When you squish some spiders does blood come out
Spiders have an open circulatory system, instead of a closed circulatory system like humans, meaning their blood is not contained within blood vessels. Instead, they have a blood-like fluid called hemolymph that circulates throughout their body. Hemolymph is not as red as blood, but it does contain proteins and cells that are similar to those found in human blood. When a spider is squished, the hemolymph may leak out and appear to be blood. However, it is not true blood like that of humans and animals.
