The mounds on the genital field are narrowed and approach each other in the caudal end. Genital segment does not carry bumps on the distal or proximal end.
Central Arctic Basin
Oceanic, bathy- to abyssopelagic species. Juveniles found at all depths up to 1000m, adult females below 1400 m.
Female:
Rostrum relatively short, faces down rather than forward. The base of the frontal organ does not protrude much. The back corners of the last thoracic segments protrude slightly and are rounded and pubescent on the bottom edge. The abdomen is 2 times shorter than the cephalothorax, the genital segment widens laterally. The ventral protrusion has a wide base, the genital field is symmetrical, the mounds are narrowed and approach each other in the caudal end. The outer edge of the first segment of the exopodite of P1 is convex and carries a small spine. The outer spine of the second segment of P2 is long, reaches the tip of the next spine. A1 shorter than the cephalothorax.
Male:
unknown
Egg-brooding species. Carry resistant sacs with a strong, highly visible membrane, which contain 5-6 very large brown eggs. Eggs contain enough food stores for all the naupliar stages, and possibly the first 2 copepodite stages (which are presumed not to feed)
Females: 6,30-7,58 mm
Males: 5,65-5,68 mm
Active predators, feed on smaller copepods. Implements a sit-and-wait strategy, staying motionless in the water column, until prey comes into reach, then rapidly jumps towards the prey by movements of the thoracopods and the first antennae and catches the victim with the enlarged maxillipeds.
Paraeuchaeta polaris is een eenoogkreeftjessoort uit de familie van de Euchaetidae.[1] De wetenschappelijke naam van de soort is voor het eerst geldig gepubliceerd in 1950 door Brodsky.
