Human fleas (pulex irritans) prefer to feed on humans and pigs, but are much more commonly associated with living on wildlife. Dog fleas (ctenocephalides canis) are much more suited to living in fur. Their flattened bodies help them navigate and move their way through fur or hair, and their backwards facing spines help them cling to the fur.
