What happens if there are no starfish?

Sea otters eat them too. The sea star die-off may indirectly help otters by increasing the availability of high-fat, high-protein sea urchins. When sea stars die, urchins come out of hiding and overgraze on kelp, creating a shortage of food and habitat for otters, fish, and other marine life.

What would happen if starfish species were removed from the ecosystem?

A keystone species has a very large effect on an ecosystem. For example: seas tars prey on mussels and if the sea stars are removed from the environment, the mussel population will greatly increase and other organisms may have difficulty living in that environment.

What role do starfish play in the ecosystem?

What threatens a starfish?

Global warming is likely a major cause of the disease, causing a heat wave in the oceans. Warmer temperatures exacerbate sea star wasting disease, allowing it to kill faster and have a bigger impact, said Harvell, author of the forthcoming book “Ocean Outbreak, Confronting the Rising Tide of Marine Disease.”
