Asiatic elephant

Smaller than its African cousin, Asiatic elephants range across South and Southeast Asian forests and grasslands from India to Indonesia. Distinguished by their smaller ears, rounded back, and a single finger-like projection on the trunk tip. Deeply interwoven with Asian cultures, they have been used in religious ceremonies and as working animals for millennia. Endangered, with fewer than 50,000 remaining in the wild.

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.
