The scientific names of the newly-discovered fish species are Mystus prabini, found in Sinkin and Dibang rivers in Lower Dibang Valley district and Exostoma kottelati, found in Ranga river in Lower Subansiri district, a release by the university said.

Other discovered species are Creteuchiloglanis tawangensis, found in the Tawangchu river in Tawang district, Garra ranganensis, found in Ranga river and Physoschistura harkishorei, found in Dibang and Lohit rivers in Lower Dibang Valley district, it said.

The team was led by Prof D N Das of the fisheries and aquatic ecology research wing of the Zoology department of the university.

“Majority of the water bodies in remote areas of the state are still not easily accessible to the researchers due to a difficult terrain that includes rain forests, steep hills besides communication problems,” Das said.

He, however, said his research team is optimistic that meticulous exploration may result in more discoveries of new fish species from the state in the future.

For the first time, a rare rhino was born by artificial insemination at the Miami zoo

For the first time a rare rhino was born thanks to artificial insemination. The Indian rhino mother Akuti gave birth to a healthy young rhino at the Miami Zoo last Tuesday. It is the first Indian rhino born by artificial insemination.

The little rhino, whose gender is still unknown, was born at half past twelve in the afternoon and is the first little one of Akuti, a seven-year-old single-horned Indian rhino. The father is Suru, an eighteen-year-old Indian rhino. Both mother and baby are doing well. Both still have to be examined by a veterinary team which is only done when the staff consider it safe to separate the little one from his very protective mother for a few minutes, according to a spokesperson for the zoo.

No natural fertilization

Akuti (meaning “princess” in Hindi) did not get pregnant, despite several attempts at natural fertilization. That is why a team of experts was brought to the Miami zoo that started the artificial insemination process in January last year.

As soon as it became clear that Akuti was indeed pregnant, the rhino was trained to accept ultrasound. In this way the employees could keep a close eye on the growth and birth of the young.

Indian rhinos are on average between 15 and 16 months pregnant and the mothers can give birth to a calf once every two or three years. Akuti and her baby cannot yet be seen in public at the zoo, that only happens when the two are used to each other.

The Indian rhino is very popular among poachers because of its horn. There are approximately 3500 Indian rhinos in the world, according to the International Rhino Foundation. The Miami zoo is therefore very happy with the birth of the baby rhino: “This very rare birth is not only significant for Zoo Miami, it is incredibly important to the international efforts to maintain a healthy population under human care of this highly vulnerable species throughout the world.”

It is not the first time that an endangered species is artificially fertilized. Earlier, an elephant, a crocodile and a giant panda became pregnant via this route.
