**Tick (Ixodida order)** - Parasitic arachnids that feed on blood. - Known for spreading diseases like Lyme disease. Ticks (order Ixodida) are parasitic arachnids that feed on the blood of mammals, birds, and reptiles. Though tiny, they pose serious health risks due to their ability to transmit diseases like Lyme disease, Rocky Mountain spotted fever, and anaplasmosis. Ticks latch onto hosts using specialized mouthparts, piercing the skin and feeding for hours or even days. Found in grassy, wooded, and humid environments, ticks are most active during warmer months. They detect hosts through body heat and carbon dioxide, then climb aboard to feed. After engorging, they drop off to continue their life cycle. Preventing tick bites involves wearing protective clothing, using repellents, and checking for ticks after outdoor activities. Despite their reputation, ticks play a role in ecosystems, but their potential to spread disease makes awareness and prevention essential.
