- Horse shoe crabs are not true crabs, and are more closely related to terrestrial spiders than blue crabs.
- Often called "living fossils," horseshoe crabs have existed for more than 300 million years.
- Although their spikes and spines may look dangerous, horseshoe crabs are harmless.
- Just like other arthropods, horseshoe crabs must molt to grow. They leave their old shells behind and grow a new, larger shell.
