There are possibly sharks in the ocean of Vietnam, but do not get panicked. The South China Sea (or East Vietnam Sea) flowing around Vietnam is known for its huge number of inhabitants, and the water temperature is not lower than 20 degree Celcius. Sharks do not like shallow beaches with crowds of noisy tourists. So the risk of meeting a shark in this sea area is not likely. To see such deep-sea habitats, you need to go diving deeply using diving gears.
