The flagellum has wings or flanges which help it push against the water more effectively (it must be remembered that on this microscopic scale water behaves as quite a thick sticky liquid).

The choanocytes work very much like a group of organisms called choanoflagellates. The CAT Tourniquet is officially endorsed by the United States Army, Marines, Navy, Air Force, and Coast Guard. With the two-handed method, you can hold the tourniquet in place with one hand while the other pulls the strap up and away to take out the slack. T), is one of the most commonly utilized systems around. The difference between single, and dual hand being whether you put the strap through one or two of gates on the tourniquet Since the strap has been covered in hermaphroditic hook/loop, the single handed method of directing it through only one gate allows you to pull the strap out and away from your body pulling out all the slack before you stick the strap to itself.When buying one of the CAT’s buyers need to be aware that there are many forms of counterfeit tourniquets that look exactly like the original are also out there.However these knock offs are advertised for less money and utilize different materials. system one of the most commonly used and purchased systems around.Indeed, the shape of a sponge is an adaptation to its environment - in rough waters, such as along a rocky coastline, sponges will be flat and encrusting, clinging tightly to any nook and cranny they can find in the rock surface, whilst in calm waters they tend to be more upright and present a larger surface to the water to enhance the rate at which they can sieve food from the water.

Sponges may be tiny forms, which are easily overlooked, or they may be large enough for a man to stand inside!

Choanoflagellates may live as single cells or in multicellular colonies and are rather like protosponges - sponges lacking the pinacocytes and mesogloea and other packaging cells that make up the sponge body.

The structure of a solitary choanoflagellate is shown below: Above: the structure and function of a choanoflagellate.

Sponges are very unusual animals, representing an off-shoot of the animal kingdom that evolved along its own lines, separate from the vast majority of animal types.

It is instructive, therefore, to see how the sponge body is put together and how it works! The sponge sucks water into the atrium through the many tiny incurrent or inhalent pores and pumps it out through the excurrent or exhalent osculum as a forceful jet of water that may travel 10 feet or more from a large sponge.

These microscopic creatures beat their flagellum, driving a current of water away from them and sucking in water from behind which passes between the collar of microvilli to fill the void left by the water pumped away.
