We wanted to make a useful infographic that can be a quick and enjoyable reference to remember or study 13 different animal heart rates and fun facts!
After reading this article, you can look forward to holding your own when chatting about the heart rates of these animals.
Animal Heart Rates
In our community, we have veterinary professionals that work not only in a small animal practice, but also with large, exotic, and wild animals. Animals that are smaller in stature usually have faster pulse rates. This due to the fact that it takes more force to push a certain amount of blood through tiny blood vessels than through larger ones, so the heart has to pump more to push it through.
Some animals have got more than one heart. The Hagfish has a total of seven hearts! Octopi have two “gill hearts”, and Earthworms have five hearts, that are called arches in their segmented bodies.
An interesting analysis conducted by San Jose University is to consider the effect of scale changes for creatures that are similar in shape and only differ in scale. As the scale of an animal elevates the body weight, the volume increases with the cube of scale.
The volume of blood flow required to feed that bulk also goes up with the cube of scale. The cross-sectional area of the arteries and the veins required to carry that blood flow only increases with the square of scale.
Here are 13 animals heart rate statistics and other cool facts!
