Sorry for cross-posting! Dear all We observed an atypical inter-specific association in the Comoros archipelago, in the Mozambique Channel (south-west Indian Ocean), of an adult female Indo-Pacific humpback dolphin (coastal species) and a spinner dolphin calf (mostly oceanic in this area). Both individuals are generally associated with other humpack dolphins. According to local dolphin watching operators, this association is observed for at least six months (the animal was newborn). First observations reported a probable hybrid (with a Tursiops, already observed in this area), but there are evidences that the calf is definitely a spinner. I would ask if similar cases have been observed in cetaceans and even in other mammals such as primates.
