Antagonistic behavior between two honeycomb cowfish, Acanthostracion polygonius Poey, 1876, at Curaçao

Antagonistic behavior between two honeycomb cowfish, Acanthostracion polygonius Poey, 1876, at... Reef sites Antagonistic behavior between two honeycomb cowfish, Acanthostracion polygonius Poey, 1876, at Curac¸ao The honeycomb cowfish, Acanthostracion polygo- nius Poey, 1876 (Ostraciidae) is easily distinguish- able from other Caribbean coral reef fish. Both females and males possess a heavy external bony box with uniformly hexagonal scale plates as armor, as well as a pair of spines projecting from the carapace above the eyes and anterior to the £ fin (Moyer 1984). They are known to feed on a variety of invertebrates, including tunicates, alcyonaceans, shrimps, gas- tropods, and at least 15 species of sponges (Randall 1967; Wulff 1994). During a coral reef biodiversity survey at Cur- ac¸ao (June 2017), two A. polygonius individuals were engaged in what appeared to be either a failed mating ritual dance or a male–male territorial dispute (Fig. 1). It is likely that the encounter is that of a male–male confrontation since the distinctive hum- ming sound of the male prior to gamete release was not heard, nor any spawning was observed (Moyer 1984). The fighting behavior resembled that of Lac- toria diaphana from the Indo-Pacific; upon seeing each other, the pair proceeded to flash and display their bright neon-blue coloration (Moyer 1984).
