  • Ichthyophis is recognized as the most widely distributed genus of the caecilian amphibians.
  • The genus is said to have 50 species, 13 of which occur in India.
  • Ichthyophis multicolor is the ninth species of the region.
  • The species derives its scientific name from a yellowish lateral stripe which separates its brownish upper part from a paler lower part.

  • Significance:The presence of Ichthyophis multicolor points to northeast India being the dispersal route of various species from South Asia to Southeast Asia.

    • It helps in colonizing new habitats.
  • They are fossorial (burrowing) and secretive.
