Nosy Boraha, also known as Sainte-Marie, is an island off Madagascar's east coast, covering 222 km² with a population of about 30,000. The main town is Ambodifotatra. Famous for its natural beauty, whale watching, and rich history, the island is known for its preserved, authentic charm.

The comet moth, or Madagascan moon moth (Argema mittrei), is a large, striking moth native to Madagascar's rainforests. Known for its vibrant yellow and red tail, the species is endangered in the wild due to habitat loss but is bred in captivity. Adult moths cannot feed and live only 4 to 5 days. Males, with a wingspan of 20 cm and long feathery antennae, differ from rounder-winged females. The moth spins silk cocoons, and its unique defense mechanism includes ultrasound absorption to evade bats' echolocation, making it nearly invisible to predators.

The aye-aye (Daubentonia madagascariensis) is a nocturnal lemur native to Madagascar, recognized for its unique foraging method known as percussive foraging. It taps on trees to locate grubs, gnaws into the wood with its rodent-like incisors, and extracts prey using its elongated, thin middle finger. As the largest nocturnal primate, the aye-aye occupies a woodpecker-like niche in the ecosystem. Despite its odd appearance and habits, the aye-aye is a crucial part of Madagascar's biodiversity, though it is currently classified as endangered due to habitat loss and hunting.
