Epaulard

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.

Red-billed Leiothrix

A striking babbler-like bird of South and Southeast Asian forests, red-billed leiothrixes have brilliant orange-red bills, olive-green upper parts, and vivid yellow-orange throat and breast with red and yellow wing patches. Native to the Himalayas and southern China, they have been introduced to Hawaii, Europe, and Japan from the cage bird trade. Highly social, living in noisy flocks of 6–30 birds in undergrowth and forest edge. Listed as Least Concern globally despite introduced range concerns.
