Vinegaroon's History at CuriOdyssey

Our vinegaroon was purchased from East Bay Vivarium in December 2016.

Fun Facts about Vinegaroons

The “giant” vinegaroon grows to 3.5 inches long, not counting tail appendage. Like all arachnids, the vinegaroon has 8 legs. The first 2 legs nearest the head are extremely long and are adapted to be used like antennae. When threatened, the vinegaroon will shoot out 85% acetic acid from a gland at the base of its long whip-like tail. The acid smells like vinegar and can be sprayed up to 2 feet away.

What do Vinegaroons eat?

In the wild, vinegaroons consume insects, worms, slugs and millipedes. At CuriOdyssey, they are served crickets and worms

How long do Vinegaroons live?

In the Wild: up to 7 years
In Captivity: average 4-7 years, although greater than 7 years has been reported

Where do Vinegaroons live?

Vinegaroons are found in tropical, subtropical and hot dry areas; in burrows, or under logs and rock piles during the daytime. Their habitat ranges from southern and southwestern United States, specifically Arizona, New Mexico, Texas, Oklahoma and Florida
