# Ray-Finned Fishes (*Actinopterygii & Sarcopterygii*)

> Hydrodynamic aquatic rulers with lateral line pressure sensors, swim bladders, and electrical weaponry.

Bony fishes represent the most diverse vertebrate group on the planet. Maneuvering via ray-supported fins and neutrally buoyant swim bladders, they inhabit everything from high-altitude mountain streams to abyssal ocean trenches past 8,000 meters deep.

## Key Evolutionary Adaptations

- Lateral line sensory systems detect water displacement and pressure waves from surrounding swimming creatures.
- Electric eels align 6,000 electrocyte cells in series to discharge predatory shocks up to 860 volts.
- Coelacanths possess fleshy lobed fins containing internal bone structures ancestral to all four-legged land animals.
