Discussion Overview

The discussion centers on whether tadpoles require specific elements, particularly iodine, in their water to successfully undergo metamorphosis into frogs. Participants explore the factors influencing this process, including nutrition, species variation, and environmental conditions.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant recalls that their tadpoles did not metamorphose and questions if a specific mineral in the water is necessary for this process.
  • Another participant suggests that while proper nutrition is essential for growth, they do not believe any special elements in the water are required for metamorphosis.
  • Timing for metamorphosis is noted to be species-dependent, with some tadpoles taking only a month or two, while others may take up to a year.
  • Water temperature is mentioned as a factor that can affect the rate of metamorphosis, with cooler temperatures potentially slowing the process.
  • A later reply identifies the tadpoles as likely being bullfrog tadpoles, which are known to take over a year to metamorphose.
  • Another participant references a video claiming that iodine is necessary for tadpoles to develop into frogs, though they acknowledge the lack of corroborating sources.

Areas of Agreement / Disagreement

Participants express differing views on the necessity of specific elements in the water for tadpole metamorphosis. While some argue that nutrition is sufficient, others introduce the idea of iodine as a potential requirement, leaving the discussion unresolved.

Contextual Notes

There is uncertainty regarding the specific requirements for tadpole metamorphosis, including the role of iodine and other environmental factors. The discussion reflects varying experiences and interpretations of available information.

I used to have a bunch of tadpoles and they never turned into frogs. Long after I got rid of them, I read up about how tadpoles need a certain kind of mineral or something in the water (forgot what it was) or else they won't turn into frogs.
Recently I tried to read up on it some more and I couldn't find ANYTHING on the internet that talks about that.

So do tadpoles really need this element in their water, whatever it was, or am I crazy?

They would obviously need proper nutrition to grow sufficiently to undergo metamorphosis, but I don't think that would include anything special in the water.

How long did you wait for your tadpoles to undergo metamorphosis? The timing is species dependent. Some will only take a month or two from hatching to metamorphosis, and others can take a full year. Water temperature can also affect the rate of metamorphosis, with cooler temperatures slowing the process.

I have no way to know if you're crazy though. :wink: With all the odd things around on the internet, who knows, maybe you did read something...doesn't mean it was right.

Yeah I fed them and the water was probably a little cold, but I live in Florida so it couldn't have been too bad.
I had them in there a while. My uncle gave them to me. I wanted them because they were so big. They were the biggest tadpoles I'd ever seen.
I put them in a big container and left them outside with a covering over it partly and fed them stuff.
Since they were big when I got them, I assumed they were close to metamorphosis. Maybe I was wrong. I had them for maybe a little less than a year.

And assuming everything you read on the internet is correct, then I'd have to be crazy if it turned out not to be true.

Yep, sounds like you had bullfrog tadpoles. They can take over a year to undergo metamorphosis and would be BIG.

Here's a video where the guy explains that tadpoles need iodine to develop into frogs. I heard this somewhere else, but I couldn't find any other sources.
He says it starting at about 3:00 into the video.
So apparently it's iodine.
