Complete mitochondrial genome of Antarctic krill Euphausia superba (Eucarida: Euphausiacea) [PDF]
Mitochondrial DNA Part B: Resources, 2017 Antarctic krill Euphausia superba is a very important species in Antarctic ecosystem. The mitochondrial genome of E. superba was completed with 16,591 bp in length, gene arrangement and order was the same as previous studies. The overall A + T content is

Cloning and Characterization of Chitin Deacetylase from Euphausia superba. [PDF]
Int J Mol SciChitin deacetylase (CDA) can catalyze the deacetylation of chitin to produce chitosan. In this study, we identified and characterized a chitin deacetylase gene from Euphausia superba (EsCDA-9k), and a soluble recombinant protein chitin deacetylase from Euphausia superba of molecular weight 45 kDa was cloned, expressed, and purified.

The opsin repertoire of the Antarctic krill Euphausia superba [PDF]
Marine Genomics, 2016 The Antarctic krill Euphausia superba experiences almost all marine photic environments throughout its life cycle. Antarctic krill eggs hatch in the aphotic zone up to 1000m depth and larvae develop on their way to the ocean surface (development ascent) and are exposed to different quality (wavelength) and quantity (irradiance) of light.

Hydrodynamics of the fast-start caridoid escape response in Antarctic krill, Euphausia superba [PDF]
Scientific Reports, 2023 Krill are shrimp-like crustaceans with a high degree of mobility and variety of documented swimming behaviors. The caridoid escape response, a fast-start mechanism unique to crustaceans, occurs when the animal performs a series of rapid abdominal ...
