Boa Constrictors have teeth that are comparatively small to their body size, because they mostly use them for gripping their prey before ingestion. Anywhere from a few millimetres to a centimetre would be a good estimate, depending on size. They don't actually kill their prey with their fangs like venemous snakes do, they kill their prey by strangling them with their body, so they don't need large fangs or teeth.
It varies from centimeters to an inch depending on species and age.
They don't have fangs - as they're non-venomous. However - they DO have approximately sixty teeth - which are up to 1/4 inch (6mm) long !
usually tarantulas fangs are at the front of there teeth like e.g. antennea on scorpions
tarantulas uses their venom inside their fangs to kill people we are alergic to them.
Mostly tarantulas are harmless to humans, but they can inflict a painful bite if provoked. The Sydney Funnel-Web Spider, which is poisonous, is not a tarantula. In addition to their fangs, tarantulas in the New World have what are called "urticating hairs", which they throw from their abdomens to fend off curious predators.
Tarantulas in the wild feed on any small animal they can get their fangs into. This includes beetles, crickets and other small insects, right up to rats, birds, frogs and even snakes or other tarantulas. In captivity most are fed on crickets, and once they are big enough, introduced to baby or "pinkie" mice/rats.
A spider lives in a web and a caterpillar is a ground species like a grub.

One type of "Fang Cap": For Halloween people put them over their teeth to make them look like fangs. Another type: They are tiny Styrofoam plugs that spider wranglers who work on movie sets use on the fangs of spiders like large tarantulas, etc.
