The region has more than 4,000 species of marine molluscs and a large diversity of marine fishes. Cone snails and stonefish carry poison that is fatal to humans. The Giant East African land snail arrived only in the 1970s but has already spread from the Port Vila region to Luganville. There are three or possibly four adult saltwater crocodiles living in Vanuatu's mangroves and no current breeding population. It is said the crocodiles reached the northern part of the islands after cyclones, given the island chain's proximity to the Solomon Islands and New Guinea, where crocodiles are common.
