The Chinese giant salamander is considered to be a â living fossil .â This species is classified as critically endangered in the IUCN Red List because of a massive population decline of more than 80% since the 1950s.ccording to a recent study, 90% of the Chinese giant salamandersâ habitat was destroyed by the year 2000, and there are many human-related causes of such massive destruction. Because the salamander dwells in free-flowing streams, industrialization is a large problem for many stream-dwelling species.
