Hello thank you for your @jacintasevilla contest, I followed your suggestion and I was interested in the bottlenose dolphin.
This mammal can reach a length of 2-4 meters, weigh between 150 and 650 kg and live up to 20 years. Males are larger than females. Bottlenose dolphins swim at speeds of 5 to 11 km/h but can burst at 35 km/h for short periods.
It has powerful, sharp, cone-shaped teeth, arranged in 18 or 26 pairs on each side of its jaw.
They are required in a variety of activities ranging from therapies for people with a disease, to enemy attacks and mine detection in the United States.
I made a naive drawing, because I think dolphins have an aura similar to that of children, clean and sensitive.
