Common Fjord Sea Star

Cosmasterias lurida

Cosmasterias lurida, commonly known as the Common Fjord Sea Star, is a benthic species that inhabits solid substrates such as rocks, cobbles, and boulders. This sea star can be found in a range of environments from intertidal zones down to depths of 650 meters. Its distribution spans the Southeast Pacific, Southwest Atlantic, and the Atlantic Antarctic, thriving in subtropical to polar climates. Divers may encounter this species at various dive sites, as it has been recorded near DiveSight dive sites. The Common Fjord Sea Star exhibits both asexual and sexual reproduction methods. It can regenerate lost limbs and also reproduce sexually, with embryos developing into planktonic larvae before metamorphosing into juvenile sea stars with distinct stubby arms. This life cycle allows for a wide dispersal of the species, contributing to its presence in diverse habitats. When diving, encounters with the Common Fjord Sea Star can be quite common due to its widespread distribution. It is generally found resting on the seafloor, where it blends in with its rocky surroundings. Divers should take care to observe its behavior without disturbing its habitat. The species is currently not evaluated by the IUCN, indicating a lack of specific conservation status assessment.
