Kryptoglanis shajii is a cave-dwelling fish species from the order of the catfish-like (Siluriformes). It is the only species in the monotypical genus Kryptoglanis . The species and genus were only described in 2011. The genus name was given because of the hidden life of the fish ( Latin : "crypta" = tunnel, underground passage, "glanis" = catfish), the fashion epithet honors the Fischtaxonomen CP Shaji, who is the study of the fish fauna of the Western Ghats deserves made Has. Type locality of the species is an underground spring in the southern Indian Western Ghats in the district of Thrissur in the state of Kerala . The species was assigned to an independent family at the beginning of 2014 because it is osteologically very different from other catfish families. The fish are possibly more closely related to the real catfish (Siluridae). This is indicated by the reduced palatine bone of both taxa.
features
Kryptoglanis shajii reaches a standard length of a maximum of about 5.9 cm. The body is elongated and flesh-colored. The body height decreases more and more from front to back and is at the level of the pectoral fin attachment 8.5 to 11.7% of the standard length and 1.1 to 2.3% of the standard length at the caudal fin stalk. The cross-section of the body is round between the pectoral fins and laterally flattened further back. A dorsal fin is missing, the anal fin is completely fused with the caudal fin and takes up a large part of the body length as the fin edge. The fin edge is supported by 70 to 74 fin rays. The pectoral fins are fan-shaped. All fins are stingless. The head is flattened and wider than the body. The upward-pointing mouth is surrounded by four pairs of barbels. The lower jaw protrudes clearly. Both jaws are covered with tiny teeth. The eyes are under the skin. The front nostrils are tubular. The fish have eleven Branchiostegal rays . The sideline is complete.
biology
Kryptoglanis shajii lives in underground springs and groundwater flows in rock and laterite soils . Some of the captured females were ready to spawn and had bellies inflated by eggs. Animals kept in aquariums ate worms and Artemia .
