Nephrostome

A

the funnel-like component of a metanephridium which push the water, metabolic wastes, unnecessary hormones and other substances into the metanephridium.

33
Q

Radula

A straplike scraping organ used by many molluscs during feeding.

34
Q

Mantle

One of the three main parts of a mollusc; a fold of tissue that drapes over the mollusc’s visceral mass and may secrete a shell.

35
Q

Shell

A

hard surface that covers the outer surface of an organism

Univalve

A

having one valve or shell.

40

41
Q

Operculum

A

a protective bony flap that covers and protects the gills.

A

the oldest part of the shell that resembles a large hump on the anterior end of the dorsal side of each valve.

43
Q

Hinge

A

Ligament that joins two separate shells, or valves.

44
Q

Filter feeders

A

Filter feeders are animals that get their food by moving water through a structure that acts as a sieve.

45
Q

Incurrent siphon

A

Usually water enters the mantle cavity through the inhalant siphon, moves over the gills.

46
Q

Excurrent siphon

A

Water exits the mantle cavity through the excurrent siphon.
