Do whales poop? When a whale releases its excrement the whales poop comes out as an almost liquid form of fecal matter often in a plume-like cloud and is light enough that it does not sink to the bottom sea but floats across the top of the ocean; in some cases the excrement may also come out in chunks rather than a plume-like cloud.
Can a whale live in freshwater? Despite the fact that these marine mammals thrive in the ocean whales cannot live in freshwater environments, at least not for long periods of time.
In fact all known species of whale live and thrive in saltwater environments rather than freshwater, and there are a number of reasons for doing so. Do whales eat sharks? These marine mammals have been known to attack and eat everything from small fish and turtles to squid, seals, sea lions and even large whales. Killer whales also hunt, attack and eat sharks. The killer whale then grabs the shark and flips it over to incapacitate it by causing tonic immobility.
Can dolphin live in freshwater? Dolphins that are not considered freshwater dolphins may visit or travel through freshwater environments, but they ultimate return back to their saltwater habitat. Do whales sweat? Whales, dolphins and porpoises are marine mammals of the order Cetacea.
Because they live in water all the time, they do not have sweat glands. Rather, they depend on the surrounding water to regulate their body temperature. How do whales sleep without drowning? Fish also drink water. Speaking of whether the fish drink water, I think of whether the fish is thirsty? For example, at home, we only drink water when we are thirsty. The feeling of thirst is a bodily form that signals that we need to be hydrated.
Fish live their entire lives in water, so how can an organism living in water get thirsty? Are you hungry when there is still food in the house? The answer is not that simple. Saltwater fish and freshwater fish have different biological anatomy which leads to different behaviors in drinking water. Drinking water is just a reflex that occurs without a decision of their body. Therefore, it can be said that the whole species never thirsts. In fact, the blood salt concentration of freshwater fish is much higher than the water around it.
So if freshwater fish drink water, they have a higher risk of thinning the blood. This is why freshwater fish do not drink.
Instead, they use an osmotic mechanism. Freshwater fish absorb water through their gills and skin. In addition, they also excrete much more diluted urine to remove excess water from the body. Compared to the surrounding water, saltwater fish have much thinner blood. They are therefore always faced with the risk of dehydration.
That is why saltwater fish should actively drink water. Thanks to the special gills, saltwater fish can drink seawater, process and expel any excess salt.
A good example is salmon, which are able to migrate from salt water to fresh water. Juvenile trout are born in freshwater and undergo three major transformations before leaving their birthplace to return home to saltwater.
And most importantly, the mechanisms in their gills begin to work in reverse, removing them instead of absorbing salt from the water. As salmon mature, they have to return to freshwater to spawn, they spend a few days in an intermediate environment, also known as mudflats coastal waters or areas with exposed seabed.
Here their bodies will reverse the whole transformation process when they are young so that they can survive in fresh water. The answer, then, is species of fish capable of living in both drinking water environments. And their neighbors? Do whales, dolphins or turtles need to drink water? We all know that these creatures, like all others, need water. The point to be clarified here is whether or not they drink water from their surroundings.
Whales must replenish their bodies by drinking the water around them or by absorbing them from food. Whales are classified as aquatic mammals. They need to replenish their bodies by drinking water around them or by absorbing them from food. The whale has very large kidneys, it can excrete excess salt without losing too much water. As humans, we breathe, we lose a lot of water. The reason for this difference is that the layer of air on the surface of the ocean is filled with water vapor, so whales do not lose water when breathing.
Fishing nets and gear - trawl nets are pulled by boats, static nets hang in the water; both catch everyone and everything in their path and are a massive threat to blue whales. Vessel strikes — the number of boats on the ocean is increasing all the time. Though they are large, blue whales are relatively slow and are vulnerable to strikes by many kinds of vessels. Irresponsible whale watching — their size and fame make blue whales very popular with whale watchers, but unfortunately in some parts of the world boats are getting too close and interfering with their lives and natural behaviours.

Communication often occurs using either vocalization or body language. Some whales primarily baleen whales produce very deep low-frequency sounds commonly known as a whale song. These types of sounds are often heard during mating season when whales are looking for a partner to mate with.
Other species mainly toothed whales communicate using high-pitched frequencies in a combination of clicking and whistling sounds. These sounds can be used both for communicating with other whales in the group and for echolocation which helps them hunt and search for food.
In short baleen whales are often known for low-pitched deep sounds while toothed whales are known for higher pitched clicks and whistles. Various forms of body language can include breaching the water, spyhopping, lunging and slapping their flukes and tails against the water to communicate a variety of things such as nearby danger, a desire to play, to alert the group of nearby food and to challenge one another during mating season.
Aside from making a huge splash breaching allows whales to show off their physical prows during mating periods as well as creating a loud sound that can be heard by other whales that are below the waters surface. Spyhopping is when a whale lifts its head above the water in order to get a better observation of its surroundings. Spyhopping is believed to be used to help whales look out for predators, locate food and keep track of other whales in the area.
First slapping their flukes against they water may be the result of a hunting technique that some whales use in order to prettify or immobilize their prey before attacking and engulfing their defenseless meal.
