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.

Common Cone-headed Grasshopper

<em>Acrida ungarica</em>, commonly known as the common cone-headed grasshopper, is a large grasshopper in the family Acrididae. This species is notable for its distinctively elongated, conical head that gives it a slender, streamlined appearance. It typically inhabits open grasslands, meadows, scrublands, and the margins of wetlands, where tall grasses provide both food and cover. <em>Acrida ungarica</em> is a phytophagous species that feeds primarily on grasses and other herbaceous plants. Its coloration varies from green to brownish-yellow, offering effective camouflage in its grassy habitat. The species is distributed across parts of Europe and western Asia. It is assessed as Least Concern on the IUCN Red List, with no major threats identified to its populations. Biological traits of this species remain poorly documented in the scientific literature.
