Cone shells offshore Louisiana WIlliam Cargile dissects a specimen of the gastropod mollusk Conus ermineus to extract its radula and radular ribbon on board the R/V Pelican, August 2008. The cone shell was dredged in the deep waters offshore Louisiana in the northwestern Gulf of Mexico. The comparative morphology of the radula, the structure composed of rows of many small teeth used for rasping at food and scraping it into the mouth, is important in the taxonomy of cones. Other species of cones seen in this video clip include Conus stimsonii, C. armiger, and an undescribed species. Some shells are covered with epiphytic red algal crusts. Filmed and edited by Suzanne Fredericq in Lafayette LA Cone snails are predatory sea snails that hunt and immobilize prey using a modified radular tooth along with a poison gland containing neurotoxins launched out of its mouth in a harpoon-like action. Cone venom shows great promise as a source of new, medically important substances. This dredging expedition was sponsored by Dr. Cargile and also included other malacologists, and biologists from the University of Louisiana at Lafayette who study the systematics of mollusks, seaweeds and crustaceans.
Aplysia biting When hungry, Aplysia (marine slugs: "sea hare") bite in an effort to find food (eg seaweed). You can see the lips opening and a tongue-like organ (the white thing is called a "radula") come out and try to grab food. Aplysia biting behavior can be conditioned classically and operantly (see ). PS: Yes, I know it totally looks like a ...

Garden Snail (Helix Aspersa) Helix aspersa is a scientific name of a garden snail. They belong to a group of animals with a soft body called molluscs (mollusks). The body of the snail is long, moist and slimy. When the snail is disturbed, it simply withdraws or pulls itself back into its shell to protect its soft body. Do you know where the snail's eyes are ? Yes, the eye is on the tip of the tentacle or at the base of the tentacle for marine species. The snail has two pairs of tentacles on its head. One pair is longer than the other pair. The eyes are on the longer pair. The shorter pair is used for smelling and feeling its way around. What and how does a snail eat ? A snail have something called a radula in its mouth for grinding up its food. This radula is like a rough tongue, which it uses to scrap off leaves and flowers to eat. Snails eat mostly living plants as well as decaying plants. How does the snail move ? The snail moves by creeping on a flat "foot" underneath the body. The band of muscles in the foot contract and expand and this create a kind of rippling movement that pushes the snail forward. The "foot" has a special gland that produces a slimy mucus to make a slippery track. The slime comes out from the front and hardens when it comes into contact with air. Male or female ? The snail is both male and female. Therefore, it can produce sperms and eggs at the same time !However, to fertilize the eggs, the snails need to exchange sperms with each other. An animal which is both a male and a ...

Cuttlefish squids shortfin squids Can you distinguish cuttlefish, squids and broadtail shortfin squids? These molluscs are cephalopods belonging to the order Decapoda, that means they have ten arms. Cuttlefish, squids and shortfin squids show two types of arms: 8 are short and sturdy and present numerous suckers along their inner side. The other two are called tentacles , they are long and thin and bear suckers only at their apex. The two tentacles are not always visible because they are hidden inside a pouch and they come out only during the prey capture. Unlike octopus and curled octopus, suckers have peduncles and are denticulate. Arms surround the mouth which shows two beak-like jaws able to tear off prey tissues. This clip shows the beaks of cuttlefish, squids and shortfin squids. Cuttlefish, squids and shortfin squids possess a radula as most of cephalopods. The radula is a chitinous and denticulate ribbon placed inside the mouth and used to grind food. Now well see the main differences between these molluscs. The body of the cuttlefish is large and pudgy, while it is slender in squids and shortfin squids. In all three animals the mantle surrounding the body shows a pair of flattened structures called fins. However, in cuttlefish, fins are not evident and surround all the body, while, in squids, fins are large and triangular and are present along the distal half of the body. The triangular fins of shortfin squids instead originate near the body posterior extremity. Observing eyes, we notice that ...
Olive Nerite - Mouth Movement This video shows an adult Neritina reclivata in a sal***er tank eating the algae off the glass. This tongue like organ is called a radula, and it is covered with rows of tiny teeth that work like a rough file. As the 'tongue' is slid back and forth across the glass of an aquarium or rocks of it's natural home, it tears off tiny pieces of algae which the snail loves to eat.

tropical abalone in a reef aquarium this is my new tropical abalone i saw at the lfs, and since my tank has more than enough algae to support him, he would be an awesome addition. he is no where near the size of the huge abalones here in southern california thankfully!! you cant see it at this angle, but its shell is black ( with a new ring of green due to its new diet of film algae with another ring of red from eating cyano ) and its radula is also black.
Octopus Beak and Tongue These pictures show the beak and radula of a Pacific giant octopus (Enteroctopus dofleini), including close-up pictures of radula taken under a microscope. The radula is ***agous to a tongue and is used to aid in feeding and rasping through the shells of its prey. This beak and radula came from one of four octopus we found washed up on the beach.

Humboldt squid and beaks My friend HumboldDF collected these Humboldt squid (Dosidicus gigas) beaks for me in 2005 at Shelter Cove, Humboldt County, California. Some unknown guys caught them while fishing. Also shown are a radula, and a pen. The dead one with the shark bites was at Cape Mendocino. These are also known as "flying squid" and "jumbo squid" but they are not "giant squid." They are not named for Humboldt County, but for the Humboldt Current off South America. (Both are named for Humboldt, the naturalist.) The Humboldt squid seem to be showing up farther north and in greater number in recent years -- occasionally in Humboldt County, California too...
