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 giant

deep-dwelling lifestyle is largely unknown but specimens have been found
globally, with the exception of Arctic and
Antarctic waters.
