(A) From top to bottom:
a blue whale (pale grey skin colour, the lightest species)
a sperm whale (dark grey skin colour)
a fin whale (black skin colour, the darkest species).

(B) Differences in density of melanocytes (thick bars) and melanin (thin bars) amongst the three studied species
(C) Association between melanin abundance and melanocyte counts in whales. Grey dots correspond to blue whales, black dots to fin whales and crosses to sperm whales.
Sure enough, fin whales got the least sunburn.a sperm whale (dark grey skin colour)
