Top: Science: Biology: Flora_and_Fauna: Animalia: Arthropoda: Merostomata
| The Flora_and_Fauna category is primarily for websites about living organisms, which means it is mostly about the biology of horseshoe crabs. Websites about eurypterids should be sent to Science/Earth_Sciences/Paleontology/Invertebrates. |
The Merostomata includes two distinct groups of marine organisms, the eurypterids (an extinct group that lived 200 to 500 million years ago) and the horseshoe crabs. The horseshoe crabs are also an ancient group; only 4 or 5 species (depending on who is counting) exist today.
