Альтернативные названия: Potato Grouper, Potato Bass, Epinephelus tukula
The Potato Cod is a large and robust species of fish, native to Australia, but it can also be found in Asian countries.
The Potato Cod is a very curious fish so it's not uncommon for divers to have a close encounter with this massive fish. Also they are usually harmless and quite friendly towards divers. But be careful, if you stop paying attention to them, they can get a little bit jealous, so they will start to bother you to gain your attention.
An interesting fact is that they can change the shade of their skin to reflect their mood.
