The spinybacked orbweaver is a small spider with six spiky projections on its rounded abdomen, which look a little like a crab's shell. It lives across North, Central and South America and the Caribbean, and has been introduced to Hawaii. It is a member of the orb-weaver family, which builds round webs.1

Eziokwu

Members of the genus Gasteracantha have an unusual 19-hour circadian rhythm, so their wake-sleep cycle is neither nocturnal nor diurnal.1

Males die six days after they have transferred sperm to the female.1

The spiders often live on the edges of large colonies of Metepeira incrassata, which can contain from a few hundred to a few thousand spiders.1
