In a YouTube video, posted last week, a man managed to resurrect a frozen fish back to life. The video that shows a man dropping a seemingly dead fish, covered in ice, in a tub has the Internet baffled.

A lifeless fish is seen submerged in the water. However, in a short time, its fin starts moving, its eyes open and bubbles were coming from its mouth.

Next, the fish starts moving its tail and starts swimming around the container. By the onlookers’ astonishment, the fish presumes that coming back from the dead is not entirely far-fetched at all.

It’s unclear when or where the video was taken. Moreover, no experts have discussed the authenticity of the footage yet. For now, viewers are left to decide whether to declare this as an ingenious hoax or a genuine one.

However, this is not the first time a frozen animal have been brought back to life. In December 2015, a US family from Utah resurrected a kitten back to life after performing CPR in front of their fireplace.

The cat, now named Lazarus, was found buried under snow on Thanksgiving morning. In another YouTube video, Lazarus is seen to be healthy and pampered.

Moreover, Japanese researchers have revived a tardigrade, an eight-legged, microscopic creature commonly known as water bear, earlier this month. The water bear has been frozen for more than 30 years but it has managed to not only survive that long, but it also laid 19 eggs, 14 of which have already hatched.

Interestingly, researchers have been discovering animals that have been previously thought to be extinct.  Recently, a team of Spanish, German and Portuguese scientists discovered five “extinct” species of bird species in Madeira and the Azores.

Scientists strive to resurrect more extinct animals. With the advent of innovative technology, doing so successfully may happen very soon.
