Terrifying Tarantula

Terrifying Tarantula – Photograph by Laura Lecce

Even though I named this photo terrifying, and I can understand why it might be to some people, I was so excited to see this gorgeously hairy tarantula. Even though tarantulas have fangs and are venomous, and may on a rare occasion bite causing discomfort, there has never been a death by tarantula bite (of a human). Their body hairs however can irritate the skin and cause a rash, and some people are known to be highly allergic to them. These spiders hunt at night which is when we saw this beauty, which was about the size of my hand. Squished up in a burrow they wait for unsuspecting prey (or a thin stick in this case) to walk by the entrance to their lair, and then they pounce! As is quite common in the world of spiders, male spiders are terrified of females, but of course need to get close to mate. So to make it a quicker affair, before males encounter a female they lay a ‘sperm-web’ and secrete semen onto it, rub their specialized legs into it (pedipalps), and then go on a search for a receptive female. Using female pheromones to guide him, he finally encounters a female burrow, and will tap to let her know he is there. If she likes him she will exit the burrow and he will spider-dance for her. If he has impressed her, her will get closer, hold her fangs with his legs and deposit the sperm underneath her abdomen. If she didn’t enjoy his dance she will either pay him no attention at all or attack him, and hopefully he has fast enough reflexes to get away.

    1. Hi Margaret,
      The irritating hairs is actually their defense mechanism to prevent them getting eaten. They will shed their hairs so that the animal trying to eat them will have a very irritated nose and mouth, and think twice about whether their meal is worth it.
