The front flippers are long and narrow. The trunk is deep and somewhat barrel-shaped with a posterior taper to a blunt point. The shell is covered with a distinctive rubbery skin instead of horny plates. Sometimes a turtle will mistake an inflated plastic bag for a jellyfish, their main food, and eat the bag. The bag blocks the digestive tract and kills the turtle.
People dig up the eggs for food.
Leatherbacks are also accidentally caught in fishing nets and are drowned. Pronghorn antelope are native to the prairies of North America. At one time they numbered in the millions and were found on the open plains from the Mississippi River to the Rocky Mountains and from Mexico to central Canada. The name pronghorn comes from the pronged or sharply pointed horn of the male antelope. The females' horns are smaller and more slender.
