I am reading it’s very rare.They maintain the larval form due to an environmental lack of iodine, which is required to stimulate the thyroid. Laboratory injections of iodine & thyroid stimulating hormone will trigger metamorphosis. Outside the lab, cannibalism and rare exposures to iodine will result in terrestrial animals that don’t fare well. Very rare events.Quite possibly since a small percentage of Axies do continue from larval form to become fully landbased Salamanders
If an Axie is changing form, the tail thins and lengthens, the legs get slightly longer, claws start to form on the toes and the external gill feathers start to regress into the head
What a fascinating animal, this olm. Thanks for the post. Do you think the chart is off? Can they live that long? How can the weight be so low when the they get as long as a axies? Are they very worm like? Amazing how it says they can go 5 MPH. My axies are so slow & I active.Axies have long been labrats...mostly for studies into why they don't always progress from larval form (as Axies) to full Salamander form and the regeneration abilities too....they are truly fascinating animals. There is one other close relative of Axies...the Olm...that are only found in European caves. They are totally blind.
Olm
Enjoy this expertly researched article on the Olm, including where Olm s live, what they eat & much more. Now with high-quality pictures.a-z-animals.com
Saw pics of them online. Some beautiful striped and spotted ones. Very similar otherwise to axotles. Believe they have interbred in labs. Think the University of Buffalo, NY, had them breeding together years ago.We have tiger salamanders here, and once in a while I come across a desert pond that is full of larvae. Guess what they look like? Axolotls! I'm pretty sure axolotls are a form of salamander that, through some genetic mutation, never transform into adults.
Might have been a toadSorry to burst your bubble. But Tom was a frog.
Not unknown according to my sources. An environmental lack of iodine results in thyroid deficiencies. When injected in labs with iodine/thyroid stimulating hormones, they do metamorphosis. Some researchers say staying in water had an evolutionary advantage: more food & fewer predators. The rare out of lab change to the adult form is also due to exposure to iodine, sometimes by cannibalism. Scientific American has a series of articles on them.Axies are Salamander who do not move from larval stage to adult....an Axie is a fully aquatic animal, must never be out of water.
It is still unknown as to why the Axies and Olms stay as larval forms but instead of progressing to landbased Salamander they just stay as a baby and regenerate when hurt or attacked...they regenerate everything, including their brain, when damaged.
Yes they can live that long. They live 70+ in Zoo easily.What a fascinating animal, this olm. Thanks for the post. Do you think the chart is off? Can they live that long?
