Is the bowspider poisonous?

It is slightly toxic. Strictly speaking, all spiders are poisonous, but most spiders are very little poisonous. Because it preys on its prey by venom, and the venom of spiders is mostly produced by its teeth piercing prey and other bodies.

Their venom is digestive juice, which digests food in vitro like saliva, so all spiders are poisonous. Only two kinds of spiders are nontoxic.

Among the most primitive spiders in existence, there are no poisonous glands in the arthropoda and arachnida of China Textile suborder. The former has not yet evolved, while the latter has degenerated and disappeared.
