Following the stranding of a number of sperm whales on the English coast last weekend, scientists from the Zoological Society of London (ZSL) and the Museum visited Lincolnshire from Monday 25 January to conduct autopsies on the dead leviathans.
I interviewed Rebecca Lyal, Cetacean Stranding Support Officer of the Cetacean Strandings Investigation Programme (CSIP), to find out what the autopsies have revealed thus far about the cause of death.
Rebecca, how do you go about assessing the cause of death of whales?
That can be done by looking at the recent movement of the whales, where they have come from and what their behaviour has been and then, once we’d deduced that they didn’t strand because they had got caught in a net, or had any wounds that may have made them unable to swim, we can start looking a bit deeper. This is when we started to take samples of the skin, the blubber, reading the blubber thickness, and then muscles and blood.
