What Is Echocardiography? Echocardiography (EK-o-kar-de-OG-rah-fee), or echo, is a painless test that uses sound waves to create moving pictures of your heart. The pictures show the size and shape of your heart. They also show how well your heart's chambers and valves are working.
Taxonomy/Description. The Giant Otter's scientific name is Pteronura brasiliensis, which means winged tail belonging to Brazil, although this otter species is not limited to Brazil. Winged refers to the fin-like shape of the giant otter's tail. The giant otter is a member of the weasel family, Mustelidae, in the Mammalian Order of Carnivora.
The long, low lying body of the jaguarundi gives it a weasel-like appearance. The head is small and flat with small, low lying ears that gives the jaguarundi the face of an otter, hence the name otter cat. It has two color phases that can be present in the same litter. The first one is the black to gray phase.
