What animal can never get sick?
SharksSharks are the only animals that almost never get sick: they are immune to almost every known disease. Their body frames are not made up of bones – they are made of cartilage, the tough, fibrous tissue that shapes our noses and ears.
Which animal has the best memory?
DolphinsSorry, elephants: Dolphins have taken the top spot for best memory, at least for now. New experiments show that bottlenose dolphins can remember whistles of other dolphins they’d lived with after 20 years of separation.
Are Crocodiles immune to disease?
Animals such as crocodiles and alligators living in polluted environments have evolved a strong immune system against cancer development. Gut bacteria in these animals produce one or more antitumour molecules to thwart cancer.
Which animal has best immune system?
ostrichesAs such, ostriches have survived and evolved with one of the strongest immune systems in the animal kingdom. They can live up to 65 years in harsh environments and withstand viruses and infections that most animals cannot.
