Yes, they are truly coelomic.
A body space or cavity in a mollusk is called a coelom. It is a fluid-filled cavity that surrounds the internal organs and provides support as well as a space for organ movement.
I came here to get help, cause I'm a sophmore in hs and i need help on how to answer that Q. I'm really sorry, but i also need that Q.
Coelom. It is partitioned by septa, which is a divider between segments of the worm.
Mollusks are soft-bodied invertebrates with a muscular foot, a head, and a mantle that may secrete a protective shell. They also have a radula for feeding and a coelom for internal organs. Mollusks exhibit a wide range of shell shapes and sizes, and include animals like snails, clams, octopuses, and squids.
No, a turtle is a reptile.
no a bee isn't a mollusk.
Frogs have a coelom, a body cavity that houses their internal organs. Organs found in a frog's coelom include the heart, lungs, liver, stomach, and intestines. The coelom provides a space for these organs to function and enables flexibility in movement.
It was appeared in nematodes.Annelides had first true coelom.
No, a flatworm does not have a body coelom.
A rock is not a mollusk
As protostome phyla evolve, the coelom may change in structure and function. For example, in some phyla like annelids, the coelom functions as a hydrostatic skeleton. In arthropods, the coelom may be reduced or lost altogether.
yes an scallop is a mollusk
