Imagine taking a voyage to the deepest part of the ocean. What types of thing would you expect to see? Would you see familiar animals and plants or find strange and new ones?
Scientists keep looking for new species and new facts
Diving deep in the ocean
The deep ocean, 1,000 meters below the surface, is freezing cold.
What's worse, the water pressure can harm you if you don't have protective devices on. Therefore, deep divers wear special diving suits to protect themselves from the water pressure. ，some of which have robot arms that can collect samples of water, soil, and small animals underwater.
Using satellites for tracking
Satellites up in space can help to track sea animals travels in the ocean. Scientists attach some e animals with electronic sensors to study them. Then, a satellite can track the signal from the sensor attached on the animal's fin or back., Besides, scientists can use this signal to predict the animal's future movements.
What types of animals are in the ocean? How many are there? Oceanographers studied and counted animals for ten years to discover the answers. They looked at all the world's oceans from the North Pole to the South Pole. They counted more than 30,000 species in more than 30 million records. More than 6,000 new species had never been seen before!
However, not all the animals have been discovered.
There are many more surprises to come!
A. Counting sea animals
B. Living deep underwater
C. The more they explore, the more they find
D. It shows when, where, and how the animal travels
E. For really deep dives, they ride in small submarines
F. Life is more diverse than people previously thought
G. With sensors, some fish have traveled over 75,000 kilometers
