Why do eels remain suspended upright in water?

Eels remain suspended upright in water due to their unique body structure and buoyancy control. Their elongated, flexible bodies allow them to adjust their position easily, while a swim bladder, when present, helps regulate buoyancy. This enables them to maintain a stable position in the water column, conserving energy while they search for food or evade predators. Additionally, their muscular movements facilitate fine adjustments in orientation and depth.
