I found this couple in the undergrowth in my friend's garden.They were so much engrossed in their activity that they did not prefer to heed to my attempts in taking their shot.These are the Common Indian Toads or the Black Spine Toads(Duttaphrynus melanostictus) and are quite common near human settlements.

Kingdom: Animalia
Phylum: Chordata
Class: Amphibia
Order: Anura
Family: Bufonidae
Genus: Duttaphrynus
Species: D. melanostictus

These toads are actually in amplexus.
Amplexus (Latin "embrace") is a form of pseudocopulation in which a male amphibian grasps a female with his front legs as part of the mating process.At the same time or with some time delay,he fertilizes the female eggs with fluid containing sperm.

Species Information:(courtesy : Wikipedia)
The Common Indian Toad or Common Asiatic/Asian Toad or Black-spined Toad(Duttaphrynus melanostictus) is a species of toad that is common in South Asia. The species grows to almost 20 cm long. The species breeds during the monsoons and the tadpoles are black. Young toads may be seen in large numbers after the monsoons.
Head with more or less elevated bony ridges, namely a canthal, a pre-orbital, a supra-orbital, a post-orbital, and a short orbito-tympanic; snout short, blunt; inter-orbital space much broader than the upper eyelid: tympanum very distinct, at least two thirds the diameter of the eye. First finger extending generally, but not always, beyond second; toes at least half webbed, with single sub-articular tubercles; two moderate metatarsal tubercles; no tarsal fold. The tarso-metatarsal articulation reaches the tympanum or the eye. Upper surfaces with more or less prominent, often spiny, warts; parotoids very prominent, kidney-shaped or elliptical, more or less elongate.
Yellowish or brownish above, the spines of the warts and the ridges of the head generally black; beneath immaculate or more or less spotted.Male with a subgular vocal sac and black nuptial excrescences on the two inner fingers.These toads are often seen at night under street lamps especially during times when winged termites swarm.They have been noted to feed on a wide range of invertebrates including scorpions. Tadpoles grown in sibling groups metamorphosed faster than those that were kept in mixed groups.Tadpoles have been shown to be able to recognize kin.
