Biological Adaptation Assignment

Chad Walker 1/25/12 Bio 151 MW 4:00-5:15 biological Adaptation Assignment Biological fitation is necessary for a species to increase their fitness in an environment. As organisms face divergent environmental challenges they must be adapted to develop contrasting phe nonypic traits over while to respond to the conditions. One example of an organism that ass adapt to different extreme environments would be the diddly-shit shark. Bull sharks may seem like a regular(prenominal) shark because they are most often seen in leatherneck habitats, but they can survive elsewhere. What I find particular(a) about the tinkers dam shark is its ability to live in both marine habitats and freshwater habitats. In general, being able to survive in both habitats is very uncommon for sharks. aquatic organisms rely heavily on a process called osmoregulation that allows them to make homeostasis of water contentedness within their personate. Without going into alike much detail on the specifics of osmosis and osmotic pressure, this process allows the organism to note their internal fluids from puddle as well as diluted or too concentrated. So you may be asking yourself, how does this apply to the diddley shark?

The arrange is that the bull shark over conviction has adapted its dead body to be able to date the amount of salinity that its body gets rid of allowing it to live in waters of different salinities. nautical organisms have a soaring level of salt in their body so that the ocean doesnt dehydrate them because it is a hypertonic solution. Due to the circum stance that sharks can increase or decrease ! the content of salt in their blood allows them not to take in too much water when they transmigrate into freshwaters. Sharks are known to be fierce predators of the sea, and with the capability to gauge into freshwater it makes their hunting case very vast. While other(a)(a) sharks could have difficulty finding nourishment at sea, the bull shark may roam into rivers and estuaries to consort on organisms other sharks cannot hunt.
