Fig. 1From: A comparative view of early development in the corals Favia lizardensis, Ctenactis echinata, and Acropora millepora - morphology, transcriptome, and developmental gene expressionComparative adult morphology of the species studied. (a) Small colony of F.lizardensis. (b) A closeup view shows that each of the circular or oblong structures surrounds a single polyp (arrowheads). (c) C.echinata is a solitary coral, consisting of a single large polyp. (d) Closeup of the central portion showing the slit from which the polyp emerges to feed. (e) The A.millepora colony is composed of many branches emerging from a single base. (f) Closeup of a few branches, each covered in many polyps. Each scale-like structure on the branch marks the location of a single polyp. Photo credits with thanks to: (a) Lawrence Cope, (b, c, e) Australian Institute of Marine Science, (2015).
