Scientists at United States National Oceanic and Atmospheric Administration or NOAA, have discovered very rare fully warm-blooded fish named Opah. It is a discovery that defies conventional biology.
- Opah fish are reddish in colour with white spots and has distinct red fins.
- It has an oval shaped body and weighs upto 90kgs.
- It is normally found in deep waters at a depth of 50 to 400m.
- It mostly preys on the fishes and squids.
- The uniqueness of these Opah fishes is they can produce electricity by their pectoral fins flapping continously.
- The heat generated does not get lost to the environment because of its unique shapes.
- The heat produced have average muscle temperature of 4 to 5 degree above surrounding water temperature.
- Main advantages of being warm blooded fish are faster swimming speeds, better brain and eyes functions, withstand the effects of cold on vital organs when compared to cold-blooded fishes.
- NOAA wants to compare Opah from different parts of the world to see how they have evolved warming mechanisms in deep waters
NOAA- some details
- NOAA is an American scientific agency.
- It aims on conditions of oceans and the atmosphere.
- It was formed on 10th of February 1910.
- Head quarters is in Maryland USA.
- Agency Executive is Kathryn D Sullivan.
Warm and Cold blooded animals- some facts
- Warm blooded animals produce their own heat and can maintain body temperature independent of the environment.
- They are also referred as Endotherms.
- Birds and mammals are mostly warmblooded in nature.
- In case of cold blooded animals, their body temperature depends on the temperature of the surroundings.
- Cold blooded animals are also called as Ectotherms.
- Most of amphibians,reptiles and most fishes belong to cold blooded category.
