Yolk Matter and Sperm Cells – A Common Factor in the Production of Blue Whales
Blue whales reproduction process is a little known fact. It is believed that these animals give birth to live babies only once each year. In fact, they give birth to one or two babies at a time. This makes it a rare event for a mother to have more than one pup. It is estimated that it takes these animals about a month to give birth.
A blue whale’s blowhole (also the equivalent of nostrils) tends to be about 20 feet in circumference. The actual size will vary depending on the species. Regardless, a blowhole this large is probably more than enough for the blue whales to breathe. The huge lungs of these massive animals are used for everything from ocean air to food. With this large lungs, blue whales use their blowholes to breathe and also to hunt.
An average blue whale has a lifespan of around twenty years. The older a whale is when it becomes a father is when he is considered old. He is also the largest animal that is alive and the second oldest. While not as fast as some other animals such as dogs or cats, these animals move with a great deal of speed and can cover long distances very quickly. Because of this, they are wonderful hunters and have been compared to “sea creatures” such as whales and dolphins.
These animals are thought to be the most dominant blue whale population in the world. On rare occasions, you will see a black or gray colored whale along with the blue whales. However, they will usually only come together to hunt or travel in large groups. These groups can be quite large. There are reports from sailors who have seen these large groups of blue whales at times but there has never been any recorded sighting of a blue whale swimming together with whales of other colors.
If you were to go on a treasure hunt off the west coast of Mexico and South America you would find the remains of what was the megalodon. This creature would have been over 100 feet in length and weighed nearly twice as much as a blue whale. It had a very massive head with a very large mouth. Megalodon lived during the Cretaceous geological period and grew to an amazing size. Some scientists believe that the megalodon might have been the largest animal to ever live on earth.
There are a lot of factors that can effect the rate of reproduction of blue whales. They are able to breed even though they are much larger than the typical sperm whale. Some scientists estimate that the reproductive capability of these creatures could reach up to ten tons per day.
