Blaue Federlibelle

A medium-sized damselfly of still and slow-flowing freshwater habitats across Europe and western Asia, blue featherlegs are named for the striking feathery tibia fringe on the males' hind legs, waved during courtship displays. Males display pale blue coloration while females are olive-green. They perch on emergent vegetation and are a good indicator species for water quality in riverine habitats. Populations have declined locally due to water pollution and agricultural intensification.

Grosse Tümmler, Grosstümmler

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.
