In doing so, we not only looked at the present time but also took a look back into the history of our blue planet.

What is the longest animal in the world today?

According to current research, the bootlace worm Lineus longissimus is the longest animal in the world. The species can reach a length of 180 feet (55 meters) but has a diameter of only 0.20 to 0.39 inches (five to ten millimeters). This is shown by a specimen washed ashore in Scotland in 1864. They live in the northeast Atlantic around the British Isles and along the Norwegian coast into the North and Baltic Seas.
