Looks like the smallest shark in the world? Source:

In 1979, in the Eastern part of the Pacific ocean, the biologists caught the world's smallest shark. Its body length was equal to only 40 centimeters, so she was given a very plain name of "the American pocket shark". Whether because of her , or because of the rarity of the species, scientists were able to detect the second species only in 2010 in the Gulf of Mexico. And then, after examination of her skeleton revealed that the scientists made a mistake. Found the shark refers to a whole new kind and it is the smallest in the world.

Between sharks from the Pacific ocean and the Gulf of Mexico is really a lot of differences. Using a microscope and computer tomography, which allows to examine the inside of the body without opening the body, scientists have identified a second smaller number of vertebrae and the presence of luminous bodies. Length of the smallest sharks were equal to 14.4 centimeters.
