Pilot whale

Suborder: Odontocetes
Family: Delphinidae
Common name: long-finned pilot whale
Scientific name: Globicephala melas
Size: From 6 to 8.5 m maximum
Weight: males: up to 3.8 tons, females: 1.8 tons
Dorsal fin: placed in front of the back rather high, but strongly curved, wide at the base
Lifespan: 40-50 years
The Long-finned Pilot Whale is present almost everywhere in the North Atlantic.
Groups of several dozen individuals can be seen in our waters from May to September.
If it is a male, he can reach up to 8 m in length (average 6 m). As the name suggests, his head is shaped like a globe. The frontal protuberance known as the "melon" is particularly large in older males. When it comes to blow at the surface, we see the melon first, then the blow (easier to hear than to see), the dorsal fin, the back and sometimes the tail. Very gregarious, he moves and usually feed in groups sometimes importants. An obvious characteristic when stranding occurs. It is not uncommon then for entire groups to be found on the shores. A phenomenon observed a few times in our islands:
September 1978: 63 on the West Coast of the Isthmus, and one or two days later 93 near Pointe aux Alouettes (North-east coast of the Isthmus) for a grand total of 156 animals.
