Sperm whales are one of the most mysterious creatures on the planet – sure, they’re the largest toothed animals on Earth, but you’ve got to be pretty lucky to see them (especially because they can hold their breath for up to 2 hours!). Miranda Van Der Linde made her own luck by becoming a marine biologist and scoring a sperm whale research gig in the Azores. In this episode of Wild Lives, Miranda’s stories will give you goosebumps on your goosebumps as she recalls watching all kinds of fascinating behaviours (including seeing them give birth)! She also reveals how they received such an unfortunate name, the secret ways they communicate, and why their vomit is worth a fortune.
