Aquatic life

For generations, naturalists have grappled with the enigmatic question of which part of a sea star, often referred to as a "Starfish," constitutes its head. When examining a worm or a fish, it's readily apparent which end serves as the head and which as the tail. However, the sea star, boasting five identical arms, each capable of leading its movement across the ocean floor, has left this conundrum unresolved. The sea star's peculiar body structure has left some to ponder whether it possesses a head at all.
