Abstract:. Snapping shrimp damp the shock waves they produce and use as weapons with a helmet-like structure termed the orbital hood. Here, we ask how stru

Snapping shrimp can create shockwaves strong enough to stun prey. But how do they survive each other’s blasts? USC biologist Dan Speiser and his team discovered that a special “orbital hood” — a helme...

Summary: The helmet-like orbital hoods of snapping shrimp are primarily protective and neither impair spatial vision nor make meaningful contributions to it.
