  1. 1. LIFE IN WATER
  2. 2. Ocean is home to over 30,000 species of fish, but unfortunately over 1000 species are facing extinction. Their habitat can be a puddle, a pond, a river, a sea, an ocean, a wetland or a volcanic lake. The balance of the life in water is getting lower and lower because humans are destroying the habitat of millions of fish, and because of that the climate changes constantly which causes death of many fish.
  3. 3. This are some habitats of fish: • Wetlands: Brown trout fish, rainbow trout fish and redfin perch fish. • Seagrasses: sharks, turtles, marine mammals (dugongs and manatees), mollusks (octopus, squid, cuttlefish, snails, bivalves), sponges, crustaceans (shrimp, crabs, copepods, isopods and amphipods) polychaete worms, sea urchins and sea anemones. • Deep ocean: lantern fish (the most common deep-sea fish), flashlight fish, cookie cutter shark, bristle mouths, anglerfish, viperfish, some kind of eelpouts and bioluminescent fish ( you will see later on what this type of fish is)
  4. 4. Wetlands Seagrasses
  5. 5. DEEP OCEAN
  6. 6. Fish that live in coral reefs are turtles, sharks, eels, crabs, shrimps, urchins, sponges and other small organisms. Corals are a kind of plant in the water, they look like plants and shells, however, unlike rocks, corals are alive. And unlike plants, corals do not make their own food. Corals are actually made up of thousands of tiny animals called polyps. A coral polyp is an invertebrate, which means that it doesn’t have a spine, that can be no bigger than a pin. Coral reefs are some of the most beautiful places on Earth to visit. You can find coral reefs in tropical oceans near the equator, like Central America. You can also find coral reefs in Hawaii and the Red sea.
  7. 7. • Whale Shark: The biggest, most horrifying, that killed many lives… the Whale Shark. It feeds on plankton, krill, fish eggs and small squid or fish. An adult ways about 19,000kg. The largest whale shark ever lived was over 14m long and weighed 21.5 tons. Whale sharks live for about 100-150 years. • Great White Shark: The second biggest shark in the world. It is also known as white pointer, white shark or white death. Its scientific name is Carcharodon carcharias. An adult weighs about 680-1,100kg. Females can grow up to 4.5-6.4m long, but males can grow only up to 3.5-4m long.
  8. 8. • Blue Whale: The blue whale is the biggest whale on this planet and may be the biggest creature on Earth. It can reach up to 30m long and it can probably reach over 181 tons. Its scientific name is Balaenoptera musculus. Its lifespan is 80-110 years. • Finback Whale: This whale is the second biggest whale on Earth. These mammals can reach 95 feet long and weigh up to 78 tons. Scientists also call this great mammal the greyhound of the sea.

  11. 11. • So, what are bioluminescent fish? These are the most awesome fish on Earth. Their body produces light. But how does this happen? This light comes from their skin. A chemical reaction happens on their skin and light is produced. This is helpful for these fish because they live in the deep sea which there is no light there, but they can use their skin to light up the place. They can use their light whenever they want. There are also bioluminescent corals which are similar to bioluminescent fish. A chemical reaction happens and light is produced.

  13. 13. • Of all this underwater discoveries, thonis is the most fascinating. Thonis was called Heracleion by the Greeks and Thonis by the Egyptians. Thonis was an ancient Egyptian city located near the Canopic Mouth of Nile. It’s 2.5km off the coast, under 10m of water. It’s legendary begins as early as the 12th century BC, but was only discovered in 2000 by the French underwater archeologist Franck Goddio. This city was lost because of natural disasters close to the 8th century A.D and was forgotten for about 12,500-13,000 years until Franck Goddio found it again in 2000.
