Fish-Eating Anemone

Fish-Eating Anemone

Urticina piscivora

Physical Description

Fish-eating anemones (Urticina piscivora) are large, cylindrical invertebrates with a diameter ranging from 5 to 30 centimeters. They have a muscular column topped with a ring of tentacles, often colored in shades of red, orange, or brown.

Habitat and Geographical Range

Fish-eating anemones are typically found in the cold waters of the North Pacific Ocean, along the coasts of Alaska, Canada, and the northern United States. They inhabit rocky substrates in intertidal zones and can also be found in deeper waters.

Diet and Reproduction

As their name suggests, fish-eating anemones primarily feed on small fish and crustaceans. They capture prey using their tentacles, which are armed with stinging cells called nematocysts. Reproduction usually occurs through external fertilization, where eggs and sperm are released into the water column, resulting in the development of larvae.

Physical Threat to Humans

While fish-eating anemones are not aggressive towards humans, they possess venomous nematocysts in their tentacles that can cause irritation or allergic reactions if touched. It’s advisable to avoid direct contact with these creatures to prevent any potential discomfort.
