A rare, endangered baby dolphin has been spotted swimming with members of a different species in Cambodia, leaving scientists puzzled.
The Irrawaddy dolphin (Orcaella brevirostris) calf was likely with its mother in a group of Indo-Pacific humpback dolphins (Sousa chinensis). Irrawaddy dolphins are dark gray with squished faces, while Indo-Pacific humpback dolphins are pink with long noses, so the calf and mother stuck out like saw thumbs.
