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.

Eunotia serra is a distinctive freshwater diatom characterized by its curved cell outline bearing prominent tooth-like undulations along the dorsal margin. It inhabits acidic, nutrient-poor freshwater environments including bog pools, mountain streams, and oligotrophic lakes. This photosynthetic diatom is a bioindicator of acidic, oligotrophic freshwater conditions.
