Not all jellies inhabit the boundless open ocean.
Bell jellies feel more at home in quiet bays and harbors, often near the bottom.
Polyorchis penicillatus has about 100 or more thin, long tentacles, which are used to pick up benthic crustaceans. Captured food is transferred to the mouth, which is attached to a long tubular stomach that extends nearly the length of the bell. Distinctive light-sensitive ocelli, each with a ring of red pigment, are situated at the bases of the tentacles. Long tubular gonads hang from each of the 4 branched radial canals. P. penicillatus can be found in nearshore waters along the entire coast of North America.
