Gonna warn ya…this might be a long one. So instead of doing my usual introduction, I will start out by saying that we will be covering Dr. Shrunk the axolotl today, because today is April 1st and it’s just too perfect for me to miss out on. Dr. Shrunk has quite the journey during his professional career from AC Wild World to New Leaf. He’s a psychologist (so the Dr. title is real!), then a not funny comedian, and then the owner of ClubLOL. No matter where he’s working, though, his main job was to unlock emotions for the player to use, so explains why he’s not in New Horizons - the villagers stole his job.

They really went to town making Dr. Shrunk an accurate axolotl. (And don’t be surprised if you’re not pronouncing that right; I can’t either.) Of course, I will explain! See, the axolotl is actually a type of salamander, meaning that it is an amphibian. Amphibia, the class of the amphibians, are a group of tetrapods that, unlike all other extant tetrapods (mammals, reptiles, and birbs), they rely on water for at least part of their life cycle. Their eggs do not have hard, protective shells, so they can dry out very quickly. Amphibians also typically start life as larvae, just like fish do. The larvae have gills, but metamorphose into adults with lungs. Well…most do. The axolotl, Ambystoma mexicanum, doesn’t!

Axolotl adults still have their gills, which are the pink feathery stalks on either side of their head, and live their whole lives underwater, just like other amphibian larvae do. This retention of “juvenile” traits is called neoteny, which is the mechanism by which the animal’s body has slowed or delayed their physical development into adulthood. Meaning, they still look like “kids”, and that’s called paedomorphism. They do have an “adult color” of darker olive brown with gold speckling in the wild, but captive breeding has led to other color variants, of which, Dr. Shrunk doesn’t resemble any that I can find. He is most likely based off the leucistic variety, which is white with black eyes, as shown above. They have pretty weak limbs, too, which is featured on Dr. Shrunk and his tiny bent legs.

Despite the fact that the axolotl may be the most famous salamander out there, as it is a popular exotic pet, in the wild it’s considered Critically Endangered. The axolotl is native to Mexico, and at one time, its range extended throughout the wetlands and lakes of the Central Mexico Valley. However, it’s disappeared from most of that, now occupying a 467 square kilometer area within Mexico City. I can’t even begin to tell you how incredibly tiny that area is. Living as a sensitive freshwater species has all downsides as their remaining habitat is threatened by multiple factors, like pollution, development, and invasive species. Maybe one day the axolotl may only exist in captivity…and that’s no laughing matter.

And there you have it. Fascinating stuff, no?

i learned about unisexual mole salamanders which are an all-female complex of salamanders that ‘steal’ sperm from up to five different species of salamanders in the genus Ambystoma and recombine it to produce female hybrid offspring. This method of reproduction is called kleptogenesis (x)

Quagsiren [Water/Ground] A neotenic evolution of wooper, only found in certain regions. They are extremely rare in the wild and were only recently given an official Pokédex listing. They prey primarily on [Water/Grass] types and are known to target Lotads in particular

Based on sirens, in particular the reticulated siren or “Leopard Eel”

Rest In Peace filthy frank

Found some Friendly Men out in the rain

My uncle made me this for Christmas

I caught her resting her head on this rock and she got very mad when I took the picture heheh

I post a lot of peaches because her tank it right by my bed and everyone morning she greets me in her own axolotl way❤

Peaches my little alien. My uncle doesn’t know how to pronounce it so he calls them lilotls and I think that’s a very cute name
