Shark talk

7 Nov

We have just had a very interesting – if somewhat scary – talk from Michael Burgess of the Department of Fisheries (shark response untit manager). Apparently the increasing number of shark sightings in the area is connected to the larger number of whales travelling in the waters of Western Australia this year. The sharks seem to follow the whales, hoping to find whale carcasses – a number of the fatal shark attacks occurred at or close to the beaches where carcasses had previously been washed up. Research has also shown that while great whites do seem to generally prefer colder water temperatures, there are times when they move to warmer areas – thus the idea that you won’t see a great white shark if there are no seals around, isn’t quite right.
