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.
Comoro Rousette
<em>Rousettus obliviosus</em>, the Comoro rousette, is a fruit bat in the family Pteropodidae endemic to the Comoros archipelago in the Indian Ocean, primarily recorded from Anjouan and Mohéli islands. As an Old World fruit bat, it plays an important ecological role in pollination and seed dispersal across the island's native forests. The species inhabits tropical moist lowland and montane forests, roosting in caves and dense vegetation. Its range is severely restricted by the small land area of the Comoros, making it inherently vulnerable to habitat loss. Deforestation driven by agricultural expansion and charcoal production has significantly reduced available forest cover on the islands. The IUCN classifies the Comoro rousette as Vulnerable, reflecting ongoing population pressures and limited geographic distribution. It is presumed to feed on fruits, nectar, and pollen typical of Old World fruit bats, though detailed dietary studies are limited. Biological traits including precise body measurements and lifespan data remain poorly documented in the scientific literature. Conservation efforts on the Comoros islands face challenges due to limited resources, though the species benefits from some protection within national parks and forest reserves. Its survival depends on the preservation of intact native forest habitat across the archipelago.
