Transcript of UNDER THE SEA

Thousands and thousands of plants and animals live in seas all over the world. The water is home to ferocious sharks, gentle rays, huge whales and tiny fish. It is not known how many species there are as many parts of the sea have never been visited by man. Creatures of the Deep OCEANS UNDER THE SEA Jessica McLaughlin & Rachel Williams Interactive Learning Program for Grade 3/4 Students SHARKS Sharks are the best hunters in the sea. They have sharp teeth and huge jaws so they can easily tear up most things including seals and turtles. There are many different types of sharks including hammerhead, blue, tiger and great white (in the picture). Great white sharks can grow very big, in fact, up to 8 metres long. OCTOPUSES Octopuses have eight arms and soft bodies so that they can squash themselves into small cracks or holes to hide from predators. When they hunt for food they pounce on fish, starfish and crabs. Some also make webs to help net their prey. On their arms are super strong suckers so that they can hang on to rocks, grab food and pull themselves along the seabed. FISH Fish are quite amazing animals as they can get oxygen out of the water using their gills. Fish have lots of bones and many have scales that cover their bodies. There are three types of fish: bony fish, cartilaginous fish and jawless fish. DOLPHINS Dolphins are known to be similar to humans as they are quite intelligent and usually keep their babies for many years. Dolphins do not need to drink as they get their water from the fish and squid that they eat. Killer whales are actually fierce dolphins. They are the biggest type of dolphin. OCEAN ZONES OCEAN LIFE CYCLE TURTLES AND THEIR YOUNG- Reproduction HEALTHY SEAS It is important that we keep our seas healthy so that they are sustainable. This means that the world will be able to continue to support itself. There are small things that humans can do to help keep our seas healthy. This includes not over fishing, reducing pollution, preventing sea dumping and also reducing plastic pollution. We can do this by....
Cutting down the use of chemicals
Buying organic produce
Walk, cycle or use public transport
Turn down the heater
Re-use and recycle
Don't litter
Don't touch animals or reefs Plastic Pollution Almost three quarters of the world is covered by oceans and seas! Go onto this website to learn more about sharks and do a worksheet! Interesting fact: Shark skins
feel rough like sandpaper! Interesting fact: Octopuses are related to snails! Interesting fact: Fish don't need eyelids as the water keeps their eyes wet and free of dirt. Interesting fact: Bottle-nose dolphins (in picture) have over 100 pointed teeth. Every year, one million seabirds and 100,000 marine animals are killed by plastic litter. Plastic at sea can take between 450 and 1000 years to breakdown. Jess and a bottle-nose dolphin This is what can happen! The ocean is divided up into zones and as you can see in the picture, each zone has a different depth, water temperature, amount of light, and oxygen levels, and has particular groups of plants and animals. 0M 90M 180M 4000M 6000M SHORELINE SURFACE
ZONES THE ABYSS A special group of sea creatures live where the land meets the sea and they must adapt to the changing water levels which is called the tide. Many animals in the ocean depend on this particular zone as it is a main source of food for many sea creatures. This shallow forest sea bed is home to fish,
rays, octopuses, squids and crabs, and receives
warmth and light from the sun in some places although it is 180 meters deep! The ocean floor is made up of
mountains, deep holes and
active volcanoes, and
supports life in complete darkness. The creatures that live in this zone must be able to handle the increased pressure that comes with great depth. ZOOPLANKTON SCHOOLING FISH SEA BIRDS LARGE FISH/MAMMALS TOP PREDATORS All sea creatures depend on one another for food. This can be demonstrated by the following food chain: http://www.enchantedlearning.com/subjects/sharks/species/Greatwhite.shtml Please PAUSE music in the bottom left corner. Please PAUSE music in the bottom left corner. Now that you have seen some marine animals...
Draw your FAVOURITE underwater animal. Have you noticed any of these behaviours in your household?
