Ciguatera poisoning is prevalent and can result from eating coral reef fish such as grouper, snapper, sea bass, jack, and barracuda. The ciguatoxin is not destroyed by cooking. Risk is low due to expected low quantities to be consumed. Swimming-related hazards include sharks, jellyfish, the Indo-Pacific man-of-war, stonefish, scorpion fish, stingrays, sea snakes, spiny sea urchins, sharp coral, poisonous cone shells.
Stonefish, scorpion fish and stingrays congregate in shallow water along the ocean floor and can be difficult to see. Wearing wetsuit booties may help, but should not be relied upon as complete protection due to the long rigid spines penetrating the booties. The jellyfish population is increasing, due to overfishing of jellyfish predators, rising water temperatures, and pollution. Jellyfish travel in groups.
Box JellyFish Can be found all year round but are more plentiful from October to May. Local contacts have not reported any sightings this year in West New Britain area. Stinger Suits are recommended.
