Anthopleura elegantissima (sandy or aggregating anemone)

This light greenish individual varies in size, but can grow up to 8 cm wide across the crown. It is typically found living in groups with other anemones near by. Anthopleura elegantissima is commonly found covered with bits of gravel, sand or shell to protect itself against dessication. These anemones can be found in abundance on rock faces, and in tidepools or crevices, forming squishy colonies that squirt water when touched or stepped on.

 

Anthopleura xanthogrammica (giant green anemone)

This uniformly green individual is typically larger in size than its cousin, Anthopleura elegantissima. These anemones grow as large as 25 cm in diameter across the crown and are heartily carnivorous. Usually found in tidepools or crevices, they are commonly covered with bits of gravel and shells to protect against dehydration. Its green hue is due to its symbiotic relationship with green algae. When in water, this beautiful organism opens up its tentacles and waits for its meals. (more images 1)

This strange creature has taxonomists perplexed as to whether to label it plant or animal. This fern-like creature is usually arranged in clusters and is brownish, orange or tan in color. Its life cycle involves two stages, including stationary plant and mobile animal phases. The ostrich-plume hydroid can be found on rocks or in other semi-protected shores.
