Ants, and insects in general, don’t have hearts like humans have hearts, but they do have an organ called a dorsal vessel that pumps something called hemolymph, which is similar to blood in humans. The dorsal vessel looks like an elongated tube and is surrounded by a few small muscles.
Ants do not have a closed circulatory system with a vein system and arteries as humans do. They have an open circulatory system, so there are no veins to pump anything through. Instead, the dorsal vessel pumps the hemolymph around by splashing the ants insides with nutrients, hormones, etc. This is a great oversimplification, but hopefully, you get the idea.
- The largest ant colony ever found was 3750 miles long.
- Ants move an estimated 50 tons of soil per year per square mile.
- All worker and queen ants you see are female. Male ants actually have wings and don’t live long after mating.
- Some female ants can clone themselves and don’t require a male mate.
- Ants can live up to 30 years.
