Some sharks give live birth, and some sharks lay eggs. Hammerheads fall into the former category, and can have 50 pups in one litter. However, hammerhead mothers don't provide any parental care, so I guess this one in the drawing stuck around long enough for a photo but has since swam off.

This is another image for the shark-themed birthday party series of illustrations. Hammerheads are easier to draw than pointy-nosed sharks because it's impossible to mistake a hammerhead for anything else.
