AI overview
Fleas are small, wingless insects that live as parasites on mammals and birds by feeding on their blood, with about 2,500 species existing worldwide. They matter because their physical adaptations—including powerful jumping legs, claws for gripping, and piercing mouthparts—make them difficult to remove from their hosts, allowing them to thrive as persistent parasites.
