Both spiders and ticks are biologists to one class of spidershaped, and their structure and features of life are studied in one area of science (arachnology). They belong to the largest type of animals, which includes almost a million species arthropods, because both are close relatives, which means that they have a large number of general characteristics.
Community of ticks and spiders
The class of spidershaped combines many species, and among them can be distinguished by ticks and spiders. Despite the fact that the ticks differ significantly from most spiders, but their structure indicates that they are still arachnous: in ticks, there are also four pairs of legs in spiders, like spiders.
There is a certain similarity in the structure of spiders and ticks: both have two parts of the body, which are commonly called the headbond and abdomen. The body of representatives of both species is covered with a chitin carapace, and thanks to this fact, we can conclude that their origin and their kinship can be concluded.
If we talk about parasitic groups, then such animals usually have a huge number of special devices that provide them with the opportunity to fix on the surface of the victim (birds, mammals and so on).
Ticks, like most spiders, breathe the entire surface of the body, and representatives of large species do this with the help of trachea; and have a reduced blood system. Both species are distinguished by dioecessorism, and, as a rule, sexual dimorphism: females are usually more males.
Differences in two types
Speaking about the similarity of spiders and ticks, one cannot fail to note those moments that distinguish these two types. So, in ticks, the body segmentation does not differ in such severity as this can be observed in spiders: their headbend and abdomen are tightly interconnected, but the mouth system is isolated into an organ, called the false head. In ticks, the rotary organs are formed in different types, from gnawing to the priest-loving and even cutting, t.e. imprisoned for the ability to make a puncture and suck.
Ticks have another significant difference: these are sizes. Tick dimensions do not exceed 0.4 mm, and only a few copies reach more than 3 mm. The spiders are more impressive, and almost all of the exception are poisonous.
There is a difference and the method of nutrition of spiders and ticks: the latter are used to consuming decaying organics, juice and even the blood of other organisms, and are considered a parasitic species (although the existence of predatory ticks is recorded). Spiders, but almost everyone belongs to predators.
