How many body segnets des it have?

Answer 1

The major families of tick include the Ixodidae or hard ticks, they have thick outer shells made of chitin, and Argasidae or soft ticks, which have a membraneous outer surface. Soft ticks typically live in crevices and emerge briefly to feed, while hard ticks will attach themselves to the skin of a host for long periods of time. Tick bites look like mosquito bites, but can also bruise or resemble a bullseye.

Ticks have unsegmented (one) prosoma generally covered dorsally by a solid carapace.
