Which animal does not have a brain?

Question

Starfish

Answer 1

Jellyfish, coral, fungi, bacteria and famously slime moulds get by perfectly well without a brain.

Answer 2

Starfish do not have a centralized brain like most other animals. Instead, they have a nerve net that runs throughout their body, helping them coordinate movement and respond to stimuli.

Answer 3

While starfish do not have a brain in the traditional sense, they do have a complex nervous system that allows them to respond to their environment and exhibit behaviors such as feeding and moving. Instead of a centralized brain, starfish have a decentralized network of nerves called a nerve net.
