Soft ticks lack the hard scutum present in the hard ticks . [3] The gnathosoma (or capitulum, the mouthparts-bearing structure) is located on the underside of the animal's body and is not readily visible, [3] while in the Ixodidae, the gnathosoma projects forward from the body. The lateral edges of the body are rounded.
Soft ticks in the family Argasidae are characterised by the mouth being on the underside, and thus not visible from above, and by having no rigid scutum, the sclerotised plate on the anterior dorsal surface, just posterior to the head, possessed by hard ticks. This species has a leathery, wrinkled dorsal surface covered with small nodules.
Soft ticks of the family Argasidae lack the hard scutum or shield present in hard ticks of the family Ixodidae. Their gnathosoma or mouth structure is located on the underside of the body and is not readily visible. Their feeding method differs from that of the hard ticks in that they do not embed a capitulum in the host, but make an incision ...

Ticks are widely distributed around the world, especially in warm, humid climates. Ticks belong to two major families, the Ixodidae or hard ticks, and the Argasidae, or soft ticks. Nuttalliella, a genus of tick from southern Africa, is the only member of the family Nuttalliellidae, and represents the most primitive living lineage of ticks ...
A third tick family, Nuttalliellidae, is less commonly discussed. [3] The primary distinction between soft and hard ticks is the amount of time they stay attached to their host. Soft ticks remain attached on the order of a couple hours and may take multiple blood meals from the same host.
Lifecyle of Ornithodoros soft tick. Argasidae soft ticks have different lifecycles from Ixodidae hard ticks, and these are very variable between species. [1] Typically, in Ornithodoros, a larva hatches from an egg laid in the nest or resting place of the host. The larva does not feed, but directly molts into the first nymph stage.
The Ixodidae are the family of hard ticks or scale ticks, [1] one of the three families of ticks, consisting of over 700 species. They are known as 'hard ticks' because they have a scutum or hard shield, which the other major family of ticks, the 'soft ticks' ( Argasidae ), lack.
