A "gurnard" is a common name for fish belonging to the family Triglidae, also known as sea robins. They are characterized by their bony heads and the presence of specialized fin rays that they use to "walk" along the seabed. Gurnards also produce distinctive sounds using their swim bladders. They're like the 'weirdos' of the sea, because most fish don't walk or make noise. Gurnards are found in various marine environments and are often colorful and interesting to observe.
