SUMMARY
Filmmaker Barny Dillarstone, known for exploring underwater environments with cameras, recently deployed a night-vision camera into London's River Thames. The footage captured two invasive species: signal crayfish from North America and Chinese mitten crabs. Dillarstone explains that these species disrupt the river's ecosystem by outcompeting native wildlife and causing bank erosion. The experiment involved a night-vision camera housed in a protective cage with bait, lowered into the murky water via a rope system.
