As my skull of the month for December is the sperm whale I wanted to find out a bit more about the animal, including it’s foraging behaviour. Wuite a few different methods have been used to investigate this area and found that the whales can dive to a depth of 400 – 1200m for up to 138mins.
The titled article by Watwood et al. (2006) wanted to go beyond this and try to identify when the foraging events happen during a dive. By listening to the vocalizations of the whales, and the differences in the clicks that they make they were able to establish at what depth the whales began detecting and foraging for prey. The overall conclusion supported the previous studies work on sperm whale foraging where an average dive duration lasted between 40-50 mins and dived to 400 – 1200m. They also made an additional comment that sperm whales have one of the highest diving efficiencies when compared with other diving animals. This shows that the sperm whale has become a very efficient predator
