It was recently discovered that New York City was home to an undescribed leopard frog species [actually, a pickerel frog], which had actually been noticed first about a century ago. It has now been described as Rana kauffeldi [although it is a Lithobates] in an open-access paper:

Jeremy A. Feinberg, Catherine E. Newman, Gregory J. Watkins-Colwell, Matthew D. Schlesinger, Brian Zarate, Brian R. Curry, H. Bradley Shaffer, Joanna Burger, 2014. Cryptic Diversity in Metropolis: Confirmation of a New Leopard Frog Species (Anura: Ranidae) from New York City and Surrounding Atlantic Coast Regions. [FONT=Times New Roman, serif]PLoS ONE 9(10): e108213. doi:10.1371/journal.pone.0108213[/FONT]


[FONT=Times New Roman, serif]Abstract[/FONT]


[FONT=Times New Roman, serif]We describe a new cryptic species of leopard frog from the New York City metropolitan area and surrounding coastal regions. This species is morphologically similar to two largely parapatric eastern congeners, [/FONT][FONT=Times New Roman, serif]Rana sphenocephala[/FONT][FONT=Times New Roman, serif] and [/FONT][FONT=Times New Roman, serif]R. pipiens[/FONT][FONT=Times New Roman, serif]. We primarily use bioacoustic and molecular data to characterize the new species, but also examine other lines of evidence. This discovery is unexpected in one of the largest and most densely populated urban parts of the world. It also demonstrates that new vertebrate species can still be found periodically even in well-studied locales rarely associated with undocumented biodiversity. The new species typically occurs in expansive open-canopied wetlands interspersed with upland patches, but centuries of loss and impact to these habitats give some cause for conservation concern. Other concerns include regional extirpations, fragmented extant populations, and a restricted overall geographic distribution. We assign a type locality within New York City and report a narrow and largely coastal lowland distribution from central Connecticut to northern New Jersey (based on genetic data) and south to North Carolina (based on call data).[/FONT]

I saw this a while ago. It's very interesting. I'm just waiting for a paper coming out in a few years rejecting the hypothesis that these are actually a new species. lol

    Hi Nerdybirds - open a thread, that usually gets more views and also allows you to post pictures and give more background information: water parameters, age, etc.

    Yeah his gills is kinda small and it can be caused by nitrate level, I am taking care of it atm, I am worried about his weight, is he only overfed or are there any kinds of problems there ?

  • MVM1991:
    Well, again, I'm no expert. But I did just read axolotls are supposed to have a body about as wide as their head. The gills I'd say are the biggest problem, which could reduce oxygen intake, which could make a whole mess of problems.

    Hello, I am a new owner of a 3 month old axolotl, and although I have done a lot of research on axolotls, I can barely find any for babies. If anyone can help me with these questions, I would be super happy. How many hours do baby axolotls tend to sleep per day? How many times should I feed it and what would be considered too much (it's current diet is freeze-dried brine shrimp and blood worms, and I currently feed it around 3 bloodworms since they are not that big)? How many times a week should I change the water and how? I have a good filter and use Prime as my conditioner to remove the chlorine and other chemicals, but I still need to figure out how to deal with ammonia and such in the water. How do I clean it's waste (should I use a dropper to easily pick it up)? I need a better cooling system because currently I use ice packs on the side of the tank and I make sure to angle my ac so that it hits the tank.

    I also leave the lid open during the day so that evaporation can cool down my tank. I want to buy a fan, but since winter is coming I won't have to buy one yet. Lastly, what water testers are effective and affordable for a broke student like myself? Please, if anyone has any advice I will love to hear it. I care for this creature too much at this point, but I have no one to help me with caring for it other than the internet :,)

    Hi LauraLobster I am a new owner of axolotls myself and have been getting advice from things like this, I feed mine twice a day on blackworms and brine shrimp blood worms are more of a treat food, a question on where you are keeping you axolotl are you keeping it in the main tank or in a tub also if in the tank did you cycle it first? and if not i suggest tubing it until the tank it cycled, mine are still tubed since I was given bad advice by the shop people about cycling my tank and am still in the process of cycling it. I use pipettes to clean up the mess of my axolotls. I use the API mater test kit for freshwater tanks I am also a student and had to look around to find it the cheapest I could.

    Hi LauraLobster, like you I got my first ever Axolotl back in July. Iv found that he has enjoyed and eaten red wigglers well. They are a good source of protein and help provide the nutrients a young lotl needs to grow up big and strong. You will probably need to break it up into smaller pieces until they get bigger but they are what I have primarily fed my buddy since I got him. He’s actually so picky that he won’t even eat his pellets anymore and will hold out till he gets his favorite wormy.
