Dear Marmam subscribers,

I am currently working on resident common bottlenose dolphins in Rangiroa, French Polynesia,

with a local NGO and the IRCP-CRIOBE research center.

One of the groups contains a juvenile melon-headed whale first observed last November

when it still was a calf and regularly seen with the bottlenoses since then. This is not the first time that these dolphins are seen with

calves from other dolphin species and I would be really interested to know if someone knows of similar recurrent cases elsewhere?

I would also be keen to have people's views about these phenomena.
