An external fixator acts as a stabilizing frame to hold the broken bones in proper position. In an external fixator, metal pins or screws are placed into the bone through small incisions into the skin and muscle.n external fixator acts as a stabilizing frame to hold the broken bones in proper position.

Cockatoo Squid This transparent cockatoo squid (Leachia sp.), also known as a glass squid, lives in the depths of the ocean and has many adaptations to help it survive there. It retains ammonia solutions inside its body that give it a balloon-like shape and help it float.
In 2004 Japanese researchers took the first images of a live giant squid in its natural habitat, and in July 2012 a live adult was first filmed in its natural habitat off Chichi-jima.iant squid and some other large squid species maintain neutral buoyancy in seawater through an ammonium chloride solution which is found throughout their bodies and is lighter than seawater. This differs from the method of flotation used by most fish, which involves a gas-filled swim bladder.
