Can a hammerhead shark live in freshwater
Second, most shark species can only survive in brackish or saltwater, so freshwater lakes and rivers are typically out of the question for animals like great white sharks, tiger sharks, and hammerhead sharks.

How do Greenland sharks survive the cold
Trimethylamine N-oxide (TMAO) and urea, which act as anti-freeze and stabilize proteins in their bodies to prevent internal ice crystal formation, are found in high concentrations in their tissues, allowing them to survive in extremely cold temperatures.
Are Greenland sharks friendly
Although they are big and powerful enough to easily hurt or kill a person if they feel threatened, history has shown that greenland sharks are particularly non-aggressive.

Why is the Greenland shark toxic
According to a 1991 study published in the journal Toxicon (opens in new tab), unprocessed Greenland shark meat contains high levels of trimethylamine oxide (TMAO), which during digestion transforms into the poisonous trimethylamine (TMA) compound.
Do Greenland sharks eat humans
Although such a large shark could easily consume a human swimmer, the likelihood of attacks on humans is very low, and no cases of predation on people have been verified. The sharks have frequently been seen gathering around fishing boats. It also scavenges on seals.
