Pacific Giant Salamander

Growing to lengths of 35cm the Pacific Giant Salamander (Dicamptodon tenebrosus) is the largest salamander in British Columbia. The larvae are completely aquatic and can reach 12-13cm in length. Some larvae, known as Neotenes, develop reproductive maturity yet retain larval physiology and also grow to 35cm in size and remain totally aquatic. Adults are primarily terrestrial foragers, and will prey upon anything it can overpower and fit in its mouth – anything from beetles, spiders, and slugs to shrews, mice, and even other salamanders. In British Columbia the pacific giant salamander faces extensive habitat loss due to timber harvesting and development. The salamander larvae require cold shaded streams with un-silted pools to develop. Even the cleanest logging practices or any disturbance can cause turbidity in the water making it unsuitable for the larvae. Once fully developed adults don’t disperse far from where they’re born, making the recovery of this species even more challenging.
