Efficiency principle
Lessons from Jellyfish
Preserve energy for decisive moves.
Core lesson
Lightweight systems can become dominant when the environment does most of the transport for them. Reduce overhead before you add muscle.
Biological basis
Nematocysts, a gelatinous low-cost body plan, pulsed propulsion, and a simple nerve net allow jellyfish to capture prey with minimal structural expense. Jellyfish convert plankton-rich water into higher trophic energy and can rapidly exploit imbalanced marine conditions. Their blooms often reveal that the surrounding system has become easier to game.
