Fleas are small, wingless insects that are known for their ability to jump great distances. They are typically dark in color, ranging from reddish-brown to black, and have narrow, flattened bodies that are well-suited for moving through the fur of animals.
One of the key characteristics of fleas is their long, powerful hind legs, which enable them to jump up to seven inches vertically and thirteen inches horizontally. This ability, combined with their small size, makes them difficult to see and catch.
Another notable feature of fleas is their mouthparts, which are designed for piercing the skin of animals and sucking their blood. These mouthparts are sharp and needle-like, and are typically hidden beneath the flea's body when not in use.
Fleas are also covered in tiny hairs and scales, which help them to grip onto their hosts and prevent them from being easily dislodged. These hairs and scales also give fleas a rugged, spiny appearance.
Overall, fleas are small, agile, and well-adapted for life as parasites on animals. They may not be the most attractive creatures, but their ability to jump and their sharp mouthparts make them highly effective at what they do.
