Mites are small, often microscopic in size: the smallest is about 0.1 mm(0.004 inch) in length and the largest about 6mm (0.25inch.) They usually have four pair of legs. Unlike insects, with bodies divided into head, thorax, and abdomen, the arachnid body is ancestrally divided into two functional units, the prosoma (the first six body segments) and the opisthosoma (the remaining segments). The body of a mite is further modified in that these original units are fused. A secondary subdivision separates the first two body segments into a structure termed the gnathosoma, specialized for feeding, and the remainder of the body, termed the idiosoma, containing organs of locomotion, digestion, and reproduction. Most mites show no evidence of external body segmentation, other than the serial appendages. The gnathosoma bears the first two pairs of appendages, the chelicerae, which may retain the ancestral chelate, or pincer-like form, or may be highly modified as stylets for piercing and sucking; the pedipalps, which may be almost leglike, are strongly modified for grasping prey or attaching to a host or highly reduced. The anterior idiosoma typically bears four pairs of walking legs, the first pair of which may be modified as antenna-like, sensory structures. Legs may also be modified for attaching to a host.
They live in a range of habitats, including brackish water, fresh water, hot springs, soil, plants, and they live in humans. They also may live in the nasal passages, lungs, stomach, or deeper body tissues of animals. They are found in everyday living enviroment
Sensory structures on a mite are found on the body , the palps, and the legs. These sensory structures are seta like and help to detect relative humidity, heat, and CO2. It also helps locate and identify other mites at all taxonomic levels.In general, they breath by means of tracheae, or air tubes, but in many species, respiration takes place directly through the skin.
Dust mite eggs are cream-colored and covered in a sticky substance so they are able to attach to substrates. The number of eggs laid by dust mites depends on the species. For example, American house dust mites produce around 30 eggs over one month, while European house dust mites lay 80 eggs over 45 days. Either one single egg or groups of three to five eggs are laid each day. Eggs hatch after two to eight days
Mites eat plants and animal substances, decaying organisms. The way they eat is that they suck out their innards with a retractable needle in the middle of a round mouth.
Mites are parasite that feed on animals and the human body. If mites was extinct they wouldn't be able to affect people or animals.
Their populations will be stable because the mites predators will still feed off other animals such as (spiders: millipedes, Ants: fungus, birds)
The prey that the mites eat on will reproduce and keepgrowing because the mites wouldn’t be able suck the juice from plants and fungus.
