Blanket Octopus: Spectacular Defense Display

The Blanket Octopus displays an impressive defense mechanism by unfurling a large web-like membrane to appear larger and deter predators. Female blanket octopuses can grow up to two meters, while males reach only about 2.4 cm, resulting in high sexual dimorphism. This misled scientists, leading to the discovery of the first male Blanket octopus only in 2002, as they were looking at the wrong size.
