Beautiful, isn’t it? 😉
This is called “The Butterfly of the Sea“, also Sea Robin, or Gurnard.
This interesting fish is a bottom dweller, that means it avoids going to the upper parts of the underwater – they can even “walk” underwater by making movements with their pelvic fins and other parts of their body. It’s not related to flying fish, nor do they glide in air, the large pectoral fins are normally held against the body but are spread out when threatened to put off predators
