Pseudo Scorpion and the Beetle by Veronica Smith on Prezi
Pseudo Scorpion catching a ride on the beetle Commensalism- A relationship in which one species benefits and the other is neither helped. The Journal of Arachnology – SYMBIOTIC RELATIONSHIPS the wing-covers above (of pseudoscorpion) belong to genera or elytra of beetles. The harlequin beetle/pseudoscor- pion relationship has even been presented as ob? ligate symbiosis in which the pseudoscorpions live exclusively on the.
Also like spiders, many pseudoscorpions use venom to subdue their prey, which includes mites and other tiny arthropods. Their venom glands are in their modified pedipalps, with openings in the tips of one or both of the fingers of their claws.
Pseudoscorpions also have pretty strange reproduction. Males deposit a spermatophore a package of sperm on the ground, which a female must then pick up and insert into her reproductive opening. A female Arctic pseudoscorpion, Wyochernes asiaticus, with her brood pouch.
Although I would like to think the little pseudoscorpion in the photograph below enjoys reading, what they really like about books is the booklice that sometimes live in them.
Sean McCann Finally, pseudoscorpions are hitchhikers! To overcome this obstacle, they hitch lifts on other organisms — usually larger arthropods like beetles and flies. This particular kind of symbiosis — in which the individual doing the carrying is apparently unharmed — is called phoresis. Some pseudoscorpions are stowaways under the elytra of comparatively gigantic harlequin beetles, and feed on phoretic mites and find mates while they travel.

This bird moves about in the pastures, and follows livestock such as cattle and horses. The cattle egret eats up the insects hiding under vegetation close to the grounds, which get stirred up when the cattle walk through them. Orchids Growing on Branches of Trees Orchids belong to a family of flowering plants that form a commensal relationship with the trees.
It is a well-known epiphytic plant that grows on the branches or trunks of other trees. Orchids are usually found in dense tropical forests. They form their base of attachment on the branches of trees, and benefit by getting adequate sunlight and nutrition that flows down the branches. The orchids do not grow to a large size, and thus the host tree is not harmed in any way.
Remora Fish and Sharks The remora, also called suckerfish, belongs to a family of ray-finned fish. It is a small fish growing up to a size of 1 to 3 feet. The remora forms a special relationship with sharks and other sea organisms like whales and turtles. It has special suckers attached to its fins. It attaches itself to the bodies of sharks, and uses the shark for transportation as well as protection from its predators.
It also eats up the scraps of food that are left over when the shark eats its prey. Pseudoscorpions and Beetles Pseudoscorpions are scorpion-like insects that usually grow to less than one centimeter in length. They are different from other types of scorpions in the way that they do not have stingers.
Some species of the pseudoscorpions hide themselves under the wing covers of large insects like beetles. This gives them protection from their predators, and also provides them a means of transportation over a larger area. Because of its small size and lack of sting, it does not harm the beetle in any way.
