Shark in Australia
Lecturer : Today we’re going to look at one of my favourite fish—the shark. As you know, sharks have a reputation for being very dangerous creatures capable of injuring or killing humans, and I’d like to talk about sharks in Australia.
Sharks are rather large fish, often growing to over ten metres and the longest sharks caught in Australia have reached sixteen metres. Sharks vary in weight with size and breed, of course, but the heaviest shark caught in Australia was a White Pointer—that weighed Q31 seven hundred and ninety-five kilograms —quite a size! Sharks have a different structure to most fish: instead of a skeleton made of bone, they have a tough elastic skeleton of cartilage.
