The cobalt blue tarantula bite may sound alarming, but how dangerous is it really? Known for its electric blue legs and underground lifestyle, this spider is both fascinating and misunderstood. Whether you’re curious about its venom or considering one as a pet, this guide covers it all.
What is a Cobalt Blue Tarantula?
The cobalt blue tarantula (Cyriopagopus lividus) is a fast-moving, burrowing spider native to Southeast Asia. It’s best known for its metallic blue legs, which make it a popular but challenging pet.
While its body is mostly gray or brown, females display much more color than males. Males temporarily lose their bright blue hue during mating.
Where Do Cobalt Blue Tarantulas Live?
These tarantulas live in the humid forests of Myanmar and Thailand. They dig deep burrows and rarely leave them, which makes them difficult to spot in the wild.
Because of their fossorial nature, they prefer to stay hidden unless hunting or defending themselves.
How Dangerous Is a Cobalt Blue Tarantula Bite?
The cobalt blue tarantula bite is venomous but not deadly. Its venom causes sharp, local pain and inflammation that typically fades within hours. In rare cases, stiffness can last for up to two weeks.
This spider only bites if it feels threatened. It will not chase or attack without provocation. Although the bite is painful, it is not considered medically significant for humans.
Still, anyone bitten should clean the wound and seek medical advice, especially if allergic reactions occur.
What Should You Do If Bitten?
If you are bitten by a cobalt blue tarantula:
- Wash the area with soap and water
- Apply ice to reduce swelling
- Take pain relief if needed
- Watch for allergic symptoms like hives or breathing difficulty
Seek medical care if symptoms worsen.
Is the Cobalt Blue Tarantula a Good Pet?
These spiders are admired for their color but are not ideal for beginners. They’re fast and defensive and don’t like handling.
To keep one as a pet, you’ll need:
- A deep tank for burrowing
- Warm, humid conditions
- A hiding spot (like a cork log or cave)
- A steady diet of insects (crickets, cockroaches)
Avoid touching or disturbing it directly.
What Does a Cobalt Blue Tarantula Eat?
They primarily eat large insects. In captivity, crickets and roaches work well. In the wild, they may also catch frogs or small lizards. Feeding them once or twice a week is enough for adults.
How Big Do They Develop?
Their leg span ranges from 4 to 5 inches (10–13 cm). Females are larger and can live over 10 years, while males live only about 2 to 3 years.
