Though giant squid are present around the world, they're likely to all be part of the same genetic family, according to a study published in the Proceedings of the Royal Society B. Researchers examined the mitochondrial DNA of 43 soft-tissue samples and found little differences between them. The findings are extremely surprising, said study researcher Tom Gilbert. The genetic diversity of giant squid is one of the lowest of any marine animal, suggesting that the animals are capable of breeding with any other of its kind no matter where they are in the world.
