Spiny orb-weavers is a common name for ''Gasteracantha'', a genus of spiders. They are also commonly called Spiny-backed orb-weavers, due to the prominent spines on their abdomen (''cf''. genus ''Isoxya''). These spiders can reach sizes of up to 30mm in diameter (measured from spike to spike). Although their abdomen is shaped like a crab shell with spikes, it is not to be confused with a crab spider. Orb-weavers' bites are generally harmless to humans. ==Species== * ''Gasteracantha aciculata'' (Pocock, 1899) — New Britain * ''Gasteracantha acutispina'' Dahl, 1914 — Sulawesi * ''Gasteracantha arcuata'' (Fabricus, 1793) - India, Sri Lanka, Myanmar, Singapore, Thailand, Indonesia, East Malaysia * ''Gasteracantha audouini'' Guérin, 1838 — Sumatra, Timor, Amboina, Philippines * ''Gasteracantha beccarii'' Thorell, 1877 — Sulawesi * ''Gasteracantha biloba'' (Thorell, 1878) — Moluccas, Amboina * ''Gasteracantha cancriformis'' — New World * * ''Gasteracantha cancriformis gertschi'' Archer, 1941 — USA * ''Gasteracantha clarki'' Emerit, 1974 — Seychelles * ''Gasteracantha clavatrix'' (Walckenaer, 1842) — Lombok, Sulawesi, Mentawai Islands * ''Gasteracantha clavigera'' Giebel, 1863 — Thailand, Philippines, Sulawesi * ''Gasteracantha crucigera'' Bradley, 1877 — New Guinea * ''Gasteracantha curvispina'' (Guérin, 1837) — West, Central Africa, Bioko * ''Gasteracantha curvistyla'' Dahl, 1914 — Togian Islands, near Sulawesi * ''Gasteracantha cuspidata'' C.
