Abstract
Based on the examination of almost 1200 specimens representing 50 species of the secondary deep-sea fish genus Neobythites (family Ophidiidae), this study provides an overview of body coloration and a detailed comparison among species that have typical ocelli or eyespots consisting of a dark spot surrounded by a contrasting pale ring on their dorsal fins. Special interest concerns the possible functions of ocelli as antipredator and social signaling devices and the hypothesis that species differences in ocellus size and position are more pronounced in areas of overlap. Color patterns were found in 78% and ocelli in 44% of the Neobythites species. The 22 ocellus-bearing species occur at shallower depths than those without. Ocellus number varied between one and four ocelli with single-ocellus-bearing species reaching shallower minimum depths than those with multiples. Variation in both ocellus size and position was found among co-occurring species with a single ocellus. For instance, the Northern Indian Ocean population of N. stefanovi differs in ocellus position from the co-occurring N. steatiticus, while the allopatric Red Sea population of N. stefanovi does not. This evidence of character displacement is also supported by the marked difference in ocellus position and size between two specimens of N. meteori that were collected widely separated from each other and co-occurring with two other single-ocellus-bearing species in the Pacific and Indian Ocean, respectively. Ocelli in Neobythites may therefore serve antipredator as well as social communication functions.
