Happy #WorldHorseshoeCrabDay!
 These spinning #horseshoecrab (Limulus polyphemus) embryos are developing inside their eggs, just weeks away from hatching. Despite their name, horseshoe crabs are closer relatives of spiders and scorpions than crustaceans.

The pericardium forms as a distinct structure during heart formation - Nature Communications
The developing heart integrates several progenitor cell types. Here they show that the pericardium enveloping the heart develops among cells that form the mesothelium around inner organs and body cavities, distinct from the classic heart field.
