In an innovative study of visual function in a variety of fish including sharks and drums, Horodysky’s lab used electroretinographic techniques to describe light sensitivities and the color wavelengths that these fish respond to. The five fish studied occupy turbid coastal and estuarine habitats throughout their range, and their visual systems are well adapted to prevailing light conditions. Environmental changes may alter the behavior of these fish.

You are assigned a task at work to create the perfect marketable fish bait. Draw (with color) and describe the most ideal bait for either a catfish or a tuna. Describe how this will move through the water when fished and other features that would make it more marketable to anglers. Modify your design and description after you complete your reading of this chapter. 3.3 How We Study Sensory Ecology This sensorial app has many unique features in comparison with other sensory based games, such as the firework, bubble, balloon pop and finger paint games available. Choose to amuse your baby with this visually stimulating, interactive, sensory game. Among teleosts, the electric catfish uses electroreception to navigate through muddy waters. These fish make use of spectral changes and amplitude modulation to determine factors such shape, size, distance, velocity, and conductivity. The abilities of the electric fish to communicate and identify sex, age, and hierarchy within the species are also made possible through electric fields. EF gradients as low as 5nV/cm can be found in some saltwater weakly electric fish. [27] Several basal bony fishes, including the paddlefish ( Polyodon spathula), possess electroreceptors. The paddlefish hunts plankton using thousands of tiny passive electroreceptors located on its extended snout, or rostrum. The paddlefish is able to detect electric fields that oscillate at 0.5–20Hz, and large groups of plankton generate this type of signal. [28] [29] Stewart, T. A., and M. E. Hale. 2013.

Daily cycles of light intensity are sensed by photoreceptors in the eye and pineal organ in the brain, which contains light-sensitive nerve endings. Vision is a dominant sense of fish that we humans can appreciate. Whether the fish finds a meal or becomes prey depends on many senses, such as the abilities to see, hear, smell, taste, and to detect water movement and electrical fields. Fish have a special sense that humans do not have: the ability to detect vibrations moving through water. Because sound vibrations move easily through water, fish do not need external ear openings, and yet they also have sensitive hearing.

Fish have excellent systems for hearing as well as a lateral line for detection of far-field water movements. Sensory game play is great for the continued development of your kids motor skills and hand eye coordination development. It aids in helping to fine tune the motoric skills and movements, the very detailed movements that we require and use every day.Konishi, J., and Y. Zotterman. 1961.

Sensory ecology focuses on the study of animal sensory systems to understand how environmental information is perceived, how this information is processed, and how this affects interactions between the animal and its environment (Dangles et al. 2009). The stimulus-response model (Figure 3.2) describes the basic reactions from the stimulus, through receptors to the central nervous system and brain, which are then transmitted to neurons and organs that respond due to detection of the stimulus. A stimulus is any change in the environment (either external or internal) that is detected by a receptor. It may be a predator threat, an easy prey item, or a potential mate. Receptors transform environmental stimuli into electrical nerve impulses. These impulses are then transmitted via neurons to the central nervous system and brain where decision making occurs. When a response is selected (consciously or unconsciously), the signal is transmitted via neurons to effectors. Effectors are organs (either muscles or glands) that produce a response to a stimulus. A response is a change in the organism resulting from the detection of a stimulus.

PMID 10580499. S2CID 4422490. The lateral line in fish and aquatic forms of amphibians is a detection system of water currents, consisting mostly of vortices. The lateral line is also sensitive to low-frequency vibrations. It is used primarily for navigation, hunting, and schooling. The mechanoreceptors are hair cells, the same mechanoreceptors for vestibular sense and hearing. Hair cells in fish are used to detect water movements around their bodies. These hair cells are embedded in a jelly-like protrusion called cupula. The hair cells therefore can not be seen and do not appear on the surface of skin. The receptors of the electrical sense are modified hair cells of the lateral line system. Fish can sense sound through their lateral lines and their otoliths (ears). Some fishes, such as some species of carp and herring, hear through their swim bladders, which function rather like a hearing aid. [9]
