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.

Zebra Finch

One of the most popular cage birds worldwide, zebra finches are small, seed-eating songbirds native to arid and semi-arid grasslands across mainland Australia and the Lesser Sunda Islands. Males display distinctive orange cheek patches, red beaks, and barred flanks. Highly social, living in flocks that may number thousands in the wild, zebra finches are fundamental model organisms in neuroscience research on vocal learning, song development, and the neural basis of learning and memory.
