Checklist of Trinidad and Tobago Spiders - by family

Compiled by: Jo-Anne N. Sewlal

 

     Trinidad and Tobago boasts a rich biodiversity when it comes to spiders, being home to 50 confirmed families and another nine families assumed to be here due to our close proximity to the South American continent (separated by 14 km). This is quite remarkable for these tiny sister islands considering that there are 110 families in the world (Platnick 2011).
