish, in English) there are actually 2 classes of fish known as the "Dog Fish," the Raphiodon Vulpinus and the Hydrolycus. Within the Hydrolycus class of fish, there are 4 species: The Hydrolycus Scomberoides can be found in the Amazon River and tributaries above the mouth of the Tapajós River. The Hydrolycus Wallacei can be found in the Rio Negro, or Black River, a tributary of the Amazon River; as well as upper basin of the Orinoco River, along the Venezuelan-Brazilian border and in Columbia. The Hydrolycus Armatus and Hydrolycus Tatauaia can be found in the Amazon basin, basins of the Tocantins River, Capim River Essequibo (Guyana) and the Orinoco River basin. This is some confusion in the classification, and the Peixe-Cachorro was initially classified as the Family Characidae, but some scientists contend that it is a unique family: of the same family as the Ramphiodom Cynodontinae, or the Raphiodon Vulpinus. Still others claim that this classification is a sub-family among the Characins. Whatever the class and family, it is known in Brazil as the Peixe-Cachorro, and is quite impressive. The noted differences between the ...

Roof Cleaning | Leaking Roof | Roofing Services | Roof cleaning, most composition roofs will either start to grow moss or algae within a couple years of the roof being installed on your home. The most common cause for roof cleaning is moss growing on the edges or black streaking or mold which is dark in color. In the past this has been resolved by pressure washing the material which will take off the moss or mold along with some roofing material. Moss Mosses can be either dioicous (compare dioecious in seed plants) or monoicous (compare monoecious). In dioicous mosses, both male and female *** organs are borne on different gametophyte plants. In monoicous (also called autoicous) mosses, they are borne on the same plant. In the presence of water, sperm from the antheridia swim to the archegonia and fertilisation occurs, leading to the production of a diploid sporophyte. The sperm of mosses is biflagellate, ie they have two flagellae that aid in propulsion. Since the sperm must swim to the archegonium, fertilisation cannot occur without water. After fertilisation, the immature sporophyte pushes its way out of the archegonial venter. It takes about a quarter to half a year for the sporophyte to mature. The sporophyte body comprises a long stalk, called a seta, and a capsule capped by a cap called the operculum. The capsule and operculum are in turn sheathed by a haploid calyptra which is the remains of the archegonial venter. The calyptra usually falls off when the capsule ...

'The Christmas Tree Worm' The Christmas Tree Worm' (Natural History Episode 5) Christmas tree worms (Spirobranchus giganteus) are an abundant creature on Floridian reefs, making their permanent homes encased inside the limestone skeletons of live coral. Found in a seemingly endless variety of colors and measuring 2-3 cm in diameter, dozens of these worms will typically adorn massive coral heads in local waters. Using only the perception of light and vibration, these animals will retract at lighting speed at the first sense of something ominous approaching. Fortunately the worms come equipped with aa protective double-horned operculum that seals the worm safely inside the inpenetrable coral. A sharp, calcareous spike extends forward of the tube's opening, acting as a further deterant to a would-be predator. The spiraled, 'branchial crown' serves as both breathing and feeding apparatus for the worm, and is the only part of the worm's body that is extended into the water column. The feathery appendages, known radioles, collect plankton that drift by in the current. The radioles are lined with cilia that direct the captured food down the spiral to the worm's mouth.

