Animals with nerve nets, such as jellyfish and sea anemones, do not exclusively have motor neurons. They possess a decentralized network of neurons that includes sensory neurons, which allow them to detect environmental stimuli, in addition to motor neurons that control movement. This simple neural architecture enables them to respond to their surroundings without a centralized brain.

What is primitive nerve nets?
A nerve net is a type of simple nervous system that is found in members of the cnidaria and echinodermata phyla . Nerve nets consist of interconnected neurons lacking a brain or any form of cephalization. This nervous system allows cnidarian to respond to physical contact. They may then detect food and other chemicals in a rudimentary way. Although the nerve net allows the animal to respond to its environment, it has trouble alerting the animal from where the is coming. For this reason, simple animals with nerve nets, such as haunda, will typically respond in the same way to contact with an object, regardless of where the contact occurs. Hydra, which are cnidarians, have a nerve net throughout their body. On the other hand, , which are echinoderms, have a nerve net in each arm, connected by a central radial nerve ring at the center. This is better suited to controlling more sex movements than a diffuse nerve net .
What are the simplest nervous systems called?
The simplest nervous systems are called nerve nets. They are found in organisms like jellyfish and sea anemones and consist of interconnected neurons spread throughout the organism's body without a centralized brain or ganglia.

How many animals die in sharknets?
Shark nets 53,098 marine animals are killed
Does a sea anemone have a nerve net?
Yes - all Cnidarians have nerve nets, simple nervous system where neural pathways are interconnected and is evenly distributed in the organism.
Do sharks mistake the nets for other animals or people?
yes
Why are drift nets illegal?
They are killing thousands of animals!
What is the main cause killing marine animals plastic bags or shark nets?
Both plastic bags and shark nets pose threats to marine animals, but shark nets are specifically designed to catch and kill sharks, while plastic bags often entangle marine animals causing injury or death. Therefore, the main cause killing marine animals would depend on the specific context and location.
