This species is the largest of the odontocetes, as it is equal to the whales in size. Its gigantic head, its dark striated skin and its small dorsal fin stand out. Apnea for more than an hour to search for food more than 2,000 meters deep. It is more common to see them in spring. Weight: 15-60 tons. Size: 11-18 meters.

Pilot whale: It is morphologically very similar to the tropical pilot whale, but it differs in the gray color of its skin (almost white in some adult specimens) and the contrast with the dorsal fin, which is still dark. Weight: 300-600 kg.

It is similar in appearance to the fin whale, although the fin whale is smaller and more robust and has a unique feature in the Family, which are the three dorsal ridges instead of a central one. The length in males is 13.7 m and in females 14.5 m, with a maximum length of 15 m. The back is dark bluish gray to metallic gray, with lighter flanks and pale throat and belly.

Striped dolphin: Thanks to its bluish coloration and the stripes (stripes) that go from the eyes to almost the tail, this dolphin is very easy to identify. He is sometimes elusive with boats, although he is a very fast swimmer who likes to jump out of the water. Weight: 100-130 kg. Size: 2.7 meters.

Rough-toothed dolphin: The stretch marks on its teeth and its elongated skull are the most representative characteristics of this species. It is a dolphin darker than the bottlenose and has lighter spots. They are distributed in groups of 6 to 10 specimens. Weight: up to 150 kg. Size: up to 2.7 meters.

This species is characterized by the specks that cover most of its skin in adulthood. They form large groups and have a very active behavior. They can be seen more frequently from fall to the end of spring. Weight: 60-80 kg. Size: up to 2.3 meters.
