Jungle spider

Jungle spiders are monsters that can be found in Karamja and the archipelago east of Yanille. It is invisible on the minimap so it can be a threat to low level players who don't notice it. Jungle Spiders appear in Tai Bwo Wannai Cleanup minigame and the Jade vine maze.

Despite their appearance, and their description in the knowledge base, not all Jungle spiders are poisonous.

A level 37 poisonous variation of these is found on Ape Atoll and Crash Island and is aggressive to anyone, unless they transform into a monkey. A level 40 version is found in the Jade vine maze east of Shilo Village and is also poisonous.
