The dolphin is found only off the coast of Chile; it is commonly referred to in the country as tonina. == Characteristics == === Physical description === The Chilean dolphin is small at around 1.7 metres (5 ft 7 in) in length, with a blunt head. Adults reach up to 60 kg, with females slightly larger than the male bulls. This dolphin is thickly shaped with its girth up to two-thirds its length. Their small and thick shape is often mistaken for other types of porpoises. The dorsal fin and flippers are small in proportion to body size in comparison with other dolphins. The throat, underside, and the closest part of the flippers to the body are white. The remainder of the body is a mix of greys. A black line connects their blowhole, eyes, and dorsal fin. It has 28–34 pairs of teeth in the upper jaw and 29–33 in the lower. The two eyes are positioned at the ends of the mouth lines, giving the appearance of a smile. The tail has a characteristic notch in the middle.…
