2. Figure 1 The unusual lips of tubelip wrasses.
(A) A typical wrasse Coris gaimard; (B) a tubelip wrasse Labropsis australis. Scanning electron micrograph images of the lateral view of the lips of (C) C. gaimard and (D) L. australis. (E) Still image of L. australis feeding on coral (Acropora sp.). (F) A schematic diagram of the potential feeding mechanism used by tubelip wrasses to feed on coral mucus and tissues. The mucus on the lips may offer protection from nematocysts, help the lips seal with the uneven surface during suction, and help enclose dislodged mucus and tissues. Dashed arrows indicate the flow of the mucus during the suction. Scale bars = 500 μm. See also Figure S1. Photo in (A) courtesy of J.P. Krajewski.
