i think its the heart beat
Amphibians have three-chambered heart and lungs for respiration, while fishes have two-chambered heart and gills for respiration.
Amphibians can live in water or land environments, as long as the land environment is moist enough for them, while fish can only live in the water. Their gills are specifically designed to filter oxygen from the water.
There are various uses of fish oil. Yes..Fish oil helps prevent heart attack. You can get more information from the related link
To monitor the rate of cellular respiration in fish, you can measure the levels of carbon dioxide (CO2) produced. As fish metabolize oxygen to produce energy, CO2 is generated as a byproduct. By measuring the concentration of CO2 in their environment or in water samples, you can infer the rate of cellular respiration occurring in the fish. Additionally, measuring oxygen consumption can also provide insights into their respiratory rates.
It will increase their blood pressure, heart rate & respiration which can make them susceptible to parasites or other illnesses
It is hypothesized that fish have higher respiration rates in warmer water because metabolic rates are faster in a warmer climate for exotherms. Results show that the respiration rate of fish was greater in the 76 degree Fahrenheit tank (mean=203 breaths per minute) than in the 71 degree Fahrenheit tank (mean=79 breaths per minute) (p=0.04). Another trend observed is that , although not significant, was that smaller fish have a higher respiration rate than larger fish in both temperatures (p=0.19).
frogs have many things such as bilateral symmetry a mouth and an anus they are cold blooded creatures fish are vertebrates. Their (bone) skeletons give their bodies structure.
The zebra fish will have a higher respiration rate
Fish do not have the same type of heart attack as humans because their cardiovascular systems differ. However, fish can experience a heart-related issue called barotrauma, where sudden changes in pressure can damage their organs, including the heart.
Although I can not say authoritatively, I can however say that fish can not "hear" as we do but instead sense vibrations with their swim bladder. Some fish, particularly fresh water Amazonian fish, sense the vibrations from thunder storms which act as a signal to spawn. Bass frequencies in music can imitate this. One would assume that their respiration rate would increase as a result of the urge to spawn.
All fish respire via the gills.
Animals = lungs Fish = gills
