Which spider has 10 legs?

No true spider has 10 legs. However, some creatures that look like spiders—such as solifuges (also called sun spiders or camel spiders)—appear to have 10 because their front pair of appendages are actually pedipalps, used for sensing and handling food, not walking. Though they resemble spiders, solifuges belong to the arachnid family and are often mistaken for them.

Why Some Arachnids Are Mistaken for 10-Legged Spiders

1. Solifuges (Camel or Sun Spiders): These desert-dwelling arachnids have two large, leg-like pedipalps at the front, making them appear to have 10 legs. They are fast, fierce hunters with strong jaws but are not venomous.

2. Sea Spiders: Despite the name, sea spiders are not true spiders and not arachnids. They are marine arthropods that live in oceans. Some species can have more than 10 legs, with leg spans reaching up to 70 cm (2.3 ft).

3. Tarantulas: On rare occasions, a mutation or injury can cause a tarantula to grow an extra leg. But under normal conditions, all tarantulas—and all true spiders—have eight legs.

4. Trapdoor Spiders: Because of their body structure and movement, trapdoor spiders can sometimes be mistaken for having 10 legs, though they also have the standard eight.
