True's beaked whale fact sheet

Very little is known about True’s beaked whales, as they have only been positively identified at sea a few times. Most of what we know about them is from stranded individuals. Males are easier to recognise from their two distinctive teeth at the tip of the jaw which are visible even when the mouth is closed. However, it can be almost impossible to distinguish them from the similar looking Gervais’ beaked whale, but True's beaked whales have a rounder melon and a pale head.

True’s beaked whales are found in two distinct populations in the cool temperate waters of the north Atlantic and the southern hemisphere. It is not known if these two populations are different species.  As with other beaked whale species, confirmed sightings in the Azores are rare, but they may be present on a regular basis. In 2008 Futurismo had a rare close encounter with a small group that could be identified as True’s beaked whales and in 2012 we had a brief encounter. In 2015 we had a wonderful encounter with a female True's beaked whale and her calf.
