One of my favorite animals is the very rare blanket octopus. Few people have seen them firsthand. https://youtu.be/QJcXMPJ9XN8

The female has a spectacular ‘cape’ enclosing her tentacles, making her look larger to predators. She can grow >6.5ft or 2m!

The male is smaller than a walnut. He weighs 40,000x less than the female measuring 2.4cm.

Blanket octopus are the most extreme example of female vs male size discrepancy across the (non-mircoscopic) animal kingdom. #nature #science #SharedPlanet
