Taxonomy of Euphausiidae (http://www.itis.usda.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=95500) from ITIS.
That certain species, particularly many from deep water, have disproportionately large eggs, is explained by the supposition that the young derive the advantage of being hatched in an advanced stage of development.
In the Euphausiidae the digitiform-arborescent branchiae, as if conscious of their own extreme elegance, remain wholly uncovered.
Among many papers that the student will find it necessary to consult may be mentioned the " Challenger " Report on Schizopoda, by Sars, 1885, dealing with the order at large; " British Schizopoda," by Norman Ann.
The Euphausiidae family includes the other 89 known krill species, including one of the most common, Euphausia superba (Dana, 1852), which is the most frequent species associated with krill.
Krill in the Euphausiidae family are shrimp-like crustaceans that swarm in dense shoals, particularly in Antarctic waters.
The bioluminescence of krill species in the Euphausiidae family is a strong blue-green light that may be used for communication to help them congregate and spawn.
