Comparative morphology of the eye (with particular attention to the retina) in various species of cardinal fish (Apogonidae, Teleostei).
Various parameters of the eye dimension and structure have been compared in 15 species of cardinal fish (Apogonidae), including both nocturnal and diurnal forms, mostly inhabiting rocky habitats in tropical and subtropical regions. In general, in the nocturnal forms the eye and retina are larger than in the diurnal fish of similar dimensions. In the nocturnal species, eye diameter to body lengt...
متن کاملEvolution of ontogenetic dietary shifts and associated gut features in prickleback fishes (Teleostei: Stichaeidae).
We tested the hypothesis that an ontogenetic dietary shift from carnivory to herbivory or omnivory, and concomitant changes in the gut facilitating digestion of algae, are synapomorphies of the tribes Xiphisterini and Esselenichthyini in the family Stichaeidae (pricklebacks). Previous investigations have revealed that two xiphisterine pricklebacks-Xiphister mucosus and Xiphister atropurpureus-b...
متن کاملPhylogeny of cardinalfishes (Teleostei: Gobiiformes: Apogonidae) and the evolution of visceral bioluminescence.
The cardinalfishes (Apogonidae) are a diverse clade of small, mostly reef-dwelling fishes, for which a variety of morphological data have not yielded a consistent phylogeny. We use DNA sequence to hypothesize phylogenetic relationships within Apogonidae and among apogonids and other acanthomorph families, to examine patterns of evolution including the distribution of a visceral bioluminescence ...
متن کاملGut length and mass in herbivorous and carnivorous prickleback fishes (Teleostei: Stichaeidae): ontogenetic, dietary, and phylogenetic effects
Relative gut length, Zihler’s index, and relative gut mass were measured in four species of prickleback fishes and the effects of ontogeny, diet, and phylogeny on these gut dimensions were determined. Of the four species, Cebidichthys violaceus and Xiphister mucosus shift to herbivory with growth (>45 mm SL), whereas X. atropurpureus and Anoplarchus purpurescens remain carnivores. A. purpuresce...
متن کاملA new species of the cardinalfish genus Jaydia (Teleostei: Apogonidae) from the Philippines.
Jaydia erythrophthalma n. sp. is described from specimens collected during two recent biodiversity surveys along the east and west coasts of Luzon, Philippines. It is characterized by a first dorsal fin with eight spines, serrated posterior and crenulated ventral preopercular edges, reddish orange iris and two series of brown spots tinged in orange on the upper part of the body.
