Description

No idea what this is. It was hard, felt rough and calcified like coral. Not at all soft like sponge or tunicate, and tiny 'polyps' with dark centers and 'hairs' are visible. About 1" across and 1/2" high. Growing among tunicates on the underside of a float at the dock. Perhaps something introduced?

Description

This appears to be a colony of Lafoea dumosa or Muff Hydroid, as it's similar to the photo and description on p.103 of Lamb & Hanby. It was growing on the dock with barnacles, just a few inches underwater. The hydroids looked to be up to 4" long.

Cnidaria (/naɪˈdɛəriə/ with a silent c) is a phylum containing over 10,000species of animals found exclusively in aquatic and mostly marine environments. Their distinguishing feature is cnidocytes, specialized cells that they use mainly for capturing prey. Their bodies consist of mesoglea, a non-living jelly-like substance, sandwiched between two layers of epithelium that are mostly one cell thick. They have two basic body forms: swimming medusae and sessile polyps, both of which are radially symmetrical with mouths...
