In New York City, they're repopulating the harbor with farmed oysters to build reefs with the bivalves that stop the kind of erosion that made Hurricane Sandy so destructive while filtering toxins out of the water.

“No cephalopods were chewed in the making of this film"

The introverted rostrum of the Pectinibranch Gastropods presents in contrast to these a limited range of movement.

The rest of the body consists of the foot ventrally and the visceral mass dorsally.

The mantle of mollusks and brachiopods secretes the shell in species that possess shells.

Water enters the mantle cavity on the outside of the gills, and the entrance of the mantle cavity closes.

The radular teeth are of several different kinds in each transverse row.

In some vertebrates, for example the chicken, the ganglion cell axons are myelinated inside the retina.

The pallial cavity, with its organs, is by this torsion moved up the right side of the larva to the dorsal surface, and thus the left organs become right and vice versa.

Green hemolymph oozed out, working its way slowly down the side rail of the dilapidated ladder, its pungent odor thick in the air.

During the struggle the fly ruptured her alimentary tract, which allowed some of the flagellates in the gut to leak into the hemocoel.

Its food consists of microscopic organisms which are taken in through the incurrent siphon.

Wastes exit through the excurrent siphon.

He looked exceptionally green around the gills when an unsympathetic cameraman pulled up beside him earlier this afternoon

These small palps were probably retractile, and capable of being withdrawn entirely under the hood.

The result is very tense adductor muscles.

The pyrenoid is evidently concerned in the formation of the chromatophore, or in its division

"It continues to grow with a dome shape, but it can be sessile or pedunculated."
