There are many recent records of dolphins and whales interacting in playful ways. Dolphins favoured slow and gentle behaviours such as bow-riding, meandering, touring and belly rolls. The whale species each responded differently to the dolphin behaviour. Humpback whales most often moved their pectoral fins towards the dolphins and also presented their bellies, rolled and moved upside down. Grey whales most often rolled, and southern right whales displayed pectoral slaps. All of these are friendly socialising actions similar to courtship.
