Newt vs Salamander: How to Tell Them Apart

The fastest way to tell a newt from a salamander is to look at three things, in this order. First, check the size. If it is smaller than 5 inches long, it is likely a newt. If it is bigger than 6 inches, it is probably a salamander. Most salamanders grow to at least 7 inches. Second, touch the skin if you can safely do so. Newts feel bumpy or warty, like you are touching fine grains or sand. Salamanders usually feel smoother and damper to the touch. Third, look at the color and pattern. Many newts are bright orange, red, or yellow with black spots or stripes. Most larger salamanders are brown, gray, or dark reddish. If you see a small, bumpy, brightly colored animal near water, you are almost certainly looking at a newt.

Newts are among the smallest amphibians in North America. Adult newts typically grow to 2 to 5 inches from head to tail. Some species, like the Great Crested Newt, can reach up to 6 inches. Salamanders vary much more in size. Many common salamanders grow to 4 to 8 inches long. The larger species can reach 10 to 12 inches or even longer in exceptional cases. The size difference is one of the clearest ways to tell them apart. Newts have a more compact body shape with shorter legs. Their tails are usually about as long as their body. Salamanders often have longer legs and a more streamlined body. Their tails are typically longer than a newt's tail relative to body size. When you compare them side by side, the size difference becomes obvious.

Newts and salamanders both live throughout the United States, but they prefer different habitats within their ranges. Newts are found in most regions from coast to coast. They prefer areas with temporary or permanent ponds, marshes, and wet forests. You are most likely to find newts near water that stays wet year-round or fills with water in spring. Salamanders are even more widespread than newts. Some species are found in every US state. They live in forests, under logs and leaf litter, in caves, and near streams. Many salamanders prefer moist forests and woodland habitats. The ranges overlap extensively, so you might find both species in the same area. In regions where they coexist, newts tend to spend more time in water, while salamanders often stay on land. Visit wildlife habitats in your region to observe either species.

Newts and salamanders have different activity patterns and lifestyles. Newts are both day and night active, though they tend to be most active during the spring breeding season. They spend significant time in water hunting for small invertebrates and tadpoles. Salamanders are primarily nocturnal, meaning they hunt and move around mostly at night. During the day, they hide under logs, rocks, and in leaf litter to stay moist and safe. Salamanders are very sensitive to drying out, so they stay in damp places. Newts are somewhat more tolerant of drier conditions, though they too need moisture. Both animals are carnivorous and eat small bugs, worms, and other tiny creatures. Newts are sometimes more aggressive hunters in water. Salamanders on land are equally fierce hunters of small invertebrates. Their hunting strategies match their environments perfectly.

If you spot a small amphibian and want to figure out which one it is, use these steps. First, check the location. If you saw it in water or right at the water's edge, it is more likely to be a newt, especially if there is a pond or marsh nearby. If you saw it in a forest under a log or rock, it is more likely to be a salamander. Second, look at the skin carefully. Touch it if you can safely do so. Bumpy or warty skin means newt. Smooth moist skin means salamander. Third, check the color. Bright colors like orange, red, or yellow with black spots or stripes suggest newt. Brown or dark colors suggest salamander. Finally, if you are in a spring forest after rain, you are more likely to see salamanders. In spring ponds, you will find salamanders and newts together. Consider the wildlife habitat around you as a major clue.

Several myths exist about newts and salamanders. One myth is that newts are just baby salamanders. This is not true. Newts are a distinct group within salamanders that stay small their entire lives. They do not grow into larger salamanders. Another myth is that all newts are poisonous. Some newts do have toxic skin, but not all species. The toxin tastes bad and protects the newt from predators, but touching it is usually safe. You should always wash your hands after touching any wild amphibian. A third myth is that salamanders are lizards. Salamanders are amphibians, not reptiles. They breathe through their skin and need moisture to survive. Lizards are reptiles with scales and claws. A final myth is that you cannot find newts and salamanders at the same time. In many parts of the US, you can find both species in the same pond or forest. They coexist in countless locations across the country.
