Animals (and plants) that live in an aquatic environment over time have become suited to their habitat. To other animals, this would be a problem, you may notice if you stay in the bath or swim underwater for a long period of time that your hands and feet become wrinkled. This is because osmosis is occurring between you and the aquatic environment.</p><p>The higher concentration in the external environment means that the concentration gradient of osmosis must even out, therefore the cells in our hands and feet become turgid (a higher than normal concentration of water). With this in hand, aquatic animals must perform <a href=https://www.biologyonline.com/dictionary/osmoregulation data-wpel-link=internal rel=follow>osmoregulation</a> to ensure that their body’s internal environment remains at its optimum level. Take note that <a href=https://www.biologyonline.com/dictionary/osmosis data-wpel-link=internal rel=follow>osmosis</a> will always occur until there is an equilibrium between the internal and external environment (isotonic concentration). Our genomes’ are used to dry environments, so this deviation from our body’s norm can indeed indicate that we are less suited to surviving in a water environment because we are not adapted to do so anymore, unlike our distant ancestors.</p><p>In regards to organisms in a freshwater habitat, they face the problem of continuous osmosis of water into their bodies, because their body is hypotonic in comparison to their external environment. This means that water will continue to diffuse into the fish until there is an isotonic concentration between the two environments. Since the fish would not be able to operate with such a high concentration of water in their system, evolutionary adaptations have overcome this problem. The kidneys which deal with the uptake of water are suited to their function, as the glomerulus’ of the kidney has a large surface area to reduce the concentration of water in the blood. As these kidney tubules allow a large scale movements of ions out of the bloodstream, the organism needs to reabsorb some important ions such as salt back into the bloodstream via active transport.</p><p>You can relate this osmoregulation to the way glycogen is stored in the kidney of humans, as the homeostatic controls involved with this area are there primarily to ensure that the conditions inside the organism are suited to the demands put upon it. Excess water within such an organism would damage the internal organs of it beyond repair by damaging the cell membrane and organelles due to the pressure caused by the water.</p><p>The opposite problem exists in animals that live in the ocean, where the salty water means that water is at a lower concentration than most organisms. The result here is that the organism is hypertonic to its external environment (has a higher water concentration), and must re-absorb water to remain in a healthy state. Evolutionary adaptation has also favoured these animals, and the kidneys have been anatomically altered over time to ensure the long-term survival of such organisms. The glomeruli in such organisms have a much smaller surface area, because the need to excrete ions into its external environment is not as extreme, because most water needs to be retained for survival, unlike freshwater organisms. Little salt needs to be re-absorbed due to the fact the salt-water environment can be drunk, and therefore is not as scarce as it would be for a freshwater organism.</p><p>The key point is that these organisms need to maintain an optimum water concentration in their internal environment to continue to function normally and optimally.</p><p>In more extreme environments, such as the desert, water is scarce and water must be stored in times of need, hence a camel humps.</p><p>Much water can be lost via sweat, under extremely hot weather or strenuous exercise<br> Excretion via urine and faeces also accounts for much of our water loss<br> Water is also required by many of our biological processes, and is, therefore, an exhaustible resource for these continuing processes.</p><p>Behavioural adaptations come into play here, as some species, such as the kangaroo rat lay in long periods of dormancy when the weather is hot, which would result in the rat losing more water through respiration than it can afford. The rat lays dormant underground in moist conditions where the concentration in water in the air and the rat’s lungs are at their minimum, therefore the least amount of water is lost to the external environment.</p><p>All these adaptations are designed for the organisms to survive more tolerably in their present habitat, and without these evolutionary changes, some of the species on the planet may not have survived to this point.</p><p> </p><div style="text-align: center; vertical-align: top; padding: 10px; border: 1px solid #e2e2e2;"><iframe src=https://www.youtube.com/embed/h87ri4qzqVA width=560 height=315 frameborder=0 allowfullscreen=allowfullscreen></iframe></div><div style="vertical-align: top; padding: 10px; border: 1px solid #e2e2e2;">Credit: <a href=https://www.youtube.com/channel/UCqNfvgVSYunXkQY75JoI6wQ data-wpel-link=external target=_blank rel="nofollow external noopener noreferrer">Meritnation</a></div><p> </p> <script>if(window.qmn_quiz_data===undefined){window.qmn_quiz_data=new Object();}</script><script>window.qmn_quiz_data["129"]={"quiz_id":"129","quiz_name":"Animal Water Regulation - Quiz","disable_answer":"0","ajax_show_correct":"0","progress_bar":"1","contact_info_location":"1","qpages":{"2":{"id":"2","quizID":"129","pagekey":"lp8LvinE","hide_prevbtn":"0"}},"skip_validation_time_expire":"1","timer_limit_val":0,"disable_scroll_next_previous_click":"0","disable_first_page":0,"enable_result_after_timer_end":"0","enable_quick_result_mc":"0","end_quiz_if_wrong":0,"form_disable_autofill":0,"disable_mathjax":0,"enable_quick_correct_answer_info":0,"quick_result_correct_answer_text":"Correct!
