Description

I think this may be eggs of something and seeing as it has the blue it is probably poisonous, like the blue bottle or the sea swallow.

Mind you, it could also be a sea creature!

Description

Just found washed ashore by the tide. It is a swarm of tiny ones, so our first ID was P. utriculus. However we checked on local field guides and on WORMS (http://www.marinespecies.org/aphia.php?p=taxdetails&id=387269) and P. utriculus is now considered the same as P. physalis.

Bad news for our colleague: contrary to P. physalis, P. utriculus is considered not lethal and he's just swam into them... :-)

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...
