| Diagnosis | Description: This sea-anemone presents 2 forms, of different aspect and living distinct biotopes, called ecotypes. Ecotype I: 70 to 192 tentacles (in the majority of the cases, this number is included/understood between 142 and 148); Pedal disc of a diameter from 2 to 5 cm. Type II: higher proportions, since it has approximately 192 tentacles and more (even up to 348), with a pedal disc of about 15 cm in diameter. Vertical size, tentacles included/understood: 50 cm. At these 2 ecotypes, the tentacles, with a size of approximately 20 cm, are length higher to the diameter of the oral disc; they are very fine and mobile, but not very contractile. They are laid out in 6 concentric crowns around the siphonoglyphe, and are thinned gradually. Colorings of the 2 types are conditioned by the presence or the absence of symbiotic algae; and are of this fact very fluctuating: white with the tone greens; while passing by the gray and the brown one. Their end frequently raises a bulge of color violet (Ref. 358). |
