In a scene Bruce is seen spraying something while working on his bed. He sprays a bottle of liquid onto a root like growth on a rock. What is the growth? Was this addressed in the screenplay? Throughout the movie wood, and algae (some sort of growth on the rocks) are seen fading in or out of the scene.
What is the relevance of showing wood and the growth in the screenplay? Because his father works on jellyfish, starfish, sea cucumbers, and lizards (to be able to sustain toxicity) only.
