EL SECRETO EVOLUTIVO DE LOS CALAMARES_ CÓMO CONQUISTARON EL OCÉANO

Squid are a group of marine mollusks belonging to the class Cephalopoda—the same class that includes octopuses, cuttlefish, and nautiluses.

They evolved into active, predatory animals, developing a hydrodynamic body, highly specialized eyes, a complex nervous system, and a remarkable capacity for jet propulsion.

In this documentary, we will uncover the secrets behind the extraordinary biology of these incredible creatures.

Today, squid inhabit virtually every ocean on the planet. Some species live among sun-drenched tropical reefs.

Others undertake vertical migrations of hundreds of meters every single day, while some dwell in the dark depths.

Few life forms have managed to conquer such diverse environments using the same set of fundamental biological tools.
