A squid gives birth to fully transparent pups

A team of scientists has managed the first gene inactivated in a species of cephalopod using the Doryteuthis pealeii squid, a common animal in the world of scientific research. They managed to eliminate a pigmentation gene in squid embryos, producing transparent offspring, as we can see in the image.

The achievement took place at the Marine Biology Laboratory (MBL), an affiliate of the University of Chicago, led by Joshua Rosenthal and Whitman Karen Crawford. By editing the CRISPR-Cas9 genome, they managed to eliminate a pigmentation gene, excluding the color of the eye and skin cells of squid, called chromatophores.
