As a marine biologist with a keen interest in the study of invertebrates, I often find myself delving into the intricacies of sea star biology and behavior. Sea stars, also known as starfish, are fascinating creatures that have captivated the curiosity of scientists and the general public alike. One of the most intriguing aspects of sea star research is the question of whether they possess feelings or emotions, a topic that has been the subject of much debate and speculation.
To begin with, it's important to understand that sea stars are invertebrates, which means they lack a backbone and the complex central nervous system found in vertebrates. This fundamental difference in anatomy leads to a different set of sensory and cognitive capabilities. However, this does not mean that sea stars are devoid of any form of sensation or perception.
Sensation is the process by which organisms receive and respond to stimuli from their environment. In sea stars, sensation is primarily facilitated through their internal plexi, which is a network of fluid-filled canals that run throughout their body. These canals are connected to the outside environment and allow sea stars to sense changes in their surroundings, such as changes in water pressure and the presence of food.
In addition to their internal plexi, sea stars also possess a peripheral nervous system. This system is composed of a series of radial nerve cords that extend from the central disc of the sea star to the tips of its arms. Along these nerve cords, there are clusters of neurons known as ganglia, which help process sensory information. The peripheral nervous system in sea stars is not as centralized or complex as that found in vertebrates, but it plays a crucial role in their ability to sense and respond to their environment.
Sense organs are specialized structures that detect specific types of stimuli. While sea stars do not have the same range of sense organs as vertebrates, they do have receptors throughout their skin that can detect various environmental cues. These receptors are sensitive to changes in pressure, temperature, and can even respond to stimuli that might be perceived as pain in more complex organisms.
It is important to note that the concept of feelings or emotions is often associated with higher cognitive functions and self-awareness, which are typically found in organisms with more advanced nervous systems. Sea stars, with their relatively simple nervous systems, do not possess the capacity for complex emotions as we understand them. However, their ability to sense and respond to their environment suggests that they do have some form of subjective experience, albeit vastly different from our own.
The question of whether sea stars have feelings is complex and requires a nuanced understanding of the biological underpinnings of sensation and perception. While they may not experience emotions in the way that humans or even some other animals do, their sensory systems are sophisticated enough to allow them to interact with their environment in meaningful ways.
In conclusion, while sea stars do not have feelings in the traditional sense, they do possess a range of sensory capabilities that allow them to detect and respond to stimuli in their environment. Their internal plexi, peripheral nervous system, and sense organs work together to provide them with the ability to sense pressure, temperature, and potentially even pain. Understanding the sensory world of sea stars is an important step in appreciating the diversity of life on our planet and the myriad ways in which organisms perceive and interact with their surroundings.

Sensation. In addition to through their internal plexi, starfish feel through their peripheral nervous system, the sense organs. ... Starfish also have receptors throughout their skin that sense pressure, temperature and pain much as ours do.
