Pliosaur

Gutting channels

These teeth are unbelievably big, and belong to the scariest sea monster that has ever lived – the pliosaur. The grooves along the length of the teeth serve a gruesome function…stop reading here if you’re squeamish! Without the grooves, as the teeth sunk into the prey animal’s body, suction could hold them in, making it more effort for the attacking animal. The grooves, however, allow blood and other body fluids to run out, avoiding any suction. The gutting channel on a bayonet performs just the same function. Nasty!
