What is a shark afraid of?

A few months back we posted an article containing two videos, both of which show just how aggressive a goliath grouper can be. Well, here’s another.

Goliath groupers can can grow to 800lbs and 3 metres long and they are pretty much the baddest fish in the sea.

I once dived in Australia, on the Yongala wreck, which was home to an amazing amount of sea life, including a family of man eating bull sharks and an enormous grouper. The dive master who led the trip told us not to worry about the sharks – they’d never bothered anyone in years. The goliath grouper, on the other hand, was apparently a little bit moody and, in the past, when divers had swum too close, he’d been known to dislocate a few shoulders!! Ouch.

As you can see from this animated gif, groupers aren’t exactly afraid of divers or spear fishermen!
