Giant gathering

Tony Wu's Image

Dozens of sperm whales mingled noisily off the coast, stacked as far as Tony could see. Immediately, he realised that this was something special – like a gathering of clans, these whales were part of a multi-day congregation. For Tony, the sight filled him with hope that ‘the recovery of sperm whale populations may be going well’.

The marble-like appearance of these whales is a sign of skin-sloughing. Large aggregations like this one will rub and roll against each other to exfoliate their neighbour’s dead skin, helping them to maintain hydrodynamic performance. The tactile contact also helps to reinforce social bonds.

Tony devotes most of his time to researching and documenting rarely seen marine animals and environments, spending more days at sea that he does on land. After spending years photographing tropical reefs, whales and large aggregations of spawning fish, he is currently exploring the varied and diverse marine environments of Japan, which encompass everything from tropical to Arctic environments, as well as many unique habitats in between.
