Crossota millsae is a species of deep-sea hydrozoan.[1] Males and females have both been described, and it reproduces sexually. They are viviparous and females brood baby medusae attached to the gastric canals inside the sub-umbrellar space.

Distribution

Crossota millsae was first described from the Pacific Ocean off Hawaii and California.[1] It was subsequently found in the Arctic Ocean[2][3] and in Guayanilla Canyon off Puerto Rico.[4] It lives below 1 km depth in all four regions. Its highest abundance is found at 2500 m off California and 1250 m off Hawaii. In the Arctic Ocean, it has been observed sitting on the seafloor.[5]

Etymology

It was named after Dr. Claudia Mills, a marine scientist at the Friday Harbor Laboratories.
