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.

AKA Brown Bushy Hydroid or California Stick Hydroid as per Lamb & Hanby, p. 99. Alternating branches with visible polyps (that's what this Dendronotus frondosus is munching). Found on dock.

Description

Jellyfish floating at the surface. Light-orange in colour. Long thin strands floating out from it. A 'ruffled' look to the main bulk of its tissue. Can someone ID it for me?

Description from Wikipedia

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...
