Question 1

True or false: The Ganges River dolphin is India's national aquatic animal.

Accepted Answer

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

Question 2

True or false: The Ganges River Dolphin has a unique, elongated snout with teeth that are visible even when the mouth is closed.

Accepted Answer

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

Question 3

True or false: Ganges River dolphins are functionally blind and use echolocation to navigate and hunt.

Accepted Answer

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

Question 4

True or false: Ganges River dolphins frequently leap high out of the water like their ocean cousins.

Accepted Answer

False. 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.

Question 5

True or false: As of 2020, fewer than 100 Ganges river dolphins remained in the wild.

Accepted Answer

False. The IUCN estimated 3,500–5,000 individuals in 2020, far more than 100.

Question 6

True or false: Ganges River Dolphins can survive for hours out of water by breathing through their skin.

Accepted Answer

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

Question 7

True or false: Ganges River dolphins have a flexible neck that allows them to move their head sideways like a snake.

Accepted Answer

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

Question 8

True or false: Female Ganges River dolphins carry their young for over 18 months before giving birth.

Accepted Answer

False. 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.
