The small dorsal fin is situated about two-thirds of the way down the body, closer to the fluke. Some dorsal fins are tall and hooked, while others can be almost triangular in shape. The pectoral flippers are small, while the flukes are rather broad. The tail fins, or flukes, may have a small notch in the centre and have concave trailing edges.
There is a marked indentation behind the blowhole.
Adults grow to between 5.5 and seven metres in length (18 to 23 feet) and reach about two to three tonnes.
This curious whale will occasionally summon the courage to investigate a boat, but is otherwise rather shy.
Before a dive, the Cuvier’s Beaked Whale will make between two and three blows, 10 to 20 seconds apart. Then, it will dip below the water’s surface and stay there for between 20 and 40 minutes. Before a dive, it arches its back, often lifting the fluke out of the water.
Sometimes, it will expose the top of its head while coursing through the water at an impressive speed.
The Cuvier’s Beaked Whale travels alone in the case of being an aged male, but is more commonly known for sticking to pods of about two to 10 individuals. This may increase to up to 25 individuals in some cases.
Where to Find Them
The Cuvier’s Beaked Whale has a global distribution in tropical, subtropical and temperate waters (that is, far away from the icy poles). It is often found in inland waters, like the Mediterranean, Gulf of Mexico, Gulf of California and the Caribbean.
This whale species feeds mainly on squid, as well as the fish that occur naturally in its deep-water home.
There are no specific known threats to the Cuvier’s Beaked Whale. Of course, whaling always presents a danger to any of these cetaceans. Interestingly, it also appears that this whale is particularly sensitive to noise. Far more stranding incidents have occurred after noisy naval operations, for example.
