Barnacles are marine animals that live in both shallow and tidal waters.[http://en.wikipedia.org/wiki/Barnacles]They can be found anywhere in the intertidal zone on just about any coast in the world. They are found just about anywhere.[http://www.wildsingapore.com/wildfacts/crustacea/othercrust/ciriipedia/cirripedia.htm] They can also be found glued to just about any surface. These surfaces include ships, rocks, whales, and docks.[http://library.thinkquest.org/J001418/barnacles.html] | Barnacles are marine animals that live in both shallow and tidal waters.[http://en.wikipedia.org/wiki/Barnacles]They can be found anywhere in the intertidal zone on just about any coast in the world.

Their | Their predators include [[sea stars]], [[sea snails]], some [[birds]], [[fish]] (Such as [[Sheephead]]), and [[worms]]. Also dangerous chemicals can harm the Barnacles. This can be toxic to barnacles when oil spills occur.[http://library.thinkquest.org/J001418/barnacles.html] Limpets and Muscles also invade and compete with the barnacles for space.[http://www.absoluteastronomy.com/topics/Barnacle] | ||
There are two ways that barnacles use to overcome their predators. The first and most obvious is a very fast and effecient reproductive system. This enables the barnacles to produce higher up and closer to shore, allowing them to get bigger and harder to reach from their predators. The second is a defense called "Swamping". In Swamping the Barnacles Produce a high number of offspring that all cling to one specific area. This ensures that there's a good chance that at least a few of them will survive. These are both effective strategies in defense against predators.[http://www.absoluteastronomy.com/topics/Barnacle] | There are two ways that barnacles use to overcome their predators.

Doctors and scientists are very interested in manufacturing the type of glue that a barnacle uses to attach itself to rocks and other surfaces. Research has shown that this is an extremely strong adhesive. A thin layer three ten-thousandths of an inch thick over an area of one inch can support a weight of seven thousand pounds. It can also withstand temperatures up to 380 degrees Farenheit without cracking, and it will only soften at temperatures above 6,000°F. It is also resistant to water, strong acids, solvents, and alkalies. This would be a valuable substance if we could find out how to produce it. There are a thousand ways that it could be useful for. This includes medical, construction, mililtary, and even everyday uses. | |||
