Benthocodon hyalinus
provided by wikipedia EN
Benthocodon is a genus of hydrozoans of the family Rhopalonematidae.[1] The genus contains two known species: Benthocodon hyalinus[2] and Benthocodon pedunculatus,[3] however due to the small size and red pigmentation, they can easily be confused with related genera.[4] Unlike many hydromedusae, these jellyfish do not have a sessile stage. Rather, they spend their entire lives in the water column as plankton. The genus Benthocodon can be found near the sea floor in the Pacific Ocean from Antarctica to California[5] to the Arctic Ocean.[6]

Description
provided by World Register of Marine Species
Peduncle¼ or more the length of the manubrium; eight linear to sinuous gonads attached along most of the radial canals becoming pendant distally; lacks pigmentation on the subumbrella, and the gonads extend along most of the length of the radial canals, only at their distal ends are the 8 linear gonads pendant; more than 800 tentacles of di?erent sizes but one type. Reaches up to 4 cm in diameter and has been observed in moderately dense aggregations just above the bottom.
