What is a "tick"?

A tick is a small arachnid that feeds on the blood of mammals, birds, and sometimes reptiles and amphibians, known for its parasitic nature and ability to transmit diseases to its hosts. Ticks have flattened bodies and are commonly found in grassy areas, attaching themselves to the skin of animals and humans to feed. They can be carriers of various infectious agents, making them of significant concern for public health.
