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.

White-bellied Woodstar

A tiny woodstar hummingbird inhabiting the Andes and inter-Andean valleys from Colombia to Bolivia, white-bellied woodstars are among the smallest hummingbirds with males weighing just 2.5 g. Males display a vivid amethyst-purple gorget and white belly with green flanks. Found at forest edges and gardens from 1,500–3,500 meters elevation. Despite their diminutive size, they are aggressive and highly maneuverable, entering torpor at night to conserve energy in cold Andean conditions.
