MANTENANCE OF THE AQUARIUM

MANTAINANCE OF THE AQUARIUM

One of the best important thing once the aquarium is created is the manteinance of it in order to create a propper environment to fish. 

We have to follow some tips:

• FEED FISH

SIXTH DAY: MARINE ANIMALS IN DANGER

Marine animals in danger of extinction!

Do you know how many marine species are in danger of extinction?

More or less there is estimated that over 2.150 marine creatures are in danger og being extincted.

 This is a awful problem which is living the aquatic life and it needs a rapid solution. Otherwise, these marine animals would cease to extsit,

Which are the reasons of being too many endangered sea animals?

• Loss of marine habitats 

• The spread of disease

• Pollution

• Too much fishing practice

Some fish which are in danger of of extinction:

European Eel

 

Goliath Grouper fish

Bocaccio rockfish

Winter Skate

FIFTH DAY: MARINE LIFE (ll)

   FUNGI

They are species which live in marine or estuarine environments. Over 1500 species of fungi are known more or less. They parasite marine algae or animals or are saprobes on algae, sea wood, sea grasses and can be found in sea foam. There can be appreciated some examples of fungi above:




PLANTS AND ALGAE
There is a great variety of plants under the sea and ocean. Marine plants and algae are known as seaweed. . Aquatic plants and algae provides an important habitat for life under the water. These seaweeds creates underwater kelp forests: Look at the pictures to know different kinds of algae and aquatic plants as well as kelp forests:

TWO KINDS OF FISH WHICH CAN BE INTRODUCED IN AN AQUARIUM

 FRESH WATER FISH  

Freshwater fish are fish that spend some or all their lives in fresh water. The salinity of water what they live is under 0,05 %

 For instance the places which they live are:

River

Lake

Freshwater fish survive thanks to physiological adaptations. It is important to mention that 41,24 % of fish are found in fresh water.

There can be seen different kinds of freshwater fish above:

AFRICAN JEWELFISH

 BLACK TETRA

LIVINGSTON´S CICHILID                     

                                                                                                                       

SALTWATER FISH

Saltwater fish are fish that spend some or all of their lives in salt water. This water is composed with a salinity of more than 0,05%.

The places which live saltwater fish are the following ones: Oceans 
                                                                                     Salt rivers

Some examples of saltwater fish:

CLOWNFISH

                                                                                                ANTHIAS FISH

THIRD DAY: MARINE LIFE

 MARINE LIFE

In the marine environment that we have just seen supplies different kinds of habitats that supplies marine life. Marine habitats can be divided in coastal habitats and open ocean habitats:

Coastal habitats

Open ocean habitats

The marine life refers living beings or organisms which live in water zones There can be found the following ones:

ANIMALS

Invertebrates

Marine invertebrates are animales which live in the sea. As we have learnt invertebrates are animales without any bones. They are multicelular and they habit in marine environment. Some invertebrates could have on their own a shell or a hard exoskeleton. There are different kinds of marine invertebrates. There can be appreciated some species of marine invertebrates above:

Jellyfish

Flamingo tongue snail

Annelida

Crustacea

VERTEBRATES
Birds
There are some birds which live in the marine environment. These birds are referred as seabirds. Most of them live in the ocean, but there can be found some species of seabirds in land. Albatross, penguins, gannets and auks are some examples of marine birds or seabirds.  

Penguins

Albatross

Gannets

Auks

Mammals

Marine mammals are marine species which live in the aquatic environment.   There are 129 species of marine mammals. There can be differenced the following marine mammals:

Whales (in the picture  orca
or
the kller whale)

Seals

Dolphins

Walruses

Sirenians

Reptiles

Marine reptiles are animals which inhabit in aquatic zones because they have adapted to for an aquatic environment.  Some of them put their eggs in in land and need to return to land for them. Therefore, we can say that reptiles´ reproductive method is oviparous. Here are some examples of marine reptiles.

Sea turtles

Sea snakes

Terrapins

Marine Iguanas

Saltwater crocodile
