Twenty Red-Crowned Roofed Turtles (Batagur kachuga), which are critically endangered, have been successfully reintroduced into the Ganga River

Overview of Red-Crowned Roofed Turtles (Batagur kachuga):

Scientific Classification: Batagur kachuga

Geographical Distribution:

Countries: India, Nepal, Bangladesh

Rivers: Ganga, Brahmaputra (historical); Chambal (current viable habitat)

Conservation Status:

IUCN (Global): Critically Endangered

Indian Wildlife Act: Schedule I (Highest Protection)

CITES (International Trade): Appendix I (Banned)

Distinctive Characteristics:

Size: Females can reach lengths of up to 56 cm (approximately 2 feet) and weigh around 25 kg (55 lbs), while males are significantly smaller and lighter.

Shell: Their robust, ridged shell enables them to navigate strong currents, and juvenile turtles possess angled undersides (plastron) for added protection.

Snout: They feature a short, slightly pointed snout that facilitates breathing while remaining submerged.

Coloration: During the breeding season, males exhibit vibrant red, yellow, and blue markings on their necks to attract females.

Behavior and Habitat:

Habitat: They inhabit deep, swiftly flowing rivers and require sandy beaches or sandbars for egg-laying.

Diet: They are strict herbivores, consuming only aquatic vegetation and algae.

Reproductive Period: Mating and nesting occur between March and April, coinciding with warmer temperatures.

Egg Laying: Females excavate nests in the sand, laying between 11 to 30 eggs per clutch, which typically hatch after 60 to 70 days.

Challenges:

Habitat Degradation: Pollution, dam construction, and excessive water extraction threaten their riverine habitats.

Nesting Challenges: Sand mining and agricultural activities along riverbanks compromise nesting sites, leaving eggs vulnerable.

Poaching and Trade: Despite legal protections, they are hunted for their meat (considered a delicacy) and shells (used for decorative purposes).
