Calanus glacialis - the biggest copepod of Arctic. The specimens with the length of 0.5 cm are usual. The marine calanoids are filtrators which feed on diatoms.
Nebalia bipes - the specimen of a very interesting order Leptostraca. Leptostracans are the transitional link between very primitive phyllopods and malacostracans (wich contain the most of well-known crustaceans like krill, crabs, shrimps, woodlice e.c.)
Nebalias are not numerous in the White sea.
Diastylis rathkei. This is a Cumacean. Cumaceans are small strange crustaceans which bury themselves in the bottom leaving their pseudorostrum (a small "beak" at the end of carapax) above the surface.
You can see here a small shoal of mysids (Mysis sp.) with luminous eyes.
The only White sea hermit crab - Pagurus pubescens. These crabs reach 7-8 cm in the leg-spread, they are rather big. The only shell suitable for such big specimens is Neptunea.
And this is the only White sea crab - Hyas araneus. Unfourtunately it's dead.