Coral Grows Faster than Thought 2 Peter 3:4 . . . and saying, 'Where is the promise of His coming? For since the fathers fell asleep, all things continue as they were from the beginning of creation.' Many people know that, despite its appearance, coral is actually a tiny animal. Even a small coral growth may be made up of billions of tiny animals, each living inside its limestone skeleton. What many people don't know is that coral cannot live without the help of algae-a plant. Thousands of one-celled algae live in the tiny stomach of each coral polyp. The polyp requires the waste products of the algae to complete its nutrition requirements and to get the calcium with which it builds reefs. In return, the polyp's stomach provides an ideal protected living place for the algae. Incidentally, the wonderful colors in living coral come from the algae in each polyp's stomach. Evolutionists have said that it must take millions of years for the tiny polyps to build large coral reefs, like the 2000-kilometer-long Great Barrier Reef in Australia. The Great Barrier Reef, incidentally, is considered the largest structure ever built by living organisms. However, it has now been shown that coral polyps can double their own weight in just over 10 days! As a result, the claim of millions of years for the age of the Great Barrier Reef has been reduced by a factor of 40! Many of the long age figures claimed by evolutionists have had to be drastically revised downward as we have learned more about the creation. The ...
Rohu (Labeo rohita) in Perak - Part 1 Rohu (Labeo rohita) is a fish of the carp family Cyprinidae, found commonly in rivers and freshwater lakes in and around the South Asia and South-East Asia. It is a herbivore. In Hindi it is called Rohu.(Rawas is the Indian Salmon, which is quite different) It is called rui in Bengali, rou in Assamese and is popular in Thailand, Pakistan, Bangladesh, Orissa, Uttar Pradesh, West Bengal, Assam, and the Konkan region of India. It is a non-oily/white fish. The roe of rohu is also considered as a delicacy by Bengalis. It is deep fried and served hot as an appetizer as part of a Bengali meal. It is also stuffed inside pointed gourd to make potoler dorma which is a delicacy often prepared to satisfy the palate of the discerning guest. Rohu is also served deep fried in mustard oil, as kalia which is a rich gravy made of concoction of spices and deeply browned onions and tok , where the fish is cooked in a flavorful and tangy sauce made of tamarind and mustard. Rohu is also very popular in Northern India such as in the province of Punjab. It is a speciality of Lahori cuisine as in Lahori fried fish, prepared with batter and spices. It has a body length of 2-3 feet. mouth is present on the ventral side. Teeth are absent in jaws. a single gill opning is present on both sides of the head, which is covered with operculum. Body is covered with scales but in the head region scales are absent The Rohu is also a famed sportfish and gives an adrenaline charged fight, often leaping several ...
Ant Traps Evolutionists Real Science Hydrogen Fuel Tanks Made from Chicken Feathers Could Save $5.5 Million "Multifunctionality and mechanical origins: Ballistic jaw propulsion in trap-jaw ants" Speed record Trap-jaw ants of this genus have the fastest moving predatory appendages within the animal kingdom. One study of Odontomachus bauri recorded peak speeds of between 126--230 kilometres per hour (78--140 mph), with the jaws closing within just 130 microseconds on average. The peak force exerted was in the order of 300 times the body weight of the ant. The ants were also observed to use their jaws as a catapult to eject intruders or fling themselves backwards to escape a threat. A 2008 study of the species Phintella vittatain in Current Biology suggests that female spiders react to the male reflecting ultraviolet B light before mating, a finding that challenges the previously held assumption that animals did not register ultraviolet B light. In recent years it has been discovered that many jumping spiders may have auditory signals as well, with amplified sounds produced by the males sounding like buzzes or drum rolls. Science Fiction Book lungs evolved from book gills. Although they have a similar book-like structure, they are found in different locations. Book gills are found externally while book lungs are found internally. Book gills are still found in horseshoe crabs which have five pairs of them, the flap in front of them ...
DUSKY GROUPER / MERO The dusky grouper is a solitary fish. It likes to live alone in rocks, at depths from the coast to 300 meters, but it's rare to find it below 60 meters. It has a barometric distribution, where the younger specimens are found near the coast and the older ones at the depths. It normally has one cave considered as home and several other caves as temporary refuges. Its home has a minimum of two exits, and a size slightly bigger than the grouper, so no bigger animal can enter in. In case of biting attack or other force to extract it, the grouper opens its mouth, and the operculum spines wedge it inside the cave. It can be found in the Mediterranean, the African west coast and the coast of Brazil. It is rare in the waters of the western Indian ocean, Uruguay, Argentina, north of France and the British Isles.

Scorpion Fish The scorpionfish are a family (Scorpaenidae) of mostly marine fish that includes many of the world's most venomous species. The family is a large one, with hundreds of members. They are widespread in tropical and temperate seas, but mostly found in the Indo-Pacific. They should not be confused with the cabezones, of the genus Scorpaenichthys, which belong to a separate, though related family, Cottidae. Some types, such as the lionfish, are attractive as well as dangerous, and highly desired for aquaria. General characteristics of family members include a compressed body, ridges and/or spines on the head, one or two spines on the operculum, and three to five spines on the preopercle. The dorsal fin will have 11 to 17 spines, often long and separated from each other, and the pectoral fins will be well-developed, with 11 to 25 rays. The spines of the dorsal, ***, and pelvic fins all have venom glands at their bases. Most species are bottom-dwellers that feed on crustaceans and smaller fish, in some cases using the spines to paralyze their victims before gulping them. Others, such as the stonefish, wait in disguise for prey to pass them by before swallowing. Scorpaenid systematics are complicated and unsettled. Fishes of the World recognizes 10 subfamilies with a total of 388 species, while (as of 2006) FishBase follows Eschmeyer and has 3 subfamilies, 25 genera, and 200 species, some of the species being removed to family Sebastidae which other authorities do not follow.

