10Special Adaptations

I have one large claw that I uses to snap My claw closes so fast that it creates a “bubble” This bubble shoots through water at 60+ mph The bubble also reaches over 25,000 degrees Fahrenheit The bubble implodes and shocks or kills any nearby creature

11Bubbles?!

I shoot a special kind of bubble called a cavitation bubble Cavitation bubbles were first investigated in 1916 by Lord

Rayleigh of the British Royal Navy Cavitation bubbles can reach 25,000 degrees Fahrenheit They can also create 14,000 pounds or force per square inch The bubble only grows to about 1/8 of an inch in size This happens in one millionth of a second I am the only natural animal to create cavitation bubbles I was monitored in 40,000 frames per second to see the bubble

collapse
