Phylum • Sea Anemones are Cnidarians • They have stinging tentacles • They live in the benthic zone of the ocean • They are related to corals, jellyfish, tubedwelling anemones, and hydra.

Habitat • Sea Anemones spend most of their attached to rocks on the sea bottom or on coral reefs waiting for fish to pass close enough to get ensnared in their venom-filled tentacles

characteristics • Their bodies are composed of an adhesive pedal disc. • Sea anemones remain polyps for their entire adult life, they never transform into the medusa form as jellyfish do. • The mouth, also the anus of the sea anemone, is in the middle of the oral disc surrounded by tentacles armed with many cnidocytes

Why is it important • Sea anemones are important to the ecosystem. • Keep fish protected from predators • They give fish their habitat • They also trap the harmful fish with their tentacles.

Current Issues • They live on coral reefs and the coral reefs are dying because of the environment, • Global warming, and the warmness of the water. • Which can cause water quality issues that will quickly effect the anemone.

What it eats • The sea anemone eats small fish and shrimp. • They also eat plankton, isopods, and amphipods

How it Reproduces • Both sea anemones can reproduce sexual and asexual. • In sexual reproduction males release sperm to stimulate females to release eggs, and fertilization occurs. • Anemones can also reproduce asexually, by budding, binary fission, and pedal laceration, in which small pieces of the pedal disc break off and regenerate into small anemones.
