Sharks excrete waste out of the same hole as their urinary and reproductive tracts. This is called the cloaca. The cloaca is located at the rear underside of the shark between the pelvic fins where the it's tail starts. Unlike what most people would expect poop to look like, a shark's poop is actually a soupy liquid anywhere from a brown to greenish brown color. Shark poop disintergrates quick in water. With a quick swish of its tail the pelvic fins flare out and the shark returns its fully digested prey to the sea! It looks like a big cloud in the water.

What is does cold blooded mean?
Cold bloodedThe term cold blooded refers to the way in which the bodily temperature changes with the environment. There are three main areas of thermoregulation under the umbrella term cold bloodedness.
- Ectothermy - this refers to creatures that control their temperatures by external means, such as the sun, flowing air or water.
- Poikilothermy - this refers to the creatures who's body temperature rises and falls with the surrounding environment. These creatures would be cold in cold areas and hot in hot ones, changing as they move between them.
- Bradymetabolism - this refers to creatures who have a high active metabolism and a low resting metabolism. These creatures can undergo dramatic changes in their metabolic rate, depending on food availability and temperature. This allows creatures, such as those who live in the desert, able to shut down their body's and approach a near death sate, to survive harsh desert winters, until favourable conditions return.
Only a few creatures fall into all three categories, or use more than one method to control their body temperature. Most creatures rely on one type of thermoregulation to survive, such as snake and lizards lying on rocks, or insect vibrating their muscles in one place to keep warm.
It was originally thought that cold blooded creatures were incapable of controlling their bodily temperatures. It is now known that this is not the case and the term is therefore outdated in scientific content today.
The term warm blooded refers to the way in which creatures keep their body temperature at a constant level.
Unlike cold blooded animals, warm blooded animals tend to fit into all three categories, some only into two. This means that these warm blooded creatures uses many methods to regulate a steady body temperature.
Within the past thirty years scientists have found that some animals uses thermoregulation characteristics from both warm and cold blooded categories.
Bats and some small birds have been found to be both Poikilothermic and Bradymetabolic. For these and other creatures a new category was made, heterothermy (hetero meaning two and thermo meaning temperature).
Although the terms cold blooded and warm blooded are said to be outdated in terms of scientific accuracy, they are still widely used and understood as the regulation of temperature in organisms.
All animals communicate to one another is some way. Sharks mainly communicate is the way they swim, how their movements are articulated, for example, when they are preparing to attack, they circle.

How much are mako sharks teeth worth?
Nothing, it is illegal to trade in shark teeth or products.
==============================================
I am not finding anything that indicates it is illegal to trade in shark teeth or shark products. The U.S. and other countries have banned shark finning where the shark's fins are cut off and the rest of the body is tossed away - but that has not banned shark fishing. The sale of imported shark fins is not necessarily banned by the same countries that ban finning. I also cannot find anything that shark products are banned everywhere. That is a country-by-country issue. In the US, some states - but not all - have banned the sale of shark fins. So you need to check your local and national laws.
Now back to the teeth. The value of the teeth will really depend upon size and condition. You can look at sites that are selling them to see what they are asking. You should definitely do more research.
What do you do if a shark attacks you when you are scuba diving?
Be taken out of the water because your wound will attract more sharks, when out of the water put a cloth or towel around the wound and be taken to the hospital by someone or else you could die of blood loss........ I think
anyway your more likely to be attacked by cows than sharks and blood loss is dependant on the wound you have received and a shark won't attack with reason such as there , hungry , feels threatened and can smell blood and if you thing that the sharks are miles away they cant smell my blood then your gonna die sharks can smell miles away from the source of the blood and can swim quite fast
yes it is a invasive animal

How can a killer whale kill sharks?
An octopus may eat a shark by simplying wrapping it's tentacles around said shark and eating it, first injecting it with venom. However, this may be hard, as I do not think octopi have teeth. But not all octopi have the same venom, so only one species may be able to kill a shark that way.
