  Thousands of animals can kill humans.So which are the deadliest?

  That means which can probably cause the most deaths? Here are two ways to answer this question:

  ●Which animals have the deadliest poison(毒)?

  Many consider the golden poison-dart frog the most poisonous(有毒的)animal on Earth.Scientists have determined that two micrograms(微克)of its poison could kill a human.It is said that the ink in a period weighs about six micrograms.This 5-centimeter-long frog has enough poison to kill 10-20 people.

  Others think that the 5-meter-long box jellyfish is the most poisonous.In fact, its victims can die before they can get out of the water.One of these jellyfish can kill 60 adults.But in fact, these jellyfish have only caused about 100 reported deaths in the last 100 years.

  ●Which animals cause the most deaths?

  Poisonous snakes like the Russell's viper and Indian Cobra come near the top of this list.Snakes kill at least 20,000 humans world yearly.

  However, the mosquito(蚊子), a more common living things comes number one.Mosquitoes carry and spread(传播)diseases to over 700 million people every year.As a result, mosquito bites lead to over 3 million human deaths per year.That makes the mosquito, by far, the world's deadliest animal.
