common bottlenose dolphin

The most studied and recognized dolphin species, bottlenose dolphins inhabit warm and temperate oceans worldwide, from coastal shallows to the open sea. Highly intelligent with large brains relative to body size, they demonstrate self-recognition, complex communication, and social learning. They live in fluid fission-fusion societies and cooperate to herd fish. A keystone indicator species for marine ecosystem health.

Rock Pigeon

Among the world's most successful birds, rock pigeons are native to sea cliffs and caves of Europe, North Africa, and South Asia but have been domesticated for thousands of years and introduced globally to every urban center on Earth. Their exceptional homing ability — navigating thousands of kilometers using magnetic fields, sun position, and landmarks — has made them vital military messengers and racing sport birds. Today, feral populations inhabit every major city worldwide.
