Chegodaeva, O. Voskoboinikova] The development of pigmentation of the Fedorov eelpout (Zoarces fedorovi) from hatching out of egg integuments to delivery is studied. In Z. fedorovi, the adult coloration develops immediately, without larval coloration, obviously, due to viviparity. Comparative analysis of the sequence of anlage and morphogenesis of elements of the cartilaginous skeleton and the bony skeleton demonstrated that the sequence of anlage of cartilaginous and bony regions of the skeleton of Z. fedorovi principally correspond to the sequence in Z. viviparus and in other perciform fishes. Morphogenesis of the bones of ethmoidal and interorbital regions of the skull, of the axial skeleton, and of the skeleton of the caudal fin is highly similar in eelpouts and other fishes of the suborder Zoarcoidei, differing from that in the generalized perciform fishes. At the same time, the larvae of Z. fedorovi in comparison with Z. vivparus are characterized by a higher rate of development of the skeleton. Advanced structural traits in structure of the skeleton of larvae of Z. viviparus in comparison with Z. fedorovi are pointed out. Differences in size at which anlage of bony elements occurs, as well as in the formation of particular bony elements seem to indicate to a rather prolonged divergence of these species.
