Giant squid genetics reveal family secrets


Giant squid around the world are “basically identical” despite looking very different, say scientists.

The super-sized cephalopods live deep in the oceans and are little-known by the scientific community.

An international team of researchers investigated rare samples of the elusive animals’ DNA to reveal their family secrets.

They discovered that there is just a single species of squid with no population structure.

The findings are published in the journal Proceedings of the Royal Society B.

    The evolutionary biologist commented that although the team had succeeded in answering one question about the mysterious squid, they have uncovered many more.

    That’s science!!
