Gigantometrus swammerdami, commonly called the giant forest scorpion, is a scorpion belonging to the family Scorpionidae. It is native to India[1] and is the world's largest scorpionspecies at 23 cm (9 inch) in length,[2] and weighs 56 g (2.0 oz).
Description
Their bodies have colors ranging from uniform reddish brown to reddish black. Juveniles are typically reddish with a yellow telson. They have 16 to 20 pectinal teeth. Its chela is strongly lobiform. Its manus is completely covered by large rounded granulae, but lacks true carinae. Its pedipalp patella lacks a pronounced internal tubercle. Its carapace has a smooth disc in which the margins and posterior portion are granulate. Telson bulbous, and the vesicle longer than aculeus.[3]
The neurosecretions of the species are largely identified.[4][5][6][7]
Ecology
Its venom is not usually lethal to humans because it has arguably evolved to kill its prey by crushing it with its pincers and not by venom.[citation needed] This giant forest scorpion has often been seen around tropical rainforests and other types of moderately warm climates.
Specimens are collected from inside degraded or semi-degraded termite mounds, tree holes and abandoned rat or crab holes in the bunds of agricultural fields. Males are usually active during the summer season from April to July. Solitary individuals come out of their dens during that period.[8]
