Class
Common name: Horseshoe Crabs
Scientific name: Merostomata
Merostomata is a class of chelicerate arthropods that includes the horseshoe crabs. These ancient creatures are more closely related to spiders and scorpions than to true crabs. In the hobby, horseshoe crabs are valued for their role in sifting through sand beds, helping to aerate and clean the substrate. They are fascinating additions to larger tanks due to their unique appearance and behavior. However, they require spacious environments and may not be suitable for smaller or crowded tanks.
