Axolotl: Axolotl care, tanks, habitat, diet, buying, life

Shrouded in mystery, and defying typical biological laws like metamorphosis, the axolotl pronounced AX-oh-lot-ul , a type of salamander, keeps its webbed feet firmly placed in infancy throughout its life.

The axolotl remains aquatic like larvae their entire life. Like youngsters, they retain external gills, a tail, and a body fin, and lack moveable eyelids. Indigenous to these two spring-fed lakes along the southern edge of the Basin of Mexico, much of its suitable habitat has been drained. The Xochimilco-Chalco basin, once about 77 square miles square kilometers of marshes, swamps, and lagoons, was significantly reduced 85 years ago when drainage projects were completed.

This situation is surprising, given the popularity of the axolotl for scientific study. Salamander superpowers. Axolotls are dark-colored and can shift their hue a few shades lighter or darker as needed for camouflage!

They are also used in laboratories to study another superpower: regenerating their limbs, lungs, heart, jaws, spines, and even parts of their brain! Scientists have found that axolotls can regrow a new limb five times perfectly, in a few weeks—without even a scar.

Every tissue is replaced: skin, bone, cartilage, muscle, and stem cells. Other organs can regenerate countless times and be completely functional. Naturally, scientists would like to harness that ability and apply it to human medicine.

Baby face. An axolotl can reach 18 inches in length, but nowadays grows to about 9 inches. Axolotls are dark-colored with greenish mottling; some may have silvery highlights on the skin. It has a broad, flat body with a large head donning its signature feathery gills waving gently in the water.

Its mouth is often bent into a slight grin or is otherwise expressive. Round, dark eyes with yellow, iridescent irises take in its murky environment. It has lizard-like limbs that carry it along the lake bottom. It weighs about as much as a can of soup. In a pinch, the axolotl can move an astonishing 10 miles per hour 15 kilometers per hour.

Lake view. It is hoped that these amazing creatures will breed and thrive. A Day in the life. Despite their infantile charm and undeveloped teeth, axolotls are effective predators, inhaling worms, mollusks, crustaceans, insect larvae, and even small fish!

During the day, they burrow into the aquatic vegetation and mud to avoid being eaten, and at night they become animated…and hungry. While they use their gills to breathe underwater, they may pop up to the surface for a quick gulp of air from time to time.

Do the axolotls benefit from a varied diet or eating the same thing day after day? One recent study compared three different diets: bloodworm invariant ; Daphnia a small aquatic crustacean invariant ; and a mixture of these two prey items.

The juvenile axolotls grew fastest on the bloodworm diet and slowest on the Daphnia diet, with a mixed diet resulting in intermediate growth rates. Thus, a mixed diet, as humans might prefer, may not be beneficial to the growth or welfare of axolotls as compared with a proper, high-quality, invariant diet.

Hoover dining. Using a suction technique, the axolotl consumes worms, tadpoles, insects, and small fish.

Gravel may also get inhaled, which helps grind up its food in its belly just as birds use grit to break down food for digestion.

Stay safe. The axolotl has few predators in the wilderness, though they may be taken by storks and herons, as well as large fish carp and tilapia , on occasion. Predation from introduced fish and large birds, as well as over-collecting them for food and medicine also contributes to their persistent decline. Waltz with me. Axolotls reach sexual maturity by six months of age, followed by a breeding season between March and June, when water temperatures and levels are more temperate. A waltz between a male and female initiates mating.

She lays her eggs individually, placed on plants or rocks to avoid predators. Two weeks later, the eggs hatch and the youngsters are off and running…well, swimming.

There is no parental care, so they figure it out as they go. The Spanish word for axolotl is ajolote, but is used colloquially in Mexico to encompass all forms of salamander. It is also called the Mexican walking fish though it is not a fish at all. While the axolotl retains larval characteristics into adulthood, it can be prompted into metamorphosis in a laboratory setting with the injection of hormones. The axolotl is part of the group of mole salamanders—which includes its closest relative, the tiger salamander Ambystoma tigrinum ; and the more distant relative, the spotted salamander Ambystoma maculatum.

Biology’s beloved amphibian — the axolotl — is racing towards extinction

So be sure to use the buttons in the table of contents to help navigate the article to information you need. As a result, huge numbers of axolotls were killed while the remainder began populating the canals of Xochimilco. Wild-Type: Mottled green with bright eyes purple gills. Two axolotls would require 20 gallons, three would need 30, and so on and so forth you get the drift.

Instead of taking to the land, adults remain aquatic and gilled. Axolotls should not be confused with waterdogs , the larval stage of the closely related tiger salamanders A. Neither should they be confused with mudpuppies Necturus spp.

Repto-min , trout chow or salmon chow serves well as a mainstay; alternate this with Hikari Massivore Delight or a pelleted cichlid food , freeze dried prawn , live blackworms, earthworms, minnows, shiners and guppies. Axolotls will also take frozen clams, mussels and similar foods, but marine-derived items should not be used as a major part of the diet. Although normally bottom feeders, well-habituated axolotls will rise to the surface to eat, and take readily to hand- feeding.
