It has yellowish spines that lie flat against its body (1), but when threatened stand up, looking similar to a porcupine's quills. The Globefish is one of the smallest members of the Diodontidae family, and it's scientific name is Diodon nicthemerus.  They usually growing to around 15cm, although they can grow up to 30cm.  

Globefish are native to Australia and can be found in southern waters, most commonly in Port Phillip Bay and the coastal waters of Tasmania. The Globefish can be found anywhere from 0 metres to 85 metres under water (1)

The Globefish has few predators due to three defence mechanisms. When threatened, it will rapidly inflate itself with water and/or air to become spherical in shape and causing it's spines to stand up, restricting its predators to creatures with larger mouths and making it very difficult to attack (1). Globefish are also poisonous, storing tetrodotoxin within their organs (2). Consumption can be fatal, and NO ANTIVENOM HAS BEEN DEVELOPED!!!

Humans sometimes remove the Tetrodotoxin and eat Globefish.

Rules are now in place to regulate fishing, but still, habits are threatened. Globefishes habitats are coral reefs, so perhaps we could create an artificial reef with plenty of holes for the globe fish to retreat into!  Not only would this help the Globefish it would also provide shelter for other native fish. We could use old bricks with holes or wooden crates.]]> 2017-03-22 05:30:47 UTC https://padlet.com/castlj/GF/wish/161711115 Threats castlj https://padlet.com/castlj/GF/wish/161988547 The Globefish main predators are sharks, whales and sea snakes, as some of these species are unharmed by Globefish toxin, and they find them  a tasty starter... 

Humans have made havoc in Port Phillip Bay, with over fishing and destruction of reefs. Global warming is causing the water to get warmer, and pollution is reducing the living space for fish. This causes loss of habitat and loss of food which means there are less globefish and could possibly lead to extinction.
