Watch a baby nursehound grow, week by week, in this video

This extraordinary video was produced ages ago – in 1977, and you can tell by the funny hair style! – by a group of Sicilian divers who collected two nursehund eggs off Palermo and filmed the development of the baby sharks.
Watch as they film and sketch on paper, week after week, the growth of the two little sharks!
It was a pioneer video which received then the prestigious "Sesto Continente Award".
With deep gratitude to the cameraman, Alberto Romeo, who uploaded it on youtube expressily for us!
