Pannus is a genus of gypsy mites (family Gamasidae), numbering about 250 species. Their sizes vary from 30x70 microns to 7 mm.
Pannus Thickis are one of the most common representatives of the gypsy mite in the aquatic environment. They live primarily in freshwater bodies, but are also found in terrestrial ecosystems such as forests and parks. These arthropods are known for their shape and size. They have a powerful body, the anterior belly is covered with many spines, which serve for protection from predators. As pannus mature, their spines may be shed and replaced with new ones. The forelimbs of pannus are equipped with two claws, which are used to capture food and protect the tick from other predators. Pannus have a rump that helps them swim. It is also where they store their eggs. Pannus oblates are an important component of the aquatic ecosystem and should not be ignored. However, excessive use of water can lead to a decline in the numbers of these tick species, so it is important to follow proper water management practices.
