Foca común

El pinípedo de distribución más amplia, la foca común (Phoca vitulina) habita las costas templadas y subárticas del Atlántico Norte y el Pacífico Norte. Los adultos alcanzan hasta 130 kg y pasan aproximadamente el mismo tiempo en el mar cazando peces, calamares y crustáceos que descansando en playas y rocas. Sus grandes y expresivos ojos están adaptados para la visión subacuática en condiciones de poca luz. La foca común es una fuente de alimento fundamental para orcas, tiburones y osos polares.

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.
