How does the moon jellyfish move forward?
Using tentacles to sweep the water

What are the other organs associated with muscles to help scallops swim?
Tentacles and hinge
Valves and hinge
Labial palp and hinge
Cerebral ganglia and valves
The first muscle is called (a) . It is a dominant part of the scallop body, which is mostly cooked for seafood.
Phasic adductor consists of the thick filaments called ____ and thin filaments called_____, which both filaments perform a sliding mechanism to create the movement.
(a)
The contraction of the phasic adductor _____ the hinge ligament, and the valve ____, which expels water out of the mantle cavity through jets on either side of the hinge. When the phasic adductor relaxes, the hinge ligament is _________. Then, the valve _____, which allows the subsequent contractions of the phasic adductor muscle to create more jets.
