Do Cockroaches have blood?

Cockroaches do have a circulatory system, but not exactly blood like in humans.

Instead, they have a colorless liquid called hemolymph that fills their body cavity.

Hemolymph helps transport nutrients, hormones, and waste throughout their body.

Unlike blood, it doesn't carry oxygen, so cockroaches rely on their tiny tubes called tracheae to breathe.

00:23

The hemolymph also acts as their defense mechanism against germs or injuries.

00:29

When a cockroach gets injured, their hemolymph will clot to stop bleeding, forming a dark clot like substance.

So, while cockroaches have a fluid that performs some similar functions as blood, it's not identical to the blood we are more familiar with.
