Quick answer
Starfishs (Asteroidea) are invertebrates found across multiple regions. The five-armed drifter that regrows its limbs. Adults typically weigh roughly 0.5 kg (1 lb), reach speeds of Very slow; centimeters per minute, and live 5–35 years depending on species. They feed on carnivore (mollusks, clams, mussels) and are listed as Least Concern on the IUCN Red List. Ocean floors worldwide, from tide pools and coral reefs to the cold deep sea.

Starfish overview
Starfish (Asteroidea) is a invertebrate listed here as Least Concern. Typical weight about 0.5 kg; lifespan around 5–35 years depending on species.
Starfish ecology
Diet: Carnivore (mollusks, clams, mussels). Habitat: Ocean floors, from tide pools to the deep sea. Movement and social systems reflect those pressures across the native range.
Starfishs and people
Learn before you travel or keep related pets. Wild starfishs are not toys; captive care needs species-specific husbandry.
Status and further reading
Conservation label in our guides: Least Concern. See the full Starfish profile for taxonomy, FAQs, and related topic guides on this site.
Range and habitat
Starfish inhabit Ocean floors worldwide, from tide pools and coral reefs to the cold deep sea. Their preferred habitat includes ocean floors, from tide pools to the deep sea, where they find food, shelter, and breeding sites. Population density varies with prey availability, water access, and human disturbance. Protected areas and intact corridors remain essential for long-term persistence across multiple regions.
Physical characteristics and behaviour
Adult starfish typically measure about 0.25 m in length and weigh roughly 0.5 kg (1 lb). They can sprint at Very slow; centimeters per minute when hunting or escaping predators. Starfishs are known for the five-armed drifter that regrows its limbs — social structure, daily activity, and seasonal movements all reflect pressures in their native environment.
