Allocaudata
Allocaudata is an order of amphibians that includes the cryptobranchid salamanders, commonly known as giant salamanders. These large, aquatic creatures have elongated bodies, flattened heads, and well-developed limbs. They are primarily found in North America and Asia, inhabiting freshwater rivers and streams. Giant salamanders are known for their unusual reproductive behavior, which involves the male guarding the eggs until they hatch.
