It matters what temperature the water is at. If it is at normal, 20 degrees Celsius water, it will breath about 66 times per minute.
A Flying fish beats its tail between 50 and 60 times a minute
Fish do not have a pulse rate in the same way that mammals do. Instead, their hearts beat at a steady rate that varies by species. Generally, a fish's heart rate is much slower than that of a mammal.
i think its the heart beat
70 - 120 times
i think about 12 times
How many times a fish moves its gills in 1 minute depends on the species of fish and its size. Some species move their gills between 125 and 135 times a minute. Smaller fish move their gills more often than larger ones.
On a school trip, we did an assignment on this. A clown fish, while stationary opens and closes its mouth 42 times in one minute, while the fish that swam, although not in view was averaged at about 63.
Yea, they do. Almost every fish over 2 feet long will eat other fish in a heart beat
Different kinds of fish vary in their oxygen demands. In respiration, a human, in good health, takes about 20 to 25 times a minute, while some fish contrast between 12 to 150 breaths per minute. If the fish is exerting itself, or if the oxygen is low in the water, the inhaling goes faster (like a runner after finishing the mile).
it is sort of different for all fishes .for example a sperm whale breaths 3-4 times per minute
once!
