🧊 3D Kelp Forest Trophic Cascade: Sea Otters, Urchin Barrens and a Keystone Removal Experiment

Swim through a Blender-built giant kelp forest where sea otters, urchins, snails and reef fish follow the same food-web model as the 2D lab: remove the otters and watch urchins strip the canopy into a barren, then reintroduce them or sweep the otter mortality to find the tipping point.
