In the process of their investigation, Cruickshank & Skews developed a full-scale model of the head and a portion of the body of a Diplocaulus, constructed from balsa wood and modelling clay. The model was placed in a wind tunnel , and subjected to several tests to determine drag, lift, and other forces experienced by the head in different ...

A chameleon launching its tongue at its prey. Chameleons, frogs and some lungless salamanders have tongues that act like a tethered projectile. In frogs, the tongue is attached at the front of the mouth and rotates about this attachment as it flips out (thus the top of the tongue at rest becomes the bottom when extended).

The majority of insect material is inside of the endocuticle. The cuticle provides muscular support and acts as a protective shield as the insect develops. However, since it cannot grow, the external sclerotized part of the cuticle is periodically shed in a process called "molting".
In other locking and compliance applications, the body of the Kubotan can be used to create pain. A typical pain compliance technique involves seizing an attacker's wrist and sealing both hands around it with the length of the Kubotan laid across the radius bone. Downward squeezing pressure is applied to the bone to take down the attacker.
Cadaveric spasm may affect all muscles in the body, but typically only groups, such as the forearms, or hands. Cadaveric spasm is seen in cases of drowning victims when grass, weeds, roots or other materials are clutched, and provides evidence of life at the time of entry into the water.
