3. An aquatic animal is an animal, either
vertebrate or invertebrate, which lives in water
for most or all of its life. It may breathe air or
extract its oxygen from that dissolved in water
through specialized organs called gills, or direct
through its skin.
5. HABITAT OF FISH and how do they breathe ?
Fish live in the water.
Like all living thing fish need oxygen to live.
They get oxygen from water by taking water
into their mouths and passing it over their
gills.
6. 1 Marine Habitats
Marine habitats are the home to seaweeds,
or marine algae (brown, green, red), sea
grasses, which are the only marine flowering
plants, and mangroves, located on muddy
tropical shores.
7. FRESHWATER HABITIAT
Lakes and rivers are created by streams high in the
mountains that flow down when evaporated sea
water falls as rain. The majority of the water that
evaporates out of the ocean disappears into the
atmosphere but the rest falls as rain into the
freshwater rivers and then back into the sea. Streams,
rivers and lakes are home to countless animal species
all around the world.
8. Coasts are places where the land meets the sea.
Australia is an island and has a huge coastline
that has many different habitats. Coastal
habitats include beaches, rock pools, estuaries
and mangroves.
