Invertebrates Flora Botanical gardens Civil societies The following list is of spiders recorded in Sri Lanka, a tropical island situated close to the southern tip of India.

Spiders (order Araneae) are air-breathing arthropods that have eight legs and chelicerae with fangs that inject venom.

Anatomically, spiders differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax and abdomen, and joined by a small, cylindrical pedicel.

In all except the most primitive group, the Mesothelae, spiders have the most centralized nervous systems of all arthropods, as all their ganglia are fused into one mass in the cephalothorax.

This checklist was made by the Association for Conservation of Environment and Arthropods Sri Lanka, and encompasses a wide variety of referenced journals.
