Quick Answer: Which animal is the top predator in the tidepool ecosystem?

Dr. Paine’s seminal work, like much of his career, was performed in the rocky tide pools of Washington state. The top predator in these pools is the Pisaster starfish, which feeds mainly on mollusks.

Which organism is the predator in a tide pool?

Land mammals, including humans (Homo sapiens), raccoons (Procyon lotor) and river otters (Lontra canadensis) prey on crabs, fish and shellfish found in tide pools. Sea otters (Enhydra lutris) also scramble among the tide pools to find abalone (Haliotis spp.)

What do tide pool animals eat?

A single tide pool contains many food chains. Algae and other plants are eaten by plant-eating zooplankton; this plankton is eaten by larger, carnivorous plankton; these are eaten by a mussel, barnacle or other marine invertebrate; the mussel is then eaten by an ochre star, which may be eaten by a gull or a sea otter.

What happens when starfish are removed from the ecosystem?

What are tide pool creatures?

Tide pool animals are very well adapted to their ever-changing world of sand and surf. Almost every day of the summer I go to Doheny and search the tide pools for crabs, hermit crabs, limpets, snails, periwinkles, mussels, sea stars, chitons, sea urchins, and what I like to call sea slugs.

What are 5 ways animals use tides?


  • burrowing into the sand (crabs)
  • being covered with thick slime (seaweed and sea-squirts)
  • moving with the falling tide (snails)
  • clamping down onto a rock (limpet)
  • shutting their shells tight (mussels and barnacles).

How do animals survive in tide pools?

As the ocean water retreats at low tide, marine life must withstand hours exposed to the air or in shallow pools. At high tide, animals and plants must survive waves rolling in or crashing down. All must find food and protect themselves from predators.

What do sea anemones eat in tide pools?

Anemones will feed on small fish, snails, limpets, crabs and other marine life. The tentacles of the Anemones are covered with specialized stinging cells called Nematocysts. The Nematocysts will shoot a very small barb connected to the cell by a tiny thread into the prey item.
