Lego Animal Minifigure: Classic Dark Gray Shark
The first dedicated LEGO shark figures were included in two sets of the Pirates theme in 1989. These sharks are colored in dark grey and it consists of two pieces: the body (including the lower jaw, the tail and the fins) and a separate head piece with the upper jaw that allowed the mouth to be opened or closed. The interior is hollow, so that the shark could swallow little objects which could measure up to 1 stud in diameter.
