Salamanders and Newts

Popular as pets, salamanders and newts are amphibians that resemble lizards, but are actually very different. There are over 500 species of salamanders. Ask questions about their diet, habitat and behavior here.

1,005 Questions

What is the process called when a salamander grows a new tail?

The process is called regeneration, where a salamander is able to grow a new tail to replace one that has been lost or damaged. This ability is due to the presence of stem cells in their body that have the capacity to develop into different cell types needed for tissue regrowth.

What does an Eastern Hellbender eat?

Crayfish and small fish are the main food items consumed by Hellbenders. This diet changes little seasonally. They also eat mollusks, worms, and insects. Specimens have been found containing lamprey, tadpoles, aquatic reptiles, and even one containing a toad and another with a small mammal. Adults will eat their shed outer skin, their own eggs, the eggs of others, and even hatchlings of their own species, along with other adults smaller than them.

Why pea root cells and salamander kidney cell takes the same for mitosis?

Pea root cells and salamander kidney cells take the same amount of time for mitosis because they both undergo similar stages of cell division, including prophase, metaphase, anaphase, and telophase. The duration of mitosis is typically consistent across different cell types in a species due to the regulated control of cell cycle checkpoints and the coordination of cellular machinery involved in mitosis.

How many chromosomes does a spotted salamander have?

almost all salamanders have 24 chromosomes. I don't believe it is any different for the "spotted"- most likely wild type- creature you have described.

What are salamaders?

Salamanders are amphibians with slender bodies, long tails, and moist skin. They are usually found near water sources, as they require moisture to survive. Salamanders come in a variety of colors and sizes, and are known for their ability to regenerate lost limbs.

Why is a salmander classified as an amphibian?

A salamander is classified as an amphibian because it has permeable skin that can absorb oxygen and moisture, and it typically spends part of its life cycle in water and part on land. Amphibians are a class of vertebrates that have these characteristics, along with a larval stage in their life cycle.

What geographical feature is the blue grotto?

The Blue Grotto is a sea cave located on the coast of the island of Capri in Italy. It is known for its vibrant blue and emerald waters due to the sunlight passing through an underwater cavity. The cave is a popular tourist attraction for its unique beauty.

What is the use of test tube in laboratory?

Test tubes are used in laboratories to hold, mix, or heat small quantities of liquids or solids for experimental purposes. They are commonly used for chemical reactions, heating samples, and storing small amounts of materials. Test tubes come in various sizes and are an essential tool in scientific research and experimentation.

Is a newt an omnivore?

All Newts are carnivores in their adult phase.

What hypothesis explains Darwin's theory of how limbless salamanders evolved according to Darwin's theory of nateral selection?

Basically Charles Darwin came up with 4 needed characteristics that allows animals/plants to evolve. While studying in the Galapagos Islands he realized for a specific species to evolve they need:

1) To be isolated (on different continents or by water)

2) Reproduction has to be involved (takes many trial and errors)

3) Natural Selection has to occur (the fittest survive the weakest die...like giraffes and long necks if having a long neck to reach the high leaves in trees is needed they'll survive while the shorter neck giraffes die)

4) Have to correctly be fitted sexually (same number of gametes)

In this case probably it was a salmander that eventually became isolated by water therefore primarily not using any limbs and they kept reproducing while the ones with the longer legs lives became harder to survive from predators. The interesting observation is that several species have developed the limbless response to environmental conditions. Reptiles evolved to become snakes and both lizards and salamanders also developed this trait. Other animals which gave op limbs for increased mobility include whales and dolphins (limbless mammals) and ichthyosaurs (limbless reptiles) which evolved from limbed animals to emulate fish.

How do newts reproduce?

Newts reproduce through internal fertilization, where a male transfers sperm to a female through a specialized structure. The female lays eggs, which are externally fertilized by the male's sperm. The eggs hatch into aquatic larvae, which undergo metamorphosis to become terrestrial adult newts.

What is another name for a newt?

its an aquatic salamander (salamander that lives in water)

What is the hypothesis of a aquatic salamander and a land salamander?

I believe that the hypothesis has something to do with the evolution to the varying ecosystems .in which salamanders live. the aquatic salamander evolved most likely to benefit in its area. A great area that may be referred to for this is Darwin's theory, of natural selection

Genus of salamander with an eel like body and no back legs?

The genus of salamander that fits this description is Siren. Sirens have long, eel-like bodies, no back legs, and are commonly found in aquatic environments in North America. They have gills for breathing underwater and are often mistaken for eels due to their appearance.

What is the scientific name for newt?

  • Taricha granulosa
  • Rough-skinned Newt
  • Taricha torosa
  • California Newt
  • Taricha torosa sierrae
  • Sierra Newt
  • Taricha torosa torosa
  • Coast Range Newt
  • There is only one question what is the scientific name for just a newt.
  • No one knows. Well maybe you do so improve this answer.

Who is salamander drake?

Salamander Drake is a creature card from the Magic: The Gathering trading card game that was first introduced in the Mirage expansion. It is a red creature that has the ability to regenerate, making it resilient in combat.

What does kerosene mean in Fahrenheit 451?

In Fahrenheit 451, kerosene is a flammable liquid used by firefighters to start fires instead of putting them out. The government in the novel has turned books into forbidden items, so firemen are tasked with burning all books they find.

What do fire salamanders eat?

The diet of the fire salamander consists of various insects, spiders, earthworms and slugs, but they also occasionally eat newts and young frogs. In captivity, they eat crickets, mealworms, wax-worms and silkworm larvae.

Are axolotls a sub-species?

The axolotl is a fascinating salamander that stays in its 'baby' form for life! Its unique biology has earned it the title of 'paedomorphic' species. You could say it's a species AND a subspecies, in a way. But the real magic lies in its ability to regenerate lost body parts, including limbs, tail, and even parts of its brain and spinal cord - making it a true marvel of nature! For more information on this creature or other animals you can use as anecdotes or conversation starters, please check out my videos on YouTube (@WiskiWaski). :)

How do newts communicate?

all animals have a way of communicating with other animals of the same species.

Do salamanders need heat?

Salamanders are Poikilothermic. This means that their body temperature is determined by their environment.
