Urticina piscivora, common names fish-eating anemone and fish-eating urticina, is a northeast Pacific species of sea anemone in the family Actiniidae.
Description
Urticina Piscivora - Fish Eating Anemone - Conservation Syndicate.MP4 - Urticina Piscivora - Fish Eating Anemone.
Urticina piscivora is a large anemone, growing to a maximum height of around 20Â cm (8Â in) and 10Â cm (4Â in) in diameter. The column is bright red in colour. The acontia is absent, but it has tubercles. These are not white and are arranged in circumferential rows. Normally they do not accumulate debris such as shells and sand.
This species may be confused with Urticina crassicornis. Although they may both have a red column, the tentacles of U. crassicornis normally have transverse bands, and olive green blotches are commonly found on the column.
Distribution
This species occurs from Alaska in the north, down to La Jolla, California in the south.
Habitat
Urticina piscivora is almost always found in the subtidal zone. It attaches itself to rocky prominences in locations with a substantial current flowing past.
Diet and behaviour
As its name suggests, this species is capable of capturing and consuming small fishes and shrimp. However, Oxylebius pictus (the painted greenling) and Lebbeus grandimanus (candy stripe shrimp) have the ability to remain among the tentacles without being harmed.
