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
ZONE TWILIGHT &
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.

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.
