GIANT GREEN ANEMONE (Anthopleura xanthogrammica) © Jens Troeger
Giant Green Anemone, is a species of intertidal sea anemones, of the family Actiniidae. Other common names: Green Surf Anemone, Giant Green Sea anemone, Green Anemone, Giant Tidepool Anemone, Solitary Anemone, and Rough Anemone
- The crown of tentacles can be as wide as 10” or 25 cm in diameter, while the column, itself, tends to be widest at the base in order to offer a more stable connection to the rocks.
- It has a broad, flat oral disk surface and no striping, banding, or other markings
- Submerged in sunlight, A. xanthogrammica can appear bright green.
- When not submerged, it appears dark green or brown.
- This is because the anemone tends to close up and “droop” and its now exposed column is actually dark green and slightly brown, but the hidden tentacles and oral disk are bright green.
