They are generally not restricted to specific foods, but feed on almost any organism of a reasonable size. [37] Large species such as the Japanese giant salamander (Andrias japonicus) eat crabs, fish, small mammals, amphibians, and aquatic insects. [38]
[15] [16] The common mudpuppy never leaves its aquatic environment and therefore does not undergo morphogenesis; however, many salamanders do and develop differentiated teeth. [17] Aquatic salamander teeth are used to hinder escape of the prey from the salamander; they do not have a crushing function. [17] This aids the salamander when feeding.
Even though they eat fish eggs, negative effects on fish populations have not been documented. Fishermen have been known to catch mudpuppies, sometimes in large numbers, but most often when ice fishing. [7] Necturus salamanders also commonly feed on mollusks, worms, insects and small fish. [8]
These salamanders eat a variety of things which include insects, insect larvae, spiders, beetles, millipedes, snails, slugs, mollusks and large quantities of earthworms.
This hunting tool is made with a combination of bamboo and sharp hooks baited with frogs or smaller fish. This is used to capture the salamander and keep it alive. Some hunters use pesticides to kill the salamander. Farmers often poach wild salamanders to stock their breeding programs, while others are hunted as food.
C. alleganiensis feeds primarily on crayfish and small fish, but also insects, worms, molluscs, tadpoles and smaller salamanders. [39] [40] A study conducted in 2017 found that larval hellbenders eat mayfly and caddisfly nymphs. [41]

This can include tadpoles, fish, and other salamanders. Adults usually feed on terrestrial vertebrates and invertebrates. They will eat things as large as shrews, mice, and small snakes, along with other salamanders. They will eat anything that they can catch. Fish, weasels, water shrews, and garter snakes are a few of their predators.
