Heteromysis octopodis sp. n.

Of the three new mysid species, this one has the most unique habitat (and partnership).  Scientists discovered. H. octopodis sharing the tidal pool dens of common octopus, Octopus vulgaris. This is the first scientists have documented mysis associating with a cephalopod.

Heteromysis cancelli sp. n.

This species was discovered living shells occupied by the hermit crab, Cancellus macrothrix (hence its name).  This is only the second mysid species known to associate with hermit crabs.

Heteromysis fosteri sp. n.

A striking mysid that grows to about 7mm (0.25″) in length.  It doesn’t share homes with a novel partner, but it does have one outstanding feature: its golden cornea (eyes).  There’s no point resisting calling this the “golden eye mysis.”

These three new mysid species are desribed in ZooKeys.
