Devil worm is a new nematode species. They were found in a gold mine at depths of 2.2 miles. Scientists previously believed that only microbes lived in those depths. The Isotope dating of the water hosting these microorganisms revealed that the nematodes were 3000 to 12,000 years old.

The deep-living organism can withstand high heat and extreme pressures. (source)

Sea anemones are water animals. They look like anemone flowers hence the name sea anemone. Sea anemones are related to corals, Jellyfish, and hydra.

The sea anemone does not have a mouth or anus. Instead, a gastrovascular cavity serves as the stomach with an opening to the outside. This opening acts as a mouth and anus. (source)

4 Birds and mammals avoid pylons or high-voltage power lines because they are terrified of ultraviolet flashes. These flashes are invisible to human eyes.

Scientists have found that mammals and birds avoid the pylons because they see them as a row of flashing lights. The regular flash of lights is not visible to human eyes. But the animals are able to see the ultraviolet and are terrified by it. (source)

The Blue whales communicate regularly by sound. Sound travels better in water than in air. Divers have reported that the vocalization of blue whales can be ‘felt’ more than heard. They make a deep, low-pitched sound that can be heard at a distance of over 500 miles. The low-pitched rumbling has been recorded as high as 188 decibels at one mile away from the source of the sound. (source)

6 Kiwis are the smallest ratite. However, female Kiwis lay the largest egg in relation to their body size of any bird in the world.

Kiwis are the smallest living ratites. DNA comparisons show that the Kiwis are closely related to the now-extinct Malagasy Elephant birds. Kiwis are the only bird to have nostrils at the end of their long beak.

They also have the largest egg-to-body ratio. The egg averages 15% of the female’s body weight in comparison to the ostrich, which averages 2%. (source)
