Boxfish; White Barred

 

Occurrence at the Busselton Jetty: Female White-barred Boxfish are commonly seen from the underwater observatory, occasionally we are lucky enough to see large brightly coloured males and very small (approx. 2cm) juveniles of the species taking on the same colour pattern as the females.

Anoplocapros lenticularis
White Barred Boxfish
The white-barred boxfish has distinctive white bands on the head, lower back and tail and are characterised by their high domed back. Males are bright orange to red, while females and juveniles are yellow growing to a maximum size of 20cm.
 
The species is found near moderately exposed reefs and jetty pylons from Dongara in WA around the southern coast to Lorne in Victoria. The white-barred boxfish falls in the Order Tetradontiformes, which includes pufferfish, toadfish, porcupine fish and globefish, all of which contains the extremely potent poison, tetrodotoxin.
 
This poison is one of the most lethal, naturally occurring toxins known, and occurs in the skin and the organs, including the eggs, of these fish.
