Which animal has the most advanced nervous system?
humans
What has a well developed nervous system among all invertebrates?
The nervous systems of invertebrates are smaller and contain fewer neurons than those of vertebrates, yet they generate the great diversity and complexity of behaviour that has contributed to the incredible success of these animals.
Which group of invertebrates have well developed neuron organization?
Unlike the hydras and jellyfish, invertebrates such as sea stars (echinoderms) display some centralized organization of the nervous system. A ring of neurons is located in the center of the sea star, and simple bundles of neurons called radial nerves extend from the ring to the tip of each arm.
What is a Blue Hole in the Bahamas?

What do you call a giant octopus?

What is the longest squid in the world?
Giant squid live up to their name: the largest giant squid ever recorded by scientists was almost 43 feet (13 meters) long, and may have weighed nearly a ton. You’d think such a huge animal wouldn’t be hard to miss.
Why do squid have blue blood?
More primitive species (like the octopus, squid, and a number of other invertebrates) use a different protein, called hemocyanin, which relies on copper, rather than iron, as the binding mineral of choice. When copper binds with oxygen, the discoloration is different, resulting in the blue color of their blood.
