Saw this mating seen of Himalayan Toad at a village named Tinchuley near Takdah forest in Darjeeling. The mating lasted for three days. The amplexus of Toads are about ten types.
1. Inguinal - Male clasps female with forelimbs around her waist. Vents are not close to each other. This category includes pelvic amplexus.
2. Axillary - Male clasps female with forelimbs at the level of her shoulders or under her forelimbs. Male and female vents are close to each other. In some species male is also glued.
3. Cephalic - Male clasps female pressing under her jaw, or either side of her head.
4. Gular - Male clasps female exclusively around her throat
5. No Amplexus - Absence of mating grasp between male and female.
6. Glued - Male is attached to the posterior part of the female body. He is 'glued' to the female by a mucus skin secretion.
7. Dorsal straddle - Contact without clasping. Male sits on the back of the female and press her against a substrate.
8. Head Straddle - Contact without clasping. The male sits on the back of the head of the female, allowing his sperm to runs on her back.
9. Loose amplexus - Male on the back of the female but without clasping her.
10. Scapular amplexus - Male on the back of the female, pressing his fits into each side oh the female vertebral column.
This is Axillary amplexus. The protruding tongue of female probably because of tight grasp of male, more study needed. I'll share a detail trip report in future.
