Is there any animal that can live without oxygen?

Question

life & universe

Answer 1

Yes anaerobic bacteria.

Answer 2

there are many non-plant living things that do not rely on oxygen for survival.  Not really animals, though.  Unicellular organisms (bacteria etc.); living things not in the kingdom animalia.

Answer 3

there is no ANIMAL that can LIVE without oxygen because it is vital for their very survival. however there are some unicellular PLANTS like anaerobic bacteria, n fungi. respiration (taking in of O)  is needed for organisms  to degrade organic substances to release energy. but these anaerobic bacteria depend on some other non-oxygenic source like nitrates , ammonia for their energy supply. so no need for 0.      

eg:iron bacteria , yeast

  

    

Answer 4

may be sulphur bacteria if u count them as animals!!!

Answer 5

Some animals can live without oxygen for short periods of time including the various mud shrimps which live in burrows in muddy, peaty marine marshlands. When sufficient oxygen isn't available for respiration they can switch to anaerobic respiration.

There are probably others but i'm not familiar with them.

Answer 6

All anerobic bacteria can live without oxygen. infact oxygen is lethal to them.

Answer 7

no living thing can live without oxygen

Answer 8

There are very few animals that can.  Lots of bacteria in the ocean can (they live off sulphur in hydrothermal vents).

There are some simple animals like the tube worm that lives in the ocean that form symbiotic realtions with these bacteria and dont require oxygen.

Search in wikipedia for tube worms/hydothermal vents and follow the links there for more info about this.

As as far as I am aware no complex animal can live without oxygen.

Answer 9

YES THERE IS AN ANIMAL CAN LIVE WITHOUT OXYGEN.....THE UK-UK HERE IN THE PHILIPPINES

Answer 10

animals are living organisms and all living organisms respire so they need oxygen for basic body activities
