The hinge ligament hold the two shells together as well as the adductor muscles which controls the opening and closing of the bivalve.
no
PENISES!!!! in my bung hole
they have two shells held together by hinges and strong muscles
No. There are different classes of mollusks. Gastropods (shell-less or single-shelled), Bivalves (2 shells held together by 1 of 2 powerful muscles), and Cephalopods (Small internal shells or no shells at all)
they are called bivalves .(:
They have 2 shells held together by strong muscles.Most remain in one place much of their lives. Most are filter feeders.
They are held together by covalent bonds (they share the electrons in the outer shells, instead of losing or gaining them)
It depends on the type. Some are set and cannot be changed, some are wound up and held with a pin that goes through the hinge to hold the spring.
They are held together by ligaments.
feeder spring
they are not held together.
