Scientists have discovered a new species of crab — Vela carli — that exhibits characteristics of both male and female, a condition known as gynandromorphism. This dual-sex crab species was discovered in India and adds to the understanding of reproductive biology in crustaceans. Gynandromorphism is an extremely rare biological phenomenon where an organism contains both male and female tissues, typically resulting from genetic anomalies during early cell division. The discovery was published in a peer-reviewed journal and has generated interest among marine biologists studying sex determination mechanisms in decapod crustaceans.

Specimens of the freshwater crab species Vela carli recently observed in Silent Valley National Park exhibited which rare biological condition?
Explanation · Correct answer C
Researchers reported rare gynandromorph specimens of Vela carli from Silent Valley National Park. Gynandromorphism means that an individual shows both male and female characteristics, usually because of unusual events during early development.

Frequently asked questions
What is the new dual-sex crab species Vela carli discovered in India?
**Vela carli** is a newly discovered crab species found in **India** that exhibits characteristics of both **male and female** simultaneously — a rare condition known as **gynandromorphism**. The discovery was published in a **peer-reviewed journal** and is significant for the study of reproductive biology in crustaceans.
What is gynandromorphism as seen in the Vela carli crab species?
**Gynandromorphism** is an extremely rare biological phenomenon where an organism contains **both male and female tissues** in the same body. In **Vela carli**, this results from **genetic anomalies during early cell division** and is being studied to understand **sex determination mechanisms** in decapod crustaceans.
Where was the dual-sex crab species Vela carli discovered?
The dual-sex crab species **Vela carli** was discovered in **India**. The discovery adds to scientific knowledge of **reproductive biology in crustaceans** and has generated significant interest among **marine biologists** studying sex determination in **decapod crustaceans**.
Why is the discovery of Vela carli scientifically significant?
The discovery of **Vela carli** is significant for three reasons: - It is a **new species** added to India's biodiversity record - It demonstrates **gynandromorphism** — an extremely rare biological condition - It advances understanding of **sex determination mechanisms** in decapod crustaceans
What causes gynandromorphism in crab species like Vela carli?
**Gynandromorphism** in species like **Vela carli** is typically caused by **genetic anomalies during early cell division**, resulting in an organism that carries both **male (XY) and female (XX) genetic material** in different tissues. This is an extremely rare occurrence studied by marine biologists and geneticists.
