The majority of our planet is covered in water. Water can be found in the north and south, and has helped to create a wide variety of different habitats. Animals in different habitats take different approaches to overcoming the obstacles they encounter there. In natural selection, the individuals that are best suited to the habitat are more likely to pass on their genes, and evolution takes place. This leads to an incredibly diverse variety of life, including some truly amazing animals. Our seas are full of incredible creatures, ranging from the very small to the largest the planet has ever seen. These creatures can be impressive, fearsome, and sometimes just downright unusual.
Many of these animals really help to capture our imagination and have been the subject of myths and fascination for as long as we can remember. Some present a risk to us, while many more are at risk because we pose a very real threat to them. The good news is that we are making efforts to protect the variety of life in our seas, and hopefully our efforts are not too late.
Here’s a look at 10 of the animals that have inspired in us the most fascination over the years, and that have been so essential to the oceans and the rest of our planet.
10. The Blue Whale
Living on our planet right now is the largest creature that has ever lived on Earth. It is a truly enormous animal, measuring over 100 feet in length when fully grown. While it is difficult to weigh the blue whale accurately, it is estimated that the largest specimens weigh in excess of 200 tons. Despite being so large, the blue whale feeds on krill, which is one of the ocean’s smallest inhabitants. Of course, in order to get enough nutrition, it needs to eat large numbers of krill. In fact, a single adult blue whale will eat around 4 tons of krill every single day.
Unfortunately for the blue whale, they have been mercilessly hunted to near extinction. International efforts, however, have helped to protect them, and their numbers have stabilized and are slowly rising. While they are not completely safe just yet, it looks as though these magnificent creatures will be living in our seas for many more years to come.
