A family of extinct sea creatures called crinoids that lived on the ocean floor and had a stem-like structure with feathery arms.
From Greek 'batos' (thorny or prickly) and 'krinos' (lily), combined with the scientific suffix '-idae' (family). The name describes their spiky, lily-like appearance.
Batocrinids were nature's underwater chandeliers—they'd anchor themselves to the seafloor and wave their feathery arms to filter-feed on tiny plankton, creating an alien garden in ancient oceans.
