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.

Manx Shearwater

A medium-sized seabird of the North Atlantic and North Pacific, Manx shearwaters are renowned for their extraordinary navigation abilities. They travel up to 1 million kilometers over a lifetime, migrating annually between breeding colonies on North Atlantic islands and wintering grounds off South America. Their stiff-winged shearing flight just above wave surfaces is characteristic. One individual lived for over 55 years, one of the longest-lived wild birds recorded.
