Epiplegic (surface waters) to ~100 m depth; Nertic (shelves) and over basins; Commonly observed by divers or ROVs, its abundance to and size make it rare to capture in plankton nets; Benthic form has not been observed in the Arctic, suggesting the species may be seasonally imported from the subarctic

Diet includes copepods, larvaceans, other jellies, larger zooplankton and small fish

An obligate benthic phase, that strobulates (buds) to release ephra larvae; larvae mature into adult body-form that releases eggs and sperm; Fertilized eggs settle to seafloor to prooduce a small non-colonial benthic form; Life span in Arctic unknown, possibly only one season

The following is a representative barcode sequence, the centroid of all available sequences for this species.


There is 1 barcode sequence available from BOLD and GenBank.   Below is the sequence of the barcode region Cytochrome oxidase subunit 1 (COI or COX1) from a member of the species.  See the BOLD taxonomy browser for more complete information about this specimen.  Other sequences that do not yet meet barcode criteria may also be available.
