Crested Morwong
Crested Morwong may have an odd name, but then again they're a bit of an odd fish with their yellow and black stripes and strange looking crest.
We're not sure why they chose their fancy looks - it is not normally a good strategy to stand out underwater with hungry sharks around, especially if you're good to eat rather than toxic like most brightly coloured fish.
Crested Morwong are clearly bright fish but they're definitely not too intelligent.
