This Fish Has A Leg Up On The Competition | Defector
Briefly

The sea robin, initially appearing as a typical fish, develops unusual pectoral fins that resemble legs, allowing it to walk and search for prey on the seafloor.
Researchers discovered that sea robins utilize their leg-like fins not just for walking but also for tasting buried prey, broadening our understanding of their sensory capabilities.
The study of sea robins' genetic development and sensory biology presents compelling insights into the adaptive evolution of new organs, contributing to broader evolutionary biology.
The investigation into the morphological and molecular aspects of sea robins’ legs has significant implications for understanding not only this fish but developmental biology as a whole.
