Interesting Facts about Dolphins
With so much to know about dolphins, it is often the fun facts that people really enjoy and they are really good for school projects. Do you want to know how dolphins sleep? The fact is dolphins cannot actually sleep because they need to be conscious to breathe. Instead of going into a deep sleep where they would suffocate themselves, they often left half of their brain sleep at one time and then the other half at another time. In this way, dolphins are able to "sleep" about eight hours per day.
Here are more interesting facts about dolphins.
Dolphins as we know are predators when it
comes to fish and other foods. But how much do they really eat per day?
That really depends on the season and how much food is available in the
area in which they live. If they are in an area where fish with high fat
content are readily available then they may eat less of mackerel and herring
then if they were to just eat squid. So to get the same calorie intake
they need to eat more squid. On average they eat between 4% and 9% of
its body weight in fish so if they weigh about 250kg they will need to
eat about 10 to 22.5 kg per day of fish.
Another common question that people ask is
about how long dolphins live. The maximum age that dolphins live is between
40 and 50 years old which is much longer than people expect. Although
it is true that depending on where they live they may only live to about
25 to 30 years. There are some places such as the Indian Ocean where they
only live between 10 and 14 years on average. The warmer the water the
longer they will live.
Another interesting fact on dolphins is how deep they can dive. In an amazing study one bottlenose dolphin named Tuffy was shown to dive as far as 300 meters! Most of the dolphins do not dive this deeply though and live in fairly shallow water. In Florida for example, most dolphins live in water as shallow as 2 meters. There are some other dolphin species such as a pilot whale that can dive to at least 600 meters and a sperm whale that can dive as far as 900 meters, but most dolphins as we know them are not able to dive this deeply.
