Pyjama squid (Sepioloidea lineolata) - BIODIVERSITY

As it matures, this chromatophore-clad pyjama squid (Sepioloidea lineolata) hatchling will learn to use the color-changing cells that adorn its body to alter its appearance.

The patterns on pyjama squid (Sepioloidea lineolata) are made up of chromatophores—pigmented cells that can expose or hide their color as they expand and retract, respectively.

According to graduate student Brittany Grouge of George Mason University, S.lineolata hatchlings develop color-changing abilities as they grow.
