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.

elk

Also known as the red deer, elk are among the largest members of the deer family, with antlered males reaching up to 240 kg. Found across temperate forests and grasslands of Europe, Asia, and North America, where populations were historically separated as distinct subspecies. Males shed and regrow their antlers annually, engaging in dramatic roaring contests during autumn rut. An important game and conservation species across its range.
