The Baja California bark scorpion is a slender scorpion with a long tail. It lives in the western deserts and wet places of North America, mainly in Baja California. It matters because it is closely related to the Arizona bark scorpion, and scientists only confirmed in 2004 that the two are separate species.1

It is often found in cool, moist places such as creek, stream and lakeside areas. It hides under tree bark, in rock crevices and in other ground cover to shelter from the daytime heat. It is nocturnal, so it is mostly active outside at night. It may occasionally shelter in homes or other buildings, but this is uncommon.1

怎样认出它

Slender body with a long tail1
Typically sand-coloured, though it can appear darker1
Exoskeleton can be yellow, light brown or gold1
Body length of about 3.8 to 7.6 cm1
Rests its tail on the ground, unlike other scorpions that hold it arched over the back. It also has a subaculear tooth at the tip of its stinger1

常被误认为： It is closely related to the Arizona bark scorpion, and their body shapes can be almost impossible to tell apart. Differences in venom and DNA are used to separate the two species. The subaculear tooth at the tip of the stinger and the way the tail rests on the ground are the main features that set it apart from other scorpions.1

毒液之力

毒液通过蜇刺出来。

它的毒液会造成什么？

It uses venom to hunt, injecting it into prey to immobilise or kill it. Each scorpion species has a unique venom profile, which is used to tell species apart. In humans, its venom may cause difficulty breathing or muscle spasms.1

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

Its venom has the potential to be fatal to humans, but the chances of this happening are low. It is not considered dangerous, and it is less of a medical threat than its close relative, the Arizona bark scorpion.1
