Lophotrochozoans exam Flashcards

A superphylum of invertebrates that includes mollusks, annelids, and flatworms.

A body plan in which the left and right sides of the organism are mirror images.

Organisms in which the mouth is the first cavity formed during embryonic development.

Larvae characterized by a ring of cilia used for movement and feeding.

A specialized structure used for suspension feeding in some Lophotrochozoans.

Foot, visceral mass, and mantle.

A class of mollusks that includes snails and slugs.

Mollusks with bodies enclosed within two shells, such as clams and oysters.

Marine predators like squid and octopuses, known for their tentacles and advanced nervous systems.

A feeding structure that functions like a rasp to break down food.

Mollusks with a shell made up of eight dorsal plates.

To cover the visceral mass and often form a hardened shell.

Acoelomate organisms with a rudimentary digestive system and no gas exchange organs.

Microscopic organisms with bilateral symmetry and a ring of cilia around their mouths.

A form of asexual reproduction where females produce unfertilized eggs that develop into more females.

Mostly freshwater ecosystems.

Segmented worms like earthworms and leeches, which are coelomates.

A type of annelid with parapodia and chaetae for movement.

A subclass of annelids that includes earthworms and leeches.

To eject water for jet propulsion.

Coral reef-building animals that look like moss and are also known as Bryozoans.

Marine animals with a pedicle used to anchor themselves, having a top and bottom shell.

A digestive tube with two openings, a mouth and an anus.

Diffusion across their body surface.

A cavity filled with hemolymph that bathes the organs directly.

Suspension feeding by trapping food particles in their gills.

Larvae with a ring of cilia for swimming and feeding.

Animals with a lophophore for suspension feeding.
