How long is a starfish's life?
How long do sea stars live? Again, with so many species of sea stars, it's hard to generalize lifespan. On average, they can live 35 years in the wild. In captivity, most live 5-10 years when well cared for.
How old is a starfish?
The fossil record for starfish is ancient, dating back to the Ordovician around 450 million years ago, but it is rather sparse, as starfish tend to disintegrate after death. Only the ossicles and spines of the animal are likely to be preserved, making remains hard to locate.
What is the life cycle of a starfish?
Reproduction and Life Cycle
The sea star spawns by releasing eggs and sperm into the water, where the eggs are fertilized. Females can release up to 2.5 million eggs. Fertilized eggs develop into free-swimming larvae. After about three weeks, the larvae settle and morph into adults.
How long do Ochre sea stars live?
The ochre star can live for 20 years or more, which likely makes it the longest-living sea star in the Pacific Northwest. Sea stars feed on stationary (sessile) or slow-moving species like barnacles, limpets, snails and mussels. Like other sea stars, it everts its stomach to outside its body and around its prey.
