Common Blanket Octopus

The common blanket octopus (<em>Tremoctopus violaceus</em>) is a remarkable pelagic cephalopod mollusc classified as Least Concern on the IUCN Red List, with records indicating its presence in Asian waters, including around Taiwan. The species exhibits extreme sexual dimorphism: females can reach lengths of up to two meters when the cape-like webbing between their dorsal arms is extended, while males are tiny, reaching only a few centimeters. The distinctive webbing, which resembles a flowing blanket, is thought to serve as a defense mechanism, being extended to confuse or deter predators. Females are also known to detach and wield tentacles from the Portuguese man-of-war, to which they are immune, using them as defensive weapons. <em>Tremoctopus violaceus</em> typically inhabits open oceanic waters across tropical and subtropical seas. Biological traits of this species remain poorly documented in the scientific literature.

Golden Eagle

Among the most powerful and widely distributed raptors in the world, golden eagles have wingspans reaching 2.2 meters and inhabit mountainous terrain across the Northern Hemisphere. Supreme aerial hunters, they use soaring flight and steep dives at speeds over 200 km/h to capture rabbits, hares, ground squirrels, and occasionally young deer and foxes. In many cultures they have been central to falconry traditions spanning millennia.
