Krill

A krill has interior legs and in one side of each leg are thorny hairs.
And the thorny hairs of left and right legs are engaged with each other, making a funnel-shape net. Krills eat only very small plant plankton,filtering sea water thorough this net. A Krill has exterior gills, gaksae, on its chest legs. It fully matures about 2 years after hatching and grows up larger in summer, ending up with the food of finbacks, fish, squids and sea birds circulating around the Antarctic.
