Pink Sea Star - Pisaster brevispinus -

Description: 50 to 70 cm radius; pink to lavender in color with short spines; soft and smooth appearance; slimy and prickly to touch.

Habitat: More commonly found in subtidal areas of mud and sand, this sea star is also seen on floats and pilings.

Natural History: It preys upon sand dollars, tube-dwelling polychaetes, mussels and other bivalve molluscs. It feeds by either digging into the substrate and pulling up clams or by extending its stomach over its prey and digesting it. It can not tolerate exposure to the air for long periods. (I put it back in the water).

Pycnopodia helianthoides
The Sunflower Sea Star

Description: Commonly 65 cm radius, but some large specimens reach 1 m across; orange, yellow, red to brown, sometimes purple; broad central disk with approximately 24 soft flexible arms.

Habitat: Commonly found on sand or gravel bottoms, and often on dock pilings.

Natural History: This is our largest and fastest sea star. Its soft, flexible body and numerous tube feet allow it to move quickly. It has been observed moving over sand or gravel at speeds up to 3 meters per minute. It feeds upon a large variety of organisms which include urchins, sand dollars, bivalves and sea cucumbers. It will also scavenge upon dead fish. Its mere presence causes many animals to show a dramatic escape response.

Hi Feather,
Your Sea stars wear amazing colours. Very modern, in a way. I think I must really once go and sea the Pacific Ocean..
