Many marine animals are ectotherms because it is too difficult to maintain an increased body temperature in water. Heat transfers much more quickly in water than it does in air thus meaning it requires a body to produce much more heat to stay at a stable temperature.
As an example - If it was 50 degrees outside, it wouldn't be very hard for you to go out with very little clothing on and stay outside for an extended period of time. However, if you jumped into 50 degree water, you would very quickly become cold and soon develop signs of hypothermia.
Marine animals avoid this by simply changing their body temperature to suit the surrounding environment. Some can keep their body temperature higher. As an example, Great White Sharks gain some of the benefits from a high metabolism. For marine mammals, the situation is a bit different. Since mammals, by nature, are warm blooded they have had to develop different ways to insulate themselves from the water. Some examples are blubber in whales and seals, and thick or waterproof fur/feathers like polar bears, otters, and penguins.
What else can I help you with?
Why are marine organisms said to literally live in a desert?
Marine organisms are said to live in a "desert" because ocean waters, especially in open ocean regions, have low nutrient concentrations similar to those found in deserts. This makes it challenging for marine organisms to find food, just like how organisms in deserts struggle to find water. However, in contrast to deserts, the ocean is vast and teeming with life in certain areas.
What type of work do marine biologist do?
Marine biologists study marine organisms, ecosystems, and their interactions with the environment. They may be involved in fieldwork, data collection, laboratory analysis, and conservation efforts to better understand and protect marine life. Their research can help inform policies and practices related to marine environments.
What is the meaning of marine biology?
Marine biology is the scientific study of organisms in the ocean or other marine bodies of water. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land,marine biology classifies species based on the environment rather than on taxonomy.
What role do zooplankton play in such ecosystems?
the niche of the zooplankton is providing filter feedings for other organisms

How do marine animals live near the surface of the ocean?
Most organisms are either directly or indirectly dependent on photosynthesis. Photosynthesis is the process where plants use the energy from sunlight to convert carbon dioxide and water into sugars and oxygen. Most organisms, not only marine organisms are either herbivores or carnivores that feed on herbivores and herbivores need plants to feed. Since the surface zone of oceans and lakes is the layer where most of the sunlight frequencies still penetrate, it is there where most plants grow. Where there are many plants there are many herbivores that feed on plants and ultimately carnivores can live there, because this is where most of there prey can be found.
Do waves affect marine organisms and where they live?
Waves affect certain marine organisms. Only the ones near the surface, they could also be affected by the tides (High tide, low tide)
How can marine organisms be classified?
Marine organisms can be classified based on various factors such as their size, habitat, and behavior. They can also be classified taxonomically based on their physical characteristics and genetic relationships. Additionally, marine organisms can be classified based on their ecological role in the marine ecosystem.
