what is the first one about?
They are large ones and contain over 700 species of hard ticks with a scutum or hard shield.
Tick
Three families of ticks are described. The two large ones are the sister families of Ixodidae (hard ticks) and Argasidae (soft ticks). The third is the Nuttalliellidae, named for the bacteriologist George Nuttall. It comprises a single species, "Nuttalliella namaqua", and is the most basal lineage. It is found in southern Africa from Tanzania to Namibia and South Africa. Ticks are closely related to the mites, within the subclass Acari. rDNA analysis suggests that the Ixodidae are a clade, but that the Argasidae may be paraphyletic.

The Ixodidae contain over 700 species of hard ticks with a scutum or hard shield, which the Argasidae lack. The Argasidae contain about 200 species; the genera accepted are "Antricola", "Argas", "Nothoaspis", "Ornithodoros", and "Otobius". They have no scutum, and the capitulum (mouth and feeding parts) is concealed beneath the body. The phylogeny of the Ixodida within the Acari is shown in the cladogram, based on a 2014 maximum parsimony study of amino ac
where do male ticks go to find a mate UNANSWERABLE where are these birds found? They are parasitic arachnids, are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians what sort of places do they live in? They flourish more in countries with warm, humid climates, because they require a certain amount of moisture in the air to undergo metamorphosis, and because low temperatures inhibit their development from eggs to larvae. do they face any threat? No but the population or distribution of this parasites is controlled as they spread diseases. which disease do they spread? Few are rickettsialpox, boutonneuse fever, African tick bite fever, and Q fever, Colorado tick fever, Crimean Congo hemorrhagic fever. was there any measures taken to control it's population? Predators and competitors of tick hosts can indirectly reduce the density and also by chemical like DDT are used.. who described it first? UNANSWERABLE how are they classified? Xodidae (hard ticks) and Argasidae (soft ticks), Nuttalliellidae,

Tick [SEP] Taxonomy and phylogeny
Fossilized ticks are known from the Cretaceous onwards, most commonly in amber. They most likely originated in the Cretaceous (), with most of the evolution and dispersal occurring during the Tertiary (). The oldest example is an argasid bird tick from Cretaceous New Jersey amber. The younger Baltic and Dominican ambers have also yielded examples that can be placed in living genera. The tick "Deinocroton draculi" has been found with dinosaur feathers preserved in Cretaceous Burmese amber from . Three families of ticks are described. The two large ones are the sister families of Ixodidae (hard ticks) and Argasidae (soft ticks).
