Ecology & Habitat

Habitat

Rocky intertidal zones and subtidal areas along the North American Pacific coast, typically at depths between 0-50 meters, often attached to rocky substrates in cold, nutrient-rich marine environments.

Ecological Role

Key component of marine benthic ecosystems, providing habitat and shelter for small marine organisms, and serving as a predator in the marine food web by capturing planktonic prey using venomous tentacles.

Morphology

  • SKIN COAT Thick, leathery epidermis with red to reddish-orange coloration, containing symbiotic zooxanthellae
  • LIMBS WINGS Multiple hollow tentacles used for prey capture and defense, each tentacle containing specialized stinging cells (nematocysts)
  • HEAD SENSORY Radial symmetry with multiple sensory receptors around oral disc, capable of detecting chemical and mechanical stimuli
  • BODY STRUCTURE Columnar body with numerous retractable tentacles arranged in multiple rings, diameter ranges 5-20 cm, height 10-30 cm, robust muscular wall with distinctive crusty external texture
