How do they hunt? Thread starter boosh96 Start date Jan 14, Joined Jan 8, Messages Okay, so it doesn't seem like tarantulas are able to smell or hear, and I already know that they have terrible vision. So that brings up the question-how exactly do tarantulas hunt as effectively as they do? Joined Jul 27, Messages 2, Personally, saying they hunt wouldn't feel right to me. They are more ambush predators, grabbing things that wander into their area, rather than pursuing and tracking down prey.

A tarantula's incredibly complex sensory system is, in my opinion, one of the most amazing and interesting things about these spiders. Thanks for the primer on it!

According to the Saskatchewan Science Centre, while tarantulas are molting, they can also replace internal organs — including female genitalia or stomach lining.

They can even regrow lost legs or pedipalps short sensory appendages. Tarantulas are by no means tiny, but Sewlal noted that if they are threatened, they will raise their front two pairs of legs in the air. Tarantulas primarily eat insects, though some species enjoy larger game like frogs, mice and small lizards.

According to Texas Parks and Wildlife Magazine , most terrestrial species of tarantulas are burrowers. Unlike many spider species, tarantulas do not use webs to catch their prey. They do, however, spin silk. If a tarantula lives in a place with dry soil, it will burrow into the ground and line the walls of the hole with silk to help keep sand and dirt out.

If a tarantula does not burrow, it might spin a burrow out of silk, or live under a log or rock. Sometimes, tarantulas spin a line of silk near the entrance to a burrow, which, reports National Geographic, acts as a trip wire, alerting the spider to prey that is nearing its home.

According to the San Diego Zoo , when prey comes close, tarantulas ambush it, seize it with their legs, paralyze it with venom , and then kill it with their fangs. They can also crush prey with their strong jaws. After the prey is dead, tarantulas inject digestive enzymes into the prey to liquefy the body and suck it up through their straw-like mouths.

Afterward, he rubs himself on the web, loading his pedipalps with it. If she is receptive, she will emerge from her burrow, and the male will begin a series of courtship displays, including lowering the front of his body, raising his abdomen, shaking his pedipalps, and moving back and forth, according to Sewlal.
