Definition
Genus Tachypleus includes several species of horseshoe crabs native to Asian waters, closely related to *Limulus*. Often called 'living fossils,' these arthropods possess a horseshoe-shaped carapace and blue blood, essential for medical testing. They aren't true crabs, but are chelicerates, related to spiders. Genus Tachypleus plays a key role in marine ecosystems and biomedical research. Consider them the guardians of the Eastern seas! âŠī¸
