Newts, small amphibians resembling both lizards and frogs, belong to the Salamandridae family that consists of over 60 species. These fascinating creatures are found throughout the Northern Hemisphere, including North America, Europe, Asia, and North Africa, with a majority of them dwelling on land rather than spending their entire lives in or near aquatic environments such as swamps, grasslands, and croplands.
Although they appear cute and harmless, newts are actually carnivorous and can be quite dangerous. Their diet, habitat, and unique features, such as their limbs and sticky tongue, make them an interesting species to explore. During the breeding season, the courtship behaviors of males and females can be observed in ponds, their preferred habitat. Examining the size, colors, and predators of newts can provide insights into the daily challenges and adaptations they face in their environment, often hiding under logs and stones for protection.
What Do Newts Eat?
Newts, being carnivorous creatures, consume a variety of animal protein found both on land and in water. Their diet consists of insects, tadpoles, worms, shrimp, and slugs, among other small invertebrates, depending on their habitat.
While on land, newts primarily eat:
- Insects
- Slugs
- Snails
- Worms
- Mites
- Crane flies
- Spiders
- Springtails
- Amphibian eggs
Being nocturnal beings, newts seek shelter during the day under stones, logs, compost heaps, and other dark, moist areas.
In aquatic environments, newts find solace in underwater vegetation, where they consume:
- Aquatic insects
- Mosquitoes
- Tadpoles
- Water snails
- Small crustaceans, such as shrimps
- Insect larvae, including mosquito and mayfly nymphs
- Seed shrimps
- Leeches
- Aquatic beetles
- Millipedes
- Water-dwelling insects, such as bees, wasps, ants, and sawflies
Newt larvae, during their adolescent stage, feed on small shrimp and insect larvae they encounter while swimming. This variety of diet helps newts thrive in both terrestrial and semi-aquatic habitats, ensuring they maintain a well-rounded consumption of nutrient-rich prey.
How Do Newts Hunt For Food in the Wild?
Newts employ a combination of active and passive predation when hunting for their food. In active predation, newts actively chase their prey, while passive predation involves lying in wait and ambushing unsuspecting victims.
These adaptable creatures have a rather simple approach to hunting: if it moves and can be swallowed, it’s fair game. They enjoy a wide variety of prey, including large earthworms. However, sometimes newts misjudge the size of their intended meal and struggle to fully consume the large prey. In such situations, they ultimately release the prey from their mouths.
As nocturnal hunters, newts mainly search for food during the night, making the most of their stealthy hunting techniques.
What Do Newts Eat as Pets?
Newts have varying dietary preferences depending on their species and whether they are aquatic or terrestrial. As a newt owner, your goal is to mimic their natural diet as closely as possible, ensuring they receive the necessary nutrients.
Aquatic newts enjoy a diverse menu including:
- Plankton
- Mosquito larvae
- Insects
- Mealworms
- Bloodworms
- Brine shrimp: an excellent addition to their diet as it offers variety.
- Nightcrawlers
- Frozen fish
- Fish food
Though newts prefer live prey, they can be trained to eat dead ones as well. While mealworms are a good option, other live prey may offer more nutritional value.
For terrestrial newts, their diet primarily consists of:
- Crickets
- Mealworms
- White worms
Feeding your newt insects that have been enriched with calcium is an excellent choice to ensure a healthy diet.
Maintaining a diet similar to their natural one can be challenging for captive newts, especially larger aquatic ones. Offering live feeder fish to adult aquatic newts can help satisfy their dietary needs and provide enrichment. Remember to closely monitor your pet newt’s preferences and adapt their diet accordingly, ensuring their well-being and happiness.
How Often Do Newts Eat?
Newts have different feeding frequencies depending on their age. While adult newts can be fed twice a week, it is essential to feed juvenile newts daily to ensure their proper growth. In both cases, it is crucial to always provide them with fresh, clean, and chlorine-free water. During spring, newts may need more food to help them fuel their increased activity during the mating season.

What Supplements Do Newts Need in their Diet?
While newts may not have access to supplements in their natural habitat, it’s essential to provide your pet newt with calcium and a multivitamin supplement. These should be given at least once or twice a week to promote their overall well-being.
- Calcium: Both amphibians and reptiles need calcium in their diet for maintaining strong bones and overall health.
- Multivitamin supplement: Alongside calcium, providing a multivitamin supplement ensures that your newt receives a well-rounded and nutrient-rich diet.
By incorporating these supplements, you can ensure a long and healthy life for your newt.
Are Newts Dangerous to Humans?
Newts possess the ability to alter their skin color as a way to blend in with their environment and avoid predators. Some newts produce toxic mucus as a defense mechanism, and their bright colors serve as a warning to predators about their toxicity. A study published in Toxicon in 1966 discovered the presence of tetrodotoxin (also known as tarichatoxin) in at least 10 newt species, revealing that these seemingly harmless creatures can be quite dangerous under certain circumstances.
While newts can exhibit toxic properties, they are not inherently dangerous to humans if housed in appropriate habitats and handled with care. It is essential to understand and respect the potential hazards associated with these fascinating creatures and exercise caution in their presence.
Remember, the key to safely coexisting with newts is awareness and proper handling to ensure that their toxicity does not pose a risk to humans.
