Mollusc Characteristics

References

-Coelomates

-Mantle with a cavity that holds the visceral mass and is responsible for creating the hard shell

-Visceral Mass: includes organs for digestion, reproduction and excretion

-Muscular Foot: usually for movement, used as a sucker, burrowing, jet propulsion

-Radula: used for scraping food and feeding (not in bivalves)

-Gills (Ctenidium): respiratory organ; comb-like structure with cilia to create water current

-Torsion: (especially in gastropods) allows to pull heads into their shell

Species Specifics

Specific Distribution

Habitat

Feeding

Modifications of the Loliginidae Family

-consume 30-60% of body weight daily

-feed on small fish, molluscs, and crustaceans

-use their two tentacles to catch prey

-Found in the Carribean Sea and in Florida

-Live far from land

-Newborns hide under vegetation, usually turtle grass, close to the surface

-Young squid venture deeper to avoid predators

-Adult squid able to go 100m below the water

Special Adaptations

Anatomy and Description

-are able to camouflage (usually to a paler shade)

-flash eye spots and eject ink when in danger

-males create zebra-like patterns to attract females

-stout, broad mantle

-fins that occupy almost the entire mantle

-have a buccal crown without buccal suckers at the mouth

-vary greatly in colour (from greenish to reddish brown)

taken from http://www.thecephalopodpage.org/Ssepioidea.php

-Instead of a muscular foot: 8 arms, 2 tentacles

-Instead of an external shell: Pen/Gladius made of chitin which extends the full length of the mantle

-Advanced eyes with cornea similar to camera lenses

-Gill contains branchial canal (central hole for water flow)

-Mantle contains: stomach,gills, inc sac, reproductive & digestive organs, and pen.

-Strong beak-like mouth to cut open predators and further digest with the radula
