Mermaid's Wine Glass

Acetabularia acetabulum

Family: Polyphysaceae

📍 Mediterranean and Eastern Atlantic

Ask Finn

One of the most extraordinary organisms in biology — a single giant cell shaped like a wine glass on a slender stalk. Each 'plant' is a single cell that can grow to 10 cm. Famous in cell biology research. In aquariums it anchors in sand and is a remarkable conversation piece. Prefers cooler, calcium-rich water.
