Ganges River Dolphin Trivia Questions

Declared in 2009, it represents the health of the Ganges ecosystem. This status highlights its cultural and ecological importance.

Their long, thin beak has sharp teeth that protrude outward, giving a distinct appearance. This helps them grasp slippery fish in muddy water.

They have tiny, pinhole-like eyes with no lens, rendering them practically sightless. Echolocation is their primary survival tool in muddy river waters.

Dolphins are mammals with lungs, not gills or permeable skin. They must surface to breathe; prolonged exposure out of water leads to suffocation.

Estimates suggest around 3,000 to 5,000 remain, though they are endangered. The number is far higher than 100, but still critically low.

They are shy, rarely breaching above the surface. Their surfacing is subtle—just a quick roll to breathe—to avoid predators and stay hidden in murky waters.

Unlike ocean dolphins, they have unfused neck vertebrae, giving them remarkable head mobility to catch prey in shallow, narrow rivers.

Gestation is actually about 8 to 10 months, similar to many other dolphin species. The 18-month myth likely comes from confusion with larger whale species.
