Nociceptors are sensory neurons that enable nociception by detecting noxious stimuli where they are located in the body.18 Many anesthetics rely on blocking nociception to mitigate the noxious stimuli signals that reach the brain.19 Whereas pain is a conscious experience in the brain, nociception is the lower level detection of noxious stimuli, which can be translated into pain in an animal capable of experiencing it. This is how they get their name, since the word scallop means to leap or dance.. They lack what would be considered a central nervous system and brain.

However, it is concluded that fish lack these essential characteristics and therefore do not feel pain. Therefore, if an animal doesnt have the ability to move out of harms way, there might be no evolutionary reason for the ability to feel pain.13.

Mollusks are not sentient beings because they lack a brain and central nervous system. Scallops are often considered intelligent species because of their behavior. 24 Kamenos, N.

Sea scallops feed by filtering phytoplankton or other small organisms out of the water column, which can actually help to improve water quality by removing suspended materials.

Gastropods are able to sense light through their eyes, and some bivalves have simple eyes that are able to detect changing patterns of light and motion, but they lack well developed eyes like those of other mollusks such as octopuses and squids.16 Snails navigate primarily through their sense of touch and their sense of smell.17 Therefore the sensory abilities of bivalves and gastropods are probably not very complex. Clams, like all invertebrates, are not motile and do not have a brain. They maintain home territories and will return to the same place to sleep or hibernate.37 Though balancing needs and navigating do not necessarily indicate sentience, it might suggest they have an inner world that has some complexity and this could indicate an adaptive rationale for them to be sentient.
