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 Tent-making Bat

<em>Uroderma bilobatum</em>, the tent-making bat, is a leaf-nosed bat in the family Phyllostomidae, distributed across Central America and northern South America, including Colombia, Ecuador, and Venezuela. It is classified as Least Concern on the IUCN Red List due to its wide range and tolerance of secondary and disturbed habitats. This bat is named for its remarkable behavior of biting through the midribs of large palm or Heliconia leaves to cause them to fold into tent-like roosts, which are used for shelter by small colonies. It typically inhabits tropical and subtropical lowland forests, forest edges, and plantations. The diet consists primarily of fruits, particularly figs, making it an important seed disperser in neotropical ecosystems. Roosting groups are typically small, composed of one male and several females. The species uses echolocation for navigation. Biological traits such as precise wing dimensions, body weight, and longevity remain poorly documented in standardized assessments, though adults typically weigh between 13 and 20 grams.
