The giant squid is one of the biggest animals in the oceans. A typical adult is 35 or 40 feet long, and some are even bigger. Yet it’s almost never seen. Much of what we know about the creature comes from dead ones that washed up on shore. Only a few have been photographed alive and well in the oceans.

In 2018, though, a research team easily detected the giant squid’s presence in the Sea of Japan -- through molecules of its DNA in the water. The technique could help scientists keep tabs on the squid population throughout the world.

Whether it’s a swagger or waddle, a strut or a prance, the way a person walks can reveal a lot about their personality before they say a word. It turns out, the same may be true for fish. We don’t exactly have words, yet, for what a swordfish’s swagger or a sturgeon’s strut might look like, but scientists may soon. A group of researchers recently documented the fin movements of three-spined sticklebacks and found them to be distinctive enough to identify each fish by how it swam.
