Aspects of Schooling in Euphausia Superba
Journal of Crustacean Biology, 1984ABSTRACT Divers observed schools of Euphausia superba off the South Shetland Islands and in Gerlache Strait near the Antarctic Peninsula. Euphausiids almost always occurred within the confines of dense schools swimming in one direction. Schools formed an infinite variety of shapes but usually were narrow in at least one dimension, so that individuals ...

Peptide hydrolases of Antartic krill, Euphausia superba
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1985Abstract 1. 1. A survey has been made of the peptide hydrolase activities occurring in Antarctic krill, Euphausia superba. 2. 2. A major protein hydrolyzing activity in the pH range of 6–8, and a minor activity at pH 3–4, were detected. 3. 3. Temperature optima of approx.

Larval development of Euphausia nana (Crustacea: Euphausiacea)
Marine Biology, 1984The larvae of Euphausia nana Brinton in Sagami Bay and Suruga Bay, Central Japan, are described and illustrated. The furcilia stage is separated into six stages on the basis of the form of the pleopods and the number of terminal telson spines. Furcilia I, no pleopod or non-setose pleopods and seven terminal telson spines.

Histopathology of Antarctic krill, Euphausia superba, bearing black spots
Journal of Invertebrate Pathology, 2008Small black spots have been noticed on the cephalothorax of Antarctic krill, Euphausia superba, since January, 2001. To study the nature of the black spots, the krill were sampled in the winter of 2003, 2006, and 2007 in the South Georgia region, the Antarctic Ocean.

Collagenolytic serine proteinase from Euphausia superba dana (antarctic krill)
Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 19911. A serine proteinase isolated from E. superba shows collagenolytic properties: it acts on collagens from Achilles tendon (type I and V) and reconstituted fibrils of calf skin collagen under conditions that do not denature the substrates. 2. At 25 degrees C and pH 7.5 the enzyme both splits the calf skin collagen in solution to the fragments TCA and ...
