Sonar Visualizer sneak peek

Watch a pulse ripple across the ocean grid, then launch the full game to guide a dolphin toward its pod using returning echoes.

  • See how sound waves reflect off reefs and fish.
  • Practice timing bursts for maximum clarity.
  • Earn streak bonuses for smooth navigation.

Sound lab

Contrast clicks and whistles

Play each sample to hear how dolphins shift between rapid-fire navigation clicks and melodic signature whistles.

Clicks for mapping

Short, bright bursts help dolphins find fish and avoid obstacles. Ask learners to count the beats between echoes.

Whistles for names

Smooth, sliding tones carry personal IDs. Challenge listeners to mimic the rising pitch to remember a podmate’s name.

Tip: When one track is playing, the other will pause so your group can focus on a single sound texture at a time.
