Common cuttlefish (Sepia officinalis), Arrábida National Park, Portugal. The common cuttlefish is one of the largest and best-known cuttlefish species. They are a migratory species that spend the summer and spring inshore for spawning and then move to depths of 100 to 200m during autumn and winter. They only have a lifespan of 1–2 years and have many predators including sharks, dolphins, seals, fish, and cephalopods which includes other cuttlefish. During the day, most cuttlefish can be found buried below the substrate and fairly inactive. At night however, they are actively searching for prey and can ambush them from under the substrate. Cuttlefish are carnivorous and eat a variety of organisms including crustaceans (crabs and shrimp), small fish, molluscs (clams and snails), and sometimes other cuttlefish.

Mauritius kestrel (Falco punctatus), Ebony Forest Reserve Chamarel, Mauritius. In 1974, this Mauritius endemic was the rarest bird in the World. Due to ground-breaking conservation work the population rose to 800, but has now slumped to possibly 400 birds. In 2023, the Government of Mauritius declared the Mauritius Kestrel as its national bird.
