centipiede @ One Tree Hill..MATHERAN=--bHARAT cHHATRE One Tree Hill-MATHERAN trek wid HimSahyadri Trekkers 13th jul 08 ABT DA cENTIPEDES Centipedes Fossil range: Silurian - Recent Scientific classification Kingdom: Animalia Phylum: Arthropoda Subphylum: Myriapoda Class: Chilopoda Centipedes (from Latin prefix centi-, "hundred", and Greek ποδός podos, "foot") are arthropods belonging to the class Chilopoda and the Subphylum Myriapoda. They are elongated metameric animals with one pair of legs per body segment. A key trait uniting this group is a pair of poison claws or forcipules formed from a modified first appendage. This also means that centipedes are an exclusively predatory taxon, which is uncommon. Centipedes normally have a drab coloration combining shades of brown and red. Cavernicolous and subterranean species may lack pigmentation and many tropical Scolopendromorphs have bright aposematic colors. Size can range from a few millimeters in the smaller Lithobiomorphs and Geophilomorphs to about 30 cm. in the largest Scolopendromorphs. Worldwide there are estimated to be 8000 species . Currently there are about 3000 described species. Geographically, centipedes have a wide range, which reaches beyond the Arctic Circle . Centipedes are found in an array of terrestrial habitats from tropical rainforests to deserts. Within these habitats centipedes require a moist micro-habitat due to their rapid rates of water loss. Accordingly, they are found in soil and leaf litter, under stones and deadwood, and inside logs. In ...

WORM SNAKES-Brahminy/Common Worm Snake (Ramphotyphlops braminus) There are 14 species of worm snakes, all of which belong to the genus Typhlina. It is easy to mistake most of them for worms, until you see the shiny eyes and minute shiny scales. The commonest one is reddish brown and found throughout India. Scientists were startled to find that they could locate males in this genus and discovered that worm snakes are "parthenogenic". That is, a female can fertilize her own 5 to 8 eggs without the help of a male. Worm snakes are found in moist, wet earth or under leaves. They feed on worms and maggots, which they hunt underground. When handled, like burrowers, these snakes poke with their tails in defence. This gives people the idea that they are stinging with their tails-which of course no snake is capable of doing. Brahminy/Common Worm Snake (Ramphotyphlops braminus)- Kingdom: Animalia Phylum: Chordata Subphylum: Vertebrata Class: Reptilia Order: Squamata Suborder: Serpentes Family: Typhlopidae Genus: Ramphotyphlops Species: R. braminus Binomial classification: Ramphotyphlops braminus general length between 6.35-16.5 cm (2½ to 6½ inches) in length. Venom Toxicity: No venom or means to inject it. Beaked Worm Snake (Grypotyphlops acutus) - general length of the Beaked worm snake is about 600mm ie 60cm. Its the longest of all worm snakes in our country. Ramphotyphlops braminus is a harmless blind snake species found mostly in Africa and Asia, but has been introduced in many other parts of the world.

Marc Kirschner (Harvard U) Part 1 The Origin of the Vertebrate Nervous System Modern cell and developmental biology has a lot to contribute to our understanding of the deep history of animal origins, which until recently has been largely the province of paleontology. In this set of lectures, I hope to show how recent studies by a very small group of scientists on a virtually unknown phylum of marine organisms, the hemichordates, has helped explain some of the major mysteries of the origin of vertebrates. This is a tour of not only vertebrate origins but the contribution that modern molecular and genomic tools are making to developmental biology. In the Introduction: Vertebrate body plans and the odd phylum of Hemichordates, I discuss the largely anatomical features that we use to identify the Vertebrates as a Subphylum or the chordates as a Phylum. These include such commonly perceived anatomical features, as the blocks of muscle around our trunk, called somites and tail. I also discuss some less obvious features, such as the notochord, a cartilaginous rod found in fish and found at least embryologically in every vertebrate. How did these originate from simpler organisms? I introduce a primitive related phylum, the hemichordates, and a particular animal, the acorn worm. In Part 1: The origin of the vertebrate nervous system: the Hemichordate perspective, I discuss why vertebrates ended up with a centralized nervous system that is highly organized from head to tail. It is surprising that the acorn worm has many of the patterning features of the ...

