Bacillus thuringiensis is a gram-positive, spore-forming soil bacterium in the family Bacillaceae, widely known for producing crystalline protein toxins (Cry proteins) that are insecticidal. It is globally distributed in soils, plant surfaces, and insect habitats. It is extensively used in biological pest control as a safe alternative to chemical insecticides.

European otter

Sleek semi-aquatic mustelid found along clean rivers, streams, and coastlines across Europe and Asia. European otters can reach 1.3 meters in length and are highly skilled fish hunters, using sensitive whiskers to detect prey movements. Requiring unpolluted water with abundant fish, they are an indicator species for freshwater ecosystem health. Once nearly extinct in Western Europe from hunting and pollution, populations have recovered significantly following water quality improvements.
