Coloured scanning electron micrograph (SEM) of a dog flea (Ctenocephalides canis). The flea lives as an ectoparasite on a variety of mammals, particularly domestic dogs and cats. The flea's mouthparts are adapted for piercing skin and sucking blood. Dogs often experience severe itching in association with flea infestation. The fleas may occasionally bite humans, but cannot breed without their preferred hosts. The flea body is laterally flattened and covered with spines and bristles. This shape helps with forward movement through dense fur, prevents dislodgement and steadies the flea during feeding. The flea's elongated hind legs are well-adapted for jumping. Dog fleas can jump an average distance of 30 centimetres and an average height of Magnification: x40 when printed at 10cm wide.