Red Tailed Catfish Red Tailed Catfish The redtail catfish, Phractocephalus hemioliopterus, is a pimelodid (long-whiskered) catfish named for its red or orange caudal fin. In Venezuela it is known as cajaro and in Brazil it is known as pirarara.[1] It is the only extant species of the genus Phractocephalus. This fish originates from South America. Despite reaching a large size, this fish is a common aquarium fish. Extinct Phractocephalus Although the redtail catfish is the only living representative of this genus, there are other members that date back to the upper Miocene. P. nassi was described in 2003, and is from Urumaco, Venezuela. Another undescribed member is known to exist from Acre, Brazil.[1] This genus has a minimum age of about 13.5 million years.[1] Distribution and Habitat The redtail catfish is native to the Amazon, Orinoco, and Essequibo river basins of South America.[1] It is found only in fresh water.[2] This fish has also been introduced into Florida, but it is not established.[2] Anatomy Redtail catfish in an aquarium.The redtail catfish has a broad head with a wide mouth. Its body is primarily dark gray with small darker gray spots. The ventral surface is paler. The redtail catfish has three pairs of long barbels. A lateral white band starts at the caudal peduncle and runs anteriorly, tapering to end anywhere from midway along the body to just behind the operculum. The caudal fin is red or orange, giving the fish its common name. The juveniles may be more intensely ...

Red Lionfish Scorpaenidae, the scorpionfish, are a family of mostly marine fish that includes many of the world's most venomous species. As the name suggests, scorpionfish have a type of "sting" in the form of sharp spines coated with venomous mucus. The family is a large one, with hundreds of members. They are widespread in tropical and temperate seas, but mostly found in the Indo-Pacific. They should not be confused with the cabezones, of the genus Scorpaenichthys, which belong to a separate, though related family, Cottidae. Some types, such as the lionfish, are attractive as well as dangerous, and highly desired for aquaria. In addition to the name scorpionfish, informal names for family members include "firefish", "turkeyfish", "dragonfish", and "stingfish", usually with adjectives added. General characteristics of family members include a compressed body, ridges and/or spines on the head, one or two spines on the operculum, and three to five spines on the preopercle. The dorsal fin will have 11 to 17 spines, often long and separated from each other, and the pectoral fins will be well-developed, with 11 to 25 rays. The spines of the dorsal, ***, and pelvic fins all have venom glands at their bases.[2] Most species are bottom-dwellers that feed on crustaceans and smaller fish. Most species inhabit shallow waters, but a few live as deep as 2200 metres (7200 ft).[1] Most Scorpionfish, such as the stonefish, wait in disguise for prey to pass them by before swallowing, while lionfish ...

The life of Fish Fish Kingdom: Animalia Phylum: Chordata All fish are aquatic and are found in fresh and salt water throughout the world. There are three main classes: the jawless fish (Agnatha), bony fishes (Osteicthyes) and cartilaginous fishes (Chondrichthyes). The jawless fishes, such as lampreys and hagfish, are the only fish that have sucking mouthparts, which makes them dependent on a parasitic way of life. They are primitive fish and fins are either absent or poorly developed. Bony fish possess true ossified, internal skeletons to support the body tissues and a rigid skull of fused dermal bones. Most also have external scales covering the body and a bony flap, the operculum, covering a single gill exit. The spiracle is reduced or lost in bony fishes and the majority have swim bladders evolved from the primitive fish lung. Their eyes are large and of primary sensory importance. The fins are flexible and often able to be folded against the body. This is the biggest class of fish and includes about 20000 species. There are around 900 species of cartilaginous fish. Sharks and rays are two examples that belong to one subclass (Elasmobranchii). These differ from bony fishes in having flexible, cartilaginous skeletons, sometimes strengthened by salt deposits. Elasmobranchs are covered with tooth-like scales called denticles, which helps strengthen the body's structure. They have multiple, uncovered gill exits and they have a good sense of smell. They have long snouts and their jaws are ...

The anterior margin of the pelvic fins and the distal margins of the dorsal, *** and caudal fins are bright blue. Large adults sometimes have a blue ring low on the operculum. Juveniles have dark regions posteriorly on the dorsal, *** and caudal fins. It grows to about 36 cm in length. The Southern Blue Devil is a benthic species that lives in temperate inshore waters, usually on rocky reefs. The species is endemic to Australia, occurring from the central coast of Victoria to south-western Western Australia. It has also been called the Western Blue Devil.
