| The cynodontid fish Rhaphiodon vulpinus Agassiz, 1829, known as "peixe-cachorro", is the only species of the family oceurring in the Pantanal of Mato Grosso. The initial development of its larvae was characterized, based on material collected with a 500 µm mesh size plankton-net, in several biotopes of the Pantanal of Barão de Melgaço, State of Mato Grosso, Central Brazil. The analysis was carried out with 72 larvae with standard length (SL) between 4.7 and 13.8 mm. The morphometric measurements varied positively with standard length, and body proportions ranged 8.1-17.8% for head length (HL), 6.2-10.1% for body height, and 63.673.5%, 16.8-21.6%, and 61.8-78.2% SL, respectively for pre-dorsal, pre-pectoral and pre-anal distances. The eye diameter varied... |

| This work presents the characterization of larval external morphology of the kissing gourami Helostoma temminckii, an aquarium fish of the family Helostomatidae, reared all over the world. A total of 38 larvae (standard length between 3.2 and 10.1 mm), obtained through natural reproduction carried out in the Fish Culture Station of the Federal Rural University of Pernambuco, were used. The morphometric measurements pre-dorsal, pre-pectoral and pre-anal distances, and body height varied positively with standard length, and body proportions varied between 30.8 and 51.2%; 12.9 and 37.9%; 38.2 and 58.3%, and 17.2 and 30.43% CP, respectively. The eye diameter varied positively with the length of the head (CC), but its body proportion decreased with growth,... |
