Common Seal

가장 널리 분포하는 기각류인 항구물범(Phoca vitulina)은 북대서양과 북태평양 양쪽의 온대 및 아북극 연안에 서식한다. 성체는 최대 130kg에 달하며 바다에서 어류·오징어·갑각류를 사냥하고 해변이나 바위 위에서 쉬며 비슷한 시간을 보낸다. 크고 표정 풍부한 눈은 저조도 수중 시야에 적응되어 있다. 범고래·상어·북극곰의 중요한 먹이원이다.

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.
