Goliath birdeater - Theraphosa blondi
The Goliath birdeater spider is the second-largest spider in the world, in terms of legspan, and probably the largest in terms of mass. Despite its name, it doesn’t often eat birds in the wild, if only because the webs of this species are upon the ground. Reptiles (including venomous snakes), amphibians, and small rodents are caught far more often.
These spiders are tarantulas, and have the skin-piercing fangs and urticating hairs of that genus. 
However - unlike most other tarantulas - the males of this species don’t have “tibial spurs” (used to keep females in place while mating). Their pedipalps are sharpened at the end in a “palpal bulb”, which is used to hold both the females and prey.
