Inter-special social interaction between intelligent Mollusks ( octopus, cuttlefish) is mainly visual. Thus they need complex eyes to communicate.
No, cockles do not have eyes. They are bivalve mollusks with a simple anatomy, lacking complex sensory organs like eyes. They primarily rely on their other senses to navigate and survive in their marine environment.
Yes, some mollusks do have eyes... right on the top. Also, octopuses, squids, and cuttlefishes are mollusks, and have beautifully evolved eyes.
It is the most complex type of mollusks.
Yes. They have extensive cephalization. They have a brain and eyes.
Cnidarians include jellyfish and corals. Cnidarians are less complex than annelids or mollusks because the latter have gills with many layers of tissue.
Simple and Complex eyes
They are mollusks (like clams). They do not have eyes, that I can tell. For some reason I cannot add related links. Wikipedia has a nice article on scallops.
If the insect in question has both complex eyes and simple eyes. the simple eyes are for close range vision while the complex eyes are primarily for longer range vision. If the insect has no complex eyes, then their simple eyes are used best they can for all around vision.
They all have complex ganglia to control breathing, movement, and digestion.
No, squids have complex camera eyes.
No, camera eyes like all other vertebrates. Mollusks also have camera eyes. Only anthropods and insects have compound eyes.
Mollusks exhibit greater complexity than roundworms in several key aspects, including their body structure and organ systems. Mollusks possess a more advanced and diverse body plan featuring a coelom, a muscular foot, and a mantle that can produce shells, whereas roundworms have a simpler pseudocoelomate structure. Additionally, mollusks often have specialized organ systems, such as a complex circulatory system and a nervous system with more developed sensory organs, enabling them to interact more effectively with their environment. This complexity allows mollusks to occupy a wider range of ecological niches compared to roundworms.
