he was fascinated to the octopus that are capable of changing color.
The color-changing cells in an octopus are called chromatophores. These specialized cells contain pigments and can expand or contract to change the color and pattern of the octopus's skin. In addition to chromatophores, octopuses also have other types of cells, such as iridophores and leucophores, which contribute to their ability to reflect light and create complex color displays for communication and camouflage. This remarkable ability allows octopuses to blend into their surroundings or signal to other marine creatures.
