#hematophagous

• Aphanipteran — A small, wingless parasitic insect in its adult stage, structurally adapted for jumping and hematophagous feeding (blood-sucking), belonging to the order Aphaniptera (also known scientifically as Siphonaptera), which includes fleas. Their bodies are laterally flattened, protected by a rigid chitinous exoskeleton, and equipped with highly developed hind legs designed for executing expansive leaps onto host organisms.
• Anopluran — A small parasitic insect of the order Anoplura, wingless, with mouthparts adapted for piercing and sucking, living on the bodies of mammals and feeding exclusively on their blood. Representatives of this structural group are strict hematophages and hold major medical and veterinary importance, being recognized biological vectors for transmitting severe pathogens, such as epidemic typhus.
• Argas — A genus of soft-bodied parasitic ticks in the family Argasidae, lacking a chitinous dorsal shield, which primarily attack domestic and wild birds, but also accidentally mammals or humans. These hematophagous arachnids are nocturnal, hiding in the cracks of shelters during the day, and represent major biological vectors for transmitting dangerous pathogens, such as bacteria and viruses.
