Clingfishes (F. Gobiesocidae) are a moderately sized family distributed worldwide in tropical and temperate regions in intertidal and subtidal marine waters. In southern Australia waters, ten genera occur. Adults of different genera are small (2.5-10 cm SL) and vary in their morphology, but all are characterised by well-developed ventral adhesive disc. Clingfish larvae are previously undescribed from Australian waters. In this poster, larval development series of three species from the genus Aspasmogaster – A. costata, A. liorhynchus and A. tasmaniensis are described. Larvae of the three species were similar in body morphology, size at notochord flexion, disc formation and fin development. Pigmentation patterns, particularly on the head and dorsally and laterally on the trunk varied between the three species and varied during larval development. Characters that allow identification of larvae of the three species from plankton samples are detailed.
