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.

Common Waxbill

The most widespread waxbill in Africa, common waxbills are native to sub-Saharan Africa but have been introduced across the Iberian Peninsula, Brazil, Hawaii, and several Atlantic islands, becoming one of the world's most widely distributed cage bird escapees. Small, lively finches with red bills and a red stripe through the eye, they inhabit rank grasslands and areas near water. Highly gregarious, often seen in large mixed flocks with other estrildids.
