Pelecypod
* Most pelecypods feed by filtering organisms from the water.
* lack jaws and radula.

Raw shellfish
* Most raw shellfishes contain bacteria.
* can also transmit infectious diseases to humans
  - carry bacteria

Scaphopod
* are very common in the oceans today.
* have a well-developed foot located at the large end of the shell.

Sea scallop
* are part of sea scallops
* range in color from milky white to slightly pink.

Univalve
* Have only one part to their shell and include animals like snails and abalone.
* are the shells of gastropods.
* can live in the water or outside the water.
* have one shell, and bivalves have two shells.

Abalone
* are also vulnerable to various bacterial and parasitic infections.
* can start to give birth at a small size.
* have tentacles that smell and locate seaweed.
* is an univalve
  - games
  - mollusks
  - shellfishs
  - snails
* live all over the world.
+ Abalone, Description: Gastropods :: Chinese cuisine :: Edible molluscs :: Gastropods :: Seafood
  * Abalones live all over the world. They can be seen along the waters of every continent, except the Atlantic coast of South America, the Caribbean, and the East Coast of the United States. Most abalones are found in cold waters, along the coasts of New Zealand, South Africa and Australia, and Western North America and Japan in the Northern Hemisphere.

Aplacophoran
* are vermiform and spicule-bearing.
* have a radula and a posterior mantle cavity.
* is an univalve

Conch
* Most conchs live in colonies and are found in sand and grassy areas.
* also eat floating organic debris.
* are different colors
  - hermaphrodites that reproduce sexually
  - located in beachs
* eat grasses, algae, and floating organic debris.
* have spiral round shells and are bigger than periwinkles.

### seafood | shellfish | univalve:

Nudibranch
* All nudibranchs are carnivores consuming slow-moving or stationery prey.
* Many nudibranches feed on anemones and hydroids.
* Many nudibranchs can use the poisonous chemicals found in their prey in their own body defence
  - get their bright colors from their prey
  - have gills
* Some nudibranchs actually take in and store some of the coloring substances from the food they eat
  - are solar-powered
  - create their own food by eating coral with algae
* are oval molluscs usually seen crawling very slowly along the seabed
  - very small, averaging less than an inch in length
* can protect themselves from the hydroids and their nematocysts.

  * Frick K. 2003. Predator suites and Flabellinid Nudibranch nematocyst complements in the Gulf of Maine. Proceedings of the American Academy of Underwater Sciences', 22nd Annual Scientific Diving Symposium. The nematocysts wander through the alimentary canal without harming the nudibranch. Then, the cells are brought to specific places on the creature's hind body. Nudibranches can protect themselves from the hydroids and their nematocysts. It is not yet clear how, but special cells with large vacuoles probably play an important role.

Sea hare
* Most sea hares have life.
* Some sea hares discharge a purple inky secretion when irritated.
* are found in sheltered coastal waters, usually where vegetation is thick.
* have a short life
