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.

Orca común

El mayor miembro de la familia de los delfínidos, la orca (Orcinus orca) puede alcanzar hasta 9 metros de longitud y 6 toneladas de peso, y se encuentra en todos los océanos desde el Ártico hasta el Antártico. Es un depredador apex que vive en grupos matrilineales con dialectos distintos, estrategias de caza y tradiciones culturales que difieren entre poblaciones. Algunas poblaciones se especializan en peces, otras en mamíferos marinos. Sin depredadores naturales, las orcas ocupan la cima de todas las cadenas tróficas marinas que habitan.