Amblypigids Amblypygi is an order of invertebrate animals belonging to the class Arachnids, in the subphylum Chelicerata of the phylum Arthropods. Amblypygids are also known as whip spiders and tailless whip scorpions (not to be confused with whip scorpions that belong to the Arachnid order Thelyphonida). The name "amblypygid" means "blunt rump", a reference to a lack of the telson ("tail") carried by related species. As of 2002, approximately 5 families, 17 genera and 136 species have been described. They are found in tropical and subtropical regions worldwide. Some species are subterranean; many are nocturnal. During the day, they may hide under logs, bark, stones, or leaves. They prefer a humid environment. Amblypygi are not true spiders or true scorpions, but a distinct arachnid order.

Various Sea Jellyfish Jellyfish (also known as jellies or sea jellies or medusozoa) are free-swimming members of the phylum Cnidaria. Jellyfish have several different morphologies that represent several different cnidarian classes including the Scyphozoa (over 200 species), Staurozoa (about 50 species), Cubozoa (about 20 species), and Hydrozoa (about 1000--1500 species that make jellyfish and many more that do not). The jellyfish in these groups are also called, respectively, scyphomedusae, stauromedusae, cubomedusae, and hydromedusae. All jellyfish are embodied in the Medusozoa subphylum. Medusa is another word for jellyfish, and as such is used to refer specifically to the adult stage of the life cycle. Jellyfish are found in every ocean, from the surface to the deep sea. Some hydrozoan jellyfish, or hydromedusae, are also found in fresh water; freshwater species are less than an inch (25 mm) in diameter, are colorless and do not sting. Many of the best-known jellyfish, such as Aurelia, are scyphomedusae. These are the large, often colorful, jellyfish that are common in coastal zones worldwide.

Sri Lanka,ශ්රී ලංකා,Ceylon,Myriapoda,Mille pattes,Tausendfuessler, Myriapoda is a subphylum of arthropods containing millipedes, centipedes, and others. The group contains 13000 species, all of which are terrestrial. Although their name suggests they have myriad (10000) legs, myriapods range from having over 750 legs (Illacme plenipes) to having fewer than ten legs. The fossil record of myriapods reaches back into the late Silurian, although molecular evidence suggests a diversification in the Cambrian Period, and Cambrian fossils exist which resemble myriapods. The scientific study of myriapods is myriapodology. (Wikipedia)

King Crabs - Classification and Evolution Part 1 This video is about the taxonomy and evolution of king crabs, family Lithodidae. These crustaceans are fascinating, as they are actually not related to the true crabs (like Dungeness crab, blue crab, snow crab, etc) but are highly modified hermit crabs. In the north Pacific we have 19 species of king crab. It is thought that this family evolved in the north Pacific. With the exception of two (which are credited) all of the photos and video clips used are mine.

Barnacle A type of marine arthropod belonging to the infraclass Cirripedia in the subphylum Crustacea, the barnacle is related to crabs and lobsters. Free-swimming as larvae; as adults they form a hard shell and live attached to surfaces. Barnacles are found exclusively in marine environments and tend to live in shallow tidal waters. Barnacles eat plankton and detritus that they pull out of the surrounding water with their feathery food-catching appendages. As a result of their fixed position as adults, to facilitate genetic transfer between isolated individuals, barnacles have extraordinarily long penises. In fact, barnacles have the largest penis to body size ratio in the animal kingdom. --- Music by Andrew Bird (Album: Armchair Apocrypha - Song: Armchairs)

Purple Martin Roost at Main St & Hendry St in Downtown Fort Myers Purple Martins flying at dusk just prior to roosting for the evening at the southwest corner of the intersection of Main & Hendry streets in downtown Fort Myers, FL. (7/25/09) Purple Martins (Progne subis) are the largest member of the swallow family in North America, measuring 7 1/2 inches long and weighing 1.9 ounces. Taxonomically they are placed in the Kingdom: Animalia; Phylum: Chordata; Subphylum: Vertebrata; Class: Aves; Order: Passeriformes; and Family: Hirundinidae. Three races (subspecies) are recognized: Progne subis subis breeding in eastern North America and eastern Mexico; Progne subis hesperia breeding in the deserts of Arizona, western Mexico, and Baja California; and Progne subis arboricola breeding along the Pacific coast of the United States and Canada, and in the Rocky Mountains. Purple Martins spend the non-breeding season in Brazil then migrate to North America to nest. East of the Rockies they are totally dependent on human-supplied housing. West of the Rockies and in the deserts they largely nest in their ancestral ways, in abandoned woodpecker nest cavities. In the Pacific northwest, Martins are beginning to use gourds and clusters of single-unit boxes for nesting. The pair-bond of the Purple Martin is monogamous. The male and female cooperate equally in building the nest out of mud, grass and twigs. The female lays two to seven pure-white eggs at a rate of one egg per day. The female incubates the clutch for approximately fif*** ...
