Adult sponges are immobile, but can respond to specific physical stimuli despite the lack of traditional organs and sensory systems. Since the sponge has no nerves or brain, it does not have the ability to cognitively control movement.
Do the sponges have nerves or muscles?
Sponges are the simplest animals, and unlike most other animals, they have no nerves or muscles. They sit stationary on rocks and are insensitive and incapable of reacting to changes in the surrounding environment.
Does the sponge have nervous tissue?
Sponges are the only multicellular animals without a nervous system. There are no nerve cells or sensory cells. However, touching or applying pressure to the outside of the sponge causes the body to contract locally.
Can sponges feel pain?
Sponge communication systems are less well known because they lack a fully developed nervous system. That is also the reason why sponges cannot feel pain.
Does the sponge lack the nervous system?
