Whale3

One of a pair with 25% white flukes

Humpback whales in Hawaii are most commonly found in pairs. This whale was sighted with another adult whale. Pairing up makes sense given that the whales are in Hawaii for the breeding season. Pairs often contain a male and a female. Male–male pairs are also found but female-female pairs are quite rare. When a group of males forms to compete for mating access to a female, the males can be quite aggressive with one another. But in social groups that lack a female, males can appear passive, companionable or rowdy.
