underwater they need water to survive.
They survive because they live off of dead and alive animals that live in the ocean.
Snails cannot breathe underwater. They need air to survive as they have lungs or gills to take in oxygen from the air.
Monkeys cannot survive underwater, they'd need gills like fish. Since they have lungs they could only survive underwater for a short period of time.
Yes, white sharks have gills that allow them to extract oxygen from water, which is how they breathe underwater. They need to constantly swim to ensure a flow of water over their gills for oxygen exchange.
it depends. however most plants will need at least some light to survive
Shark finning. ALL sharks are seeing a decline in numbers as shark finning is threatening their chance of survival.
The ability not to drown, or a scuba diving kit.
If a baby is born underwater using the birthing method known as "Water birth" (a method of giving birth, which involves immersion in warm water.) it can survive underwater momentarily until you take it out of the water and takes its first breath. This is not to say that a baby born in water becomes capable of extended survival underwater like mythical mermaid.
Yes, plants underwater do need sunlight to survive. Sunlight is essential for photosynthesis, the process by which plants make their own food. Without sunlight, underwater plants would not be able to produce the energy they need to grow and carry out other essential functions.
This is actually not true at all times or for all sharks. It is true that most sharks need moving water in order to breathe, but there are underwater currents where sharks can stop, because the water is moving around them.
No, sharks need their dorsal fins to keep them upright and traveling straight.
