10. Larval Stages of Amphibians at Lackunda Estate, Coorg Katie Hampson and Daniel Bennett

Nothing is known about the larval stages of most amphibians in India, so we collected eggs and larvae around Lackunda. At various satages of development specimens were taken, preserved in alcohol and deposited at the Zoological Survey of India, Calcutta. Drawings were made of all stages and where possible photographs taken. Where possible species were reared from eggs of known origin, or reared to a stage where identification was possible. Given limited time it was not possible to rear each species from egg to metamorph.

The tadpoles were reared in small water-filled plastic containers, kept in the shade, fed daily on dry fish food and water changed daily. A few species would not feed on fish food and so were provided with alternatives such as pond weed and small epices of meat. Large species such as Rana curtipes were reared in buckets.

The following drawings illustrate dimensions (snout vent length, tail lenth and head width), the tadpole shape, distinctive features, markings and colours are described.

It is recommended that they breeding strategy and larval stages be investigated for those species not illustrated in this report, and that the complete larval stage development process is illustrated where this is lacking.
