Cave salamander which can hold still about seven years, they live up to 100 years.

Just think about getting paused during playtime. Can you hold still for more than a minute? No, right?
Nature is a great creator to astound us completely. Creatures in the world are created according to their habitats. Here we are talking about the great amphibian Olms/Proteus salamander which can stay as it is for about seven years or around 2569 days.

Scientists from the United Kingdom and Hungary researched Olms that primarily live underwater caves in Bosnia-Herzegovina. An adult Olm salamander weighs 17grms and its scientific name is Proteus Anguinus. They are blind and do live, sleep, eat and mate under the water unlike most of the amphibians. They don't move for seven years that means they stay in one position, even they don't move to prey or eat. Since they do hold still for so long, there are no natural predators for the species. This is the main reason for having a long life span.

Since they are blind they do prey with their acute hearing abilities. When they eat, they eat small creatures like small shrimps and snails. They can slow their metabolism so they can live on a one-time meal for such a long time for nearly a decade.

Teams of researchers say these creatures hardly move around even when they are up. Maximum up to 32 feet one salamander moves that to one time preying and one-time mating. Typically, once in 12.5 years, they wake up and move to mate. Because of their low rate of reproduction due to their sedentary nature, they are so vulnerable and rare species.

The team of Divers has researched and collected data for eight years under the water in the complete darkness. They collected data by holding them, marking on them and putting them back of the same spot they were before.
They say creatures don't even move a bit even though they are caught. They don't do much but they are great predators in the cave ecosystem.
