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, 10 genera occur.  Adults of different genera are small (2.5-10 cm SL) and vary considerably in their morphology, but all are characterised by a well-developed ventral adhesive disc. Clingfish larvae are previously undescribed from Australian waters.  In this paper, larval development of species from five genera: Aspasmogaster, Barryichthys, Cochleoceps, Creocele and Parvicrepis are described.  Larvae of the different genera varied in their body morphology and the size of notochord flexion, disc formation, fin development and pigmentation patterns during larval development.  Based on the observed differences in larval characters, the larvae of the five genera will be compared with the phylogenetic classification into sub-families based on adult morphology.
