Trinidad and Tobago boasts of a rich biodiversity as it pertains to spiders, being home to 50 confirmed families with 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).
