Climbing species have elongated, square-tipped toes, while rock-dwellers have larger feet with short, blunt toes. The tree-climbing salamander (Bolitoglossa sp.) has plate-like webbed feet which adhere to smooth surfaces by suction, while the rock-climbing Hydromantes species from California have feet with fleshy webs and short digits and use their tails as an extra limb.

Some aquatic species, such as sirens and amphiumas, have reduced or absent hind limbs, giving them an eel-like appearance, but in most species, the front and rear limbs are about the same length and project sideward, barely raising the trunk off the ground. The feet are broad with short digits, usually four on the front feet and five on the rear. Salamanders do not have claws, and the shape of the foot varies according to the animal's habitat.

An adult salamander generally resembles a small lizard, having a basal tetrapod body form with a cylindrical trunk, four limbs, and a long tail. Except in the family Salamandridae, the head, body, and tail have a number of vertical depressions in the surface which run from the mid-dorsal region to the ventral area and are known as costal grooves. Their function seems to be to help keep the skin moist by channeling water over the surface of the body.

Salamanders range in size from the minute salamanders, with a total length of 27 mm (1+1⁄8 in), including the tail, to the Chinese giant salamander which reaches 1.8 m (6 ft) and weighs up to 65 kg (145 lb). All the largest species are found in the four families giant salamanders, sirens, Congo eels and Proteidae, which are all aquatic and obligate paedomorphs.

Some of the largest terrestrial salamanders, which go through full metamorphosis, belong to the family of Pacific giant…

The skin lacks scales and is moist and smooth to the touch, except in newts of the Salamandridae, which may have velvety or warty skin, wet to the touch. The skin may be drab or brightly colored, exhibiting various patterns of stripes, bars, spots, blotches, or dots. Male newts become dramatically colored during the breeding season. Cave species dwelling in darkness lack pigmentation and have a translucent pink or pearlescent appearance.

Salamanders typically lay eggs in water and have aquatic larvae, but great variation occurs in their lifecycles. Some species in harsh environments reproduce while still in the larval state.

The word salamander comes from Old French salamandre from Latin salamandra from Greek salamándra used specifically for the fire salamander; it is of uncertain, possibly, pre-Greek origin.

This has made salamanders an invaluable model organism in scientific research aimed at understanding and achieving regenerative processes for medical advancements in human and animal biology.

The skin of some species contains the powerful poison tetrodotoxin; these salamanders tend to be slow-moving and have bright warning coloration to advertise their toxicity.

The remarkable ability of salamanders to regenerate is not just limited to limbs but extends to vital organs such as the heart, jaw, and parts of the spinal cord, showing their uniqueness compared to different types of vertebrates.

This ability is most remarkable for occurring without any type of scarring. ⁤⁤

This group of amphibians is capable of regenerating lost limbs as well as other damaged parts of their bodies. Researchers hope to reverse engineer the regenerative processes for potential human medical applications, such as brain and spinal cord injury treatment or preventing harmful scarring during heart surgery recovery.

Salamanders never have more than four toes on their front legs and five on their rear legs, but some species have fewer digits and others lack hind limbs.

Their permeable skin usually makes them reliant on habitats in or near water or other cool, damp places. Some salamander species are fully aquatic throughout their lives, some take to the water intermittently, and others are entirely terrestrial as adults.

Urodela is a scientific Latin term based on the Ancient Greek οὐρά δήλη: ourà dēlē "conspicuous tail". Caudata is the Latin for "tailed ones", from cauda: "tail".

Salamander diversity is highest in eastern North America, especially in the Appalachian Mountains; most species are found in the Holarctic realm, with some species present in the Neotropical realm.

Salamanders are a group of amphibians typically characterized by their lizard-like appearance, with slender bodies, blunt snouts, short limbs projecting at right angles to the body, and the presence of a tail in both larvae and adults.

All ten extant salamander families are grouped together under the order Urodela, the sole surviving order from the group Caudata.

Strawberries are low in calories, delicious, and healthy.

They are a good source of many vitamins, minerals and plant compounds — some of which have powerful health benefits.

The health benefits include reduced cholesterol, blood pressure, inflammation, and oxidative stress.

Furthermore, these berries may help prevent big spikes in both blood sugar and insulin levels.

Strawberries are an excellent addition to a healthy diet.

The allergy-causing protein is believed to be linked to strawberries’ anthocyanins. Colorless, white strawberries are usually well tolerated by people who would otherwise be allergic.

Furthermore, strawberries contain goitrogens that may interfere with the function of the thyroid gland in people with thyroid problems.

Strawberries are usually well tolerated, but allergy is fairly common — especially in young children.

Strawberries contain a protein that can cause symptoms in people who are sensitive to birch pollen or apples — a condition known as pollen-food allergy.

Common symptoms include itching or tingling in the mouth, hives, headaches, and swelling of the lips, face, tongue, or throat, as well as breathing problems in severe cases.

The protective effects of strawberries may be driven by ellagic acid and ellagitannins, which have been shown to stop the growth of cancer cells.

More human research is needed to improve the understanding of the effects of strawberries on cancer before any solid conclusions can be reached..

Strawberries may decrease your risk of heart disease and cancer, as well as help regulate blood sugar.

Cancer is a disease characterized by uncontrolled growth of abnormal cells.

Cancer formation and progression is often linked to oxidative stress and chronic inflammation.

A number of studies suggest that berries may help prevent several types of cancer through their ability to fight oxidative stress and inflammation.

Strawberries have been shown to inhibit tumor formation in animals with mouth cancer and in human liver cancer cells.

Strawberries seem to slow down glucose digestion and reduce spikes in both glucose and insulin following a carb-rich meal, compared to a carb-rich meal without strawberries.

Thus, strawberries may be particularly useful for preventing metabolic syndrome and type 2 diabetes.

When carbs are digested, your body breaks them down into simple sugars and releases them into your bloodstream.

Your body then starts secreting insulin, which tells your cells to pick up the sugar from your bloodstream and use it for fuel or storage.

Imbalances in blood sugar regulation and high-sugar diets are associated with an increased risk of obesity, type 2 diabetes, and heart disease.

According to a study in middle-aged people with well-established risk factors for heart disease, berries may improve HDL (good) cholesterol, blood pressure, and blood platelets function.

Strawberries may also:
improve blood antioxidant status
decrease oxidative stress
reduce inflammation
improve vascular function
improve your blood lipid profile
reduce the harmful oxidation of LDL (bad) cholesterol

Ellagitannins and ellagic acid comprise a large part of these antioxidants in strawberries.

They have received considerable attention and have been linked to numerous health benefits. This includes fighting bacteria and a reduced risk of cancer.

The main ellagitannin in strawberries is sanguiin H-6.

Strawberries contain high amounts of beneficial plant compounds and antioxidants, such as pelargonidin, ellagic acid, ellagitannins, and procyanidins.
