The yellow crab spider, [1] (Thomisus callidus), is a species of spider of the genus Thomisus . It is found in Sri Lanka, Singapore, Sumatra, Nias Island, and Java. [2] They often hide in flowers and are able to change colors just to blend in to capture preys. [3]

Spider order of arachnids

Spiders are air-breathing arthropods that have eight legs and chelicerae with fangs able to inject venom. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every habitat with the exceptions of air and sea colonization. As of November 2015, at least 45,700 spider species, and 113 families have been recorded by taxonomists. However, there has been dissension within the scientific community as to how all these families should be classified, as evidenced by the over 20 different classifications that have been proposed since 1900.

<i>Thomisus</i> genus of arachnids

Thomisus is a genus of crab spiders with almost 150 species described. The genus includes species that vary widely in their ecology, but the best known crab spiders are those species that people call the flower crab spiders, because they are ambush predators that feed on insects visiting flowers. The flower crab spiders are the species for which the popular name was coined, because of their crab-like motion and their way of holding their front legs in an attitude reminiscent of a crab spreading its claws as a threat.

Sri Lanka Island country in South Asia

Sri Lanka, officially the Democratic Socialist Republic of Sri Lanka, is an island country in South Asia, located in the Indian Ocean to the southwest of the Bay of Bengal and to the southeast of the Arabian Sea. The island is historically and culturally intertwined with the Indian subcontinent, but is geographically separated from the Indian subcontinent by the Gulf of Mannar and the Palk Strait. The legislative capital, Sri Jayawardenepura Kotte, is a suburb of the commercial capital and largest city, Colombo.
