An endemic family only living on Mahe and Silhouette, with a unique way of reproduction, living 250 meters and higher in the tropical rainforest of the Seychelles.  

 

 This are the 4 Sooglossidae edited on stamp in February 2003

 

Sooglossus seychellensis

S.seychellensis.jpg (85666 bytes)Is a mist-forest frog, 3 to 4 cm long living above 400 meters. The eggs are laid on land on a flat humid surface. The male guards the eggs until they hatch. The small tadpoles wriggle up his back, and stay there, consuming their big yolk sacs until they metamorphose, and jump off his back as mini-adult frogs.

Sooglossus gardneri

S.gardneri.jpg (94329 bytes)Is one of the smallest frogs in the world, maximum 11 mm, and can be found from 200 meters and higher, dwelling the forest floor. Similar to S. seychellensis the eggs are laid on land on a flat humid surface, but contrary to S. seychellensis, they don’t have a tadpole phase, but hatch as tiny adult frogs

Sooglossus pipilodryas
 

This little frog was recently discovered by dr. Justin Gerlach. It has about the same size as S. gardineri, more information is very scarce. Until now they were only found in the leaf pits from  young palm trees in    the high mountain forest of Silhouette.
