Photo of Animalia: species: Acropora intermedia (Lizard Island Field Guide)

Branch tip of Acropora intermedia showing the diagnostic features - radial corallites are in two sizes, with the larger ones relatively long, often downward curved at the tip and with a long dimidiate opening giving a rasp-like appearance. Fine brown lines on the coenosteum underneath the polyp are also typical.
