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.

Dictyota dichotoma is a common brown alga with repeatedly forked, flat, olive-green to golden-brown fronds forming broad, fan-like thalli. It inhabits intertidal and shallow subtidal rocky shores of temperate to tropical seas worldwide. This photosynthetic macroalga anchors to rock via a holdfast and can reproduce both sexually and asexually.
