Chelifer cancroides, the house pseudoscorpion, is a species of pseudoscorpions. It is a cosmopolitan, synanthropic, and harmless species to humans.[1]

Subspecies

There are two subspecies:[2]

Chelifer cancroides cancroides (Linnaeus, 1758)
Chelifer cancroides orientalis (Morikawa, 1954)

Description

Chelifer cancroides measure 2.5–4.5 mm (0.098–0.177 in) in length. The pedipalps are very long,[3] measuring 7–9 mm (0.28–0.35 in) when extended. The body is teardrop-shaped and has a rich mahogany color. The abdomen has 12 segments, only 10 of which are easily visible. The cephalothorax has one pair of eyes.[1]

Reproduction

Males maintain small mating territories, few centimeters in size. When a female enters the territory, the male initiates a mating dance and eventually deposits a spermatophore, which is then picked up by the females. Fecundity is 20–40 eggs. The development from egg stage into maturity takes 10 to 24 months and involves three molts;[1] molting may involve building a silk nest.[3] The total life span is 3–4 years.[1]

gollark: There's also `peripheral.getNames()` to list connected peripherals and `peripheral.find "modem"` or whatever to find peripherals.

gollark: Or `redstone.getSides()`, which is exactly the same.

gollark: Yes, not really sure why you'd want the return value in any case.

gollark: If you want to see the table's contents, use the `textutils.serialise` function.

gollark: It means it's returning a table, and `tostring` which I believe `print` uses internally doesn't actually print their contents.
