A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as ...
A depiction of an Arctic marine food web. The phytoplankton, the base of the food web, are able to grow due to the polynya in the sea ice above them. In general, polynyas tend to be more biologically productive as a result of containing more phytoplankton than the surrounding water. [16]
Pandalus borealis is a species of caridean shrimp found in cold parts of the northern Atlantic and northern Pacific Oceans, [1] although the latter population now often is regarded as a separate species, P. eous. [2] The Food and Agriculture Organization refers to them as the northern prawn. Other common names include pink shrimp, deepwater ...
Ringed seal. The ringed seal (Pusa hispida) is an earless seal inhabiting the Arctic and sub-Arctic regions. The ringed seal is a relatively small seal, rarely greater than 1.5 metres (5 ft) in length, with a distinctive patterning of dark spots surrounded by light gray rings, hence its common name. It is the most abundant and wide-ranging ice ...
