Bones are green due to harmless pigment. Skin slimy and variable color (Ref. 35388).
Body shape (shape guide): elongated.
Inhabits rocky shores under stones, among algae and in tide pools, between tide marks down to 40 m. May remain out of water under rocks or seaweeds (Ref. 31184). Feeds on gastropods, chironomids, crustaceans, eggs and fry of fishes. Gives birth to live young (Ref. 9900). Bones colored green by the harmless pigment Vivianit (Ref. 4645). Breathes air when out of water (Ref. 31184). Mating takes place in August - September with internal fertilization of the eggs. Female give birth to 30-400 developed young (35-55mm) (Ref. 35388).
