有光合共生体的海葵Morphological adaptations for light capture in sea anemones with photosynthetic symbionts. Scale bars=2.5 cm. (a) Dimorphic tentacles of
Lebrunia danae (i) photosynthetic tentacles and (ii) colourless feeding tentacles emerging in response to a prey item. (b) Vesicles on the body wall of
Bunodeopsis antilliensis bearing symbiotic algal cells: at night, when feeding tentacles are extended; and by day when the feeding tentacles are retracted and the vesicles expanded. (Photographs of R Day.) (c) Tentacles on the oral disc of
Discosoma sanctithome (i), and capture of small fish prey by extension of the oral veil (2–4, see text for details). (Photographs of B Watson.)
