Imagem de Pteraster Müller & Troschel 1842

Descrição:

Another individual from subtidal Sares Head. Note the flabby-looking aboral side, caused by the extra membrane above the actual aboral side. This individual will be in danger of dying when placed back into seawater if any bubbles have gotten into the space between the outer membrane and the aboral surface, because it will cause the animal to float around the tank uncontrollably. This species is best left submerged at all times. Photo by Dave Cowles, July 2000.
