 +Snapping or Pistol-shrimp make flashing bubbles
 The cavitation bubbles created by shrimp in stunning their prey have some surprising properties. The cavitation bubbles created by shrimp in stunning their prey have some surprising properties.
 Snapping shrimp produce a loud crackling noise1, that is intense enough to disturb underwater communication. This sound originates from the violent collapse of a large cavitation bubble generated under the tensile forces of a high-velocity water jet formed when the shrimp's snapper-claw snaps shut. A short, intense flash of light is emitted as the bubble collapses, indicating that extreme pressures and temperatures of at least 5,000 K must exist inside the bubble at the point of collapse. We have dubbed this phenomenon 'shrimpoluminescence' — the first observation, to our knowledge, of this mode of light production in any animal — because of its apparent similarity to sonoluminescence the light emission from a bubble periodically driven by ultrasound. Snapping shrimp produce a loud crackling noise1, that is intense enough to disturb underwater communication.

-Green Anoles  (lizard) live in warm climates throughout the New World. Aside from their chameleon-like ability to change colors, the males of these small, agile lizards also possess a throat fan—known as a dewlap—which they use during territorial disputes and for courtship. When courting, a male will bob his head vigorously and may even perform an action that resembles push-ups. In response, a receptive female will bob her head in synchrony with the male. +Green Anoles  (lizard) live in warm climates throughout the New World.
