How does a amputated tail of lizards regrowth

The self-amputation lizards perform while being attacked by predators known as autotomy. Lizards take the term fight-or-flight to a whole new level. When pulled by predators, lizards shed their tails in response. This self-amputation is called autotomy.

The severed tail continues to wiggle for about 30 minutes. It follows an elaborate repetitive and diverse motion. Which includes flips up to 3 cm in height. This distracts the predator enabling the lizard to escape.

Immediately after tail loss, the tail stump ends in a terminal tail vertebra and involves a severed spinal cord. After 7-10 days, wound epidermis migrates over the tail stump and thickens to form an apical cap. Cells liberated from stump tissues collect under the apical cap and proliferate to form a blastema. The spinal cord regenerates and infiltrates the blastema. The regenerated lizard tail spinal cord is characterized by a prominent ependymal tube.

😳Why❓❓❓

Why we cannot see in the dark?

The optical nerve connected to the retina carries the image signal into the brain which resizes the image and helps us to view the object. During darkness, no reflected light will fall on the retina. Hence, no image will be formed by eye. That’s why we can not view any object.
