Estuarine crocodiles wait below fruiting Ficus racemosa fig trees for shark catfish Pangassius kinabatangensis (Ikan Patin in Malay) to arrive to feed on the ripe falling figs. Illustrations by Karen Phillipps.
An interesting article by Luke Evans describes how satellite tagged large estuarine crocodiles Crocodylus porosus on the Kinabatangan River habitually rested under trees that overhung the river and speculates that the crocodiles were waiting for Long-tailed Macaques that usually roost in such trees to fall or jump into the river. This probably does happen from time to time but it is more likely that the crocodiles are waiting for Shark Catfish (Ikan Patin) to arrive to feed on the figs that fall into the river.
