The grampo it is a very acrobatic animal, it is a dolphin of which they exist quite a few interesting hybrids and very bulky, no doubt. Keep in mind that these animals can reach a length of almost 5 meters, especially if males, and a weight that exceeds 300 kilos. Not bad, right?

Grampo: characteristics

We can define the Grampo a very large dolphin, so large that it cannot be confused with any dolphin belonging to another species. It is not only the size that makes this animal different from its peers, its color is also very particular. The grampi, in fact, they have a dark colored body but strewn with white scars, especially on the back and sides. These are not real scars, however, because it is obviously impossible for all specimens to have them like this.

They are mostly the effects of one poor pigmentation of damaged tissues and a very slow healing process. Scars thus may have been caused by other animals that the grampi have struggled with or by the squid that stung them. As age advances, scars also increase and when this dolphin is old, it is almost white for as many as there are scars that reports on your body.

There head of this animal it is much rounder than that of other dolphins, and has no sign of a beak, the upper jaw has no teeth while the lower one usually has a pair or at most seven. Always the head shows a peculiar feature that catches the eye rather easily. This is a groove located in the front that increases in size over the years.

It may be impressive to some but when the stalk makes its vocalizations, the skin covering this opening begins to throb. Also on the head we also find a very large and crescent-shaped blowhole, and then there are the eyes which are small, compared to the total size of the animal. They have an elliptical shape and can also be circled, meaning with a black or gray halo around them.

Let's move on to the body of this dolphin, a body fitted with a dorsal fin, high and curved, and of two long and thin pectoral fins. There is still another fin, the caudal one, very important for the backbone because thanks to it it can swim at 28-32km / h even if its average speed is 6-7 km / h.

Grampo: where he lives

Belonging to the family Delphinidae, the rasp in the scientific world is called Grampus griseus and lives in all temperate and tropical waters of seas and oceans of both hemispheres. We can find them then in Newfoundland, in Norway, Alaska but also in South America and South Africa, close to southern Australia and New Zealand.

Even gulfs can be suitable for this animal, gulfs like that of Mexico, for example, or like those of California, the Red Sea, the Persian Gulf, the Sea of ​​Japan and the Mediterranean Sea. Grampi prefer to live in deep waters, between 400 m and 1000 m deep.

Grampo: character

This animal does not have a solitary character, we find it swimming in seas and oceans in groups that can count up to thirty specimens, up to the hundred. In truth, it is not a causal choice, it all depends on the amount of food that is available in a certain area and, obviously, the more there is, the more grampi move there. In larger groups, subsets of same-sex or same-age grampi tend to form

The stalk is an animal social and also sociable, since it often swims with other dolphins such as bottlenose dolphins with which it has also given birth to hybrids.

Grampo: nutrition

L'diet is based on crustaceans and cephalopods but if he had a choice, he would only eat squid. If we know so much about her diet, we can say little about her sexual life and reproductive practices. Studies on this matter are not abundant, moreover, but we can now hypothesize that the small grampi are born in summer, when it is hot.

More interesting news about the life of this huge dolphin concern its communication methods. It is in fact able to emit many sounds, including the typical clicks of echolocation, in theory there could be typical sounds for each specimen that allow each individual to be recognized.

Grampi in the world

For now there is no risk of extinction for the grampi which do not belong to the threatened species even if in some countries such as Japan, it is hunted and killed quite frequently and this could lead to a worsening of the situation. It is not only Japan that is putting the stem at risk, there are also Sri Lanka, the Caribbean and Indonesia among the countries where the stem is regularly caught and in some cases it is even eaten at the table.
