Rameshwaram parachute spider description
Named after the Indian island of Rameshwaram, this tree-dwelling tarantula has light and dark tiger-like markings on its body and legs that are typical of spiders in the genus Poecilotheria (1) (2). The Rameshwaram parachute spider can be distinguished from most other spiders in this genus by the distinct yellow colour of the underside of the front legs (2), and it differs from its closest relative Poecilotheria fasciata (the Sri Lankan ornamental tarantula) by an unbroken, narrow black band on a segment of the leg called the ‘femur’ (2). Furthermore, the underside of this species’ hind legs shows a distinct lilac colouration (2). Males tend to be smaller than females and have elongated markings on the legs (2).

British Tarantula Society:
- A category used in taxonomy, which is below ‘family’ and above ‘species’. A genus tends to contain species that have characteristics in common. The genus forms the first part of a ‘binomial’ Latin species name; the second part is the specific name.

Rameshwaram parachute spider biology
Little is known about this particular species; however, spiders of the genus Poecilotheria commonly live in well protected, small, dark cavities such as in tree holes, tree trunks, under tree bark and in house walls (3). These spiders feed primarily on insects and, unlike other spiders which utilise webs to capture prey, Poecilotheria spiders actively catch their prey, by attacking the insect from their hidden cavity and injecting paralyzing venom (3).
Female Rameshwaram parachute spiders tend to live for several breeding seasons and return to the same nest or cavity year after year (1). In contrast, males typically only survive one season (1). A single female can produce numerous spiderlings; the greatest number of offspring recorded from a single female being 52 (1).Top
Rameshwaram parachute spider range
The Rameshwaram parachute spider is found, as its name suggests, on Rameshwaram Island, an island situated just off the coast of Tamil Nadu, India, as well as on an adjacent area of the mainland (1).Top

Rameshwaram parachute spider status
Classified as Critically Endangered (CR) on the IUCN Red List (1).Top
Rameshwaram parachute spider threats
The Rameshwaram parachute spider is listed as Critically Endangered, mostly due to the destruction of the species’ natural habitat (1). Suitable habitat for this parachute spider is destroyed to make way for housing, recreational areas, other urban developments (1), and extensive rice paddy fields (4).Top
Rameshwaram parachute spider conservation
There are currently no protection laws in place to secure survival of this highly threatened species (1). The British Tarantula Society (BTS) in collaboration with the Zoological Society of London proposed to establish the Hanumavilasum temple, home to the largest colony of Rameshwaram parachute spiders, as a Spider Sanctuary (2) (5). Unfortunately, the sanctuary was never established, hampered by Indian wildlife politics and this important spider population remains unprotected (4).Top
