Fig. 3 in Histopatological effects of bleaching and disease on the coral Siderastrea stellata from coastal reefs of Brazil

Fig. 3. Photomicrographs of organisms associated with bleached sample (a) black arrow is pointing to diatom (see striated frustule) on the surface of corals. The epidermis is atrophied and cuboidal and gastrodermis is bereft of zooXanthellae (atrophy) and markedly vacuolated; b, dead autolyzed tissue with another likely diatom (black arrow); c-d, dissociated tissues with fungal hyphae (black arrow); d, shows fungal hyphae (black arrow) invading coral tissue with necrosis.
