Saltwater Crocodiles (Crocodylus porosus) thankfully still exist in Palau’s mangroves and in the beautiful Rock Islands and can potentially be found anywhere on the island. Despite their fearsome and, in some areas, very justified reputation, here they rarely grow to the immense size that they do in Australia and New Guinea. There was only one fatal attack by a crocodile in Palau within recorded history and that occurred in 1965. The biggest crocodile in Palau’s history was 15 feet in length- large, but this is an average size for saltwater crocodiles in most other countries. The rarity of attacks probably stems from the fact that there are no more than 150 adult individuals currently on the island.
Snorkeling and scuba diving are very popular in Palau and there has never in recent history been a report of an attack on a tourist. Judging from a recent survey, it appears crocodiles are quite unjustly hated by the locals, in harsh contrast to the worship they are given by the indigenious peoples of Australia, New Guinea and the Solomon Islands. The reasons for this are unclear.
Bull Sharks are common in the coastal waters and estuaries, so caution must always be taken while scuba diving or snorkeling
