Astarte borealis is a species of bivalve mollusk in the family Astartidae. This marine species is found in the cold waters of the Arctic Ocean and the northern parts of the Atlantic Ocean and Pacific Ocean.

Description

Astarte borealis has a thick, robust shell that is typically oval or triangular in shape. The shell surface is often smooth, with concentric growth lines. The coloration of the shell can vary, but it is usually a shade of brown or gray. The interior of the shell is often white or light-colored.

Habitat

Astarte borealis is commonly found in sandy or muddy substrates in cold marine environments. It is adapted to live in the benthic zone, often at depths ranging from shallow waters to several hundred meters.

Distribution

This species is distributed across the northern hemisphere, particularly in the Arctic regions. It is found in the waters surrounding Greenland, Canada, Russia, and northern parts of Europe and Asia.

Ecology

Astarte borealis is a filter feeder, primarily consuming plankton and organic particles suspended in the water. It plays a role in the marine ecosystem by contributing to the benthic community structure and serving as prey for various predators, including fish and seabirds.

Reproduction

The reproductive cycle of Astarte borealis involves the release of eggs and sperm into the water column, where fertilization occurs. The larvae are planktonic and undergo several developmental stages before settling to the seafloor and metamorphosing into juvenile bivalves.

Conservation

Currently, there are no major conservation concerns for Astarte borealis. However, like many marine species, it could be affected by changes in ocean conditions, such as temperature fluctuations and pollution.
