<human>: How does the octopus sense and feel with its tentacles?
<bot>: The octopus has a very sophisticated nervous system that allows it to sense and feel with its tentacles. It has specialized cells called tactile cells that are found in each of its eight arms, which allow it to detect vibrations and pressure changes. These tactile cells also provide the octopus with the ability to discriminate between different textures. Additionally, the octopus has specialized receptors on its skin that can detect light, chemicals, and even electrical fields.
