Thysanoessa raschii explained

Thysanoessa raschii, sometimes known as Arctic krill, is one of the most common euphausiid species of the subarctic and Arctic seas. They may reach 20mm25mm long, and are sexually mature above 14mm.[1]

T. raschii is a major prey item of several taxa, planktivorous fishes and marine mammals. It is also a common prey item of seabirds, including shearwaters.[2]

This species goes through a number of stages in its development. Roderick Macdonald defined the characteristics of fourteen stages, or 'furcilia'.[3]
