Raising Tadpoles

On the afternoon of June 15th, my husband and two-year-old had a surprise for my five-year-old and me.  We had spent the morning apart.  My five-year-old was in a camp, I had a couple hours to myself (yay), and my husband took the two-year-old to a park.

Guess what they found at the park?  You guessed it – hundreds of tiny black tadpoles in a pool of water by a stream.  My husband said that by scooping a cup in the water, he easily got three of the tadpoles.  He also said the two-year-old carefully and proudly carried his cup to the car.

The five-year-old was delighted too, and together the “boys” set about to create a small habitat for the tadpoles. I gave them an old storage container, and my husband found some rocks in the garden.  He used the same water conditioner that we use for our fish aquarium, which takes chlorine out of the water.

That night they took a trip to the pet store and bought an inexpensive filter (less than $15), although we ended up not using the filter and instead let it just circulate the water in the container. This provided oxygen. They also found some frog/tadpole food at the pet store.

We fed the tadpoles the frog food, but we also added some frozen spinach because my husband read online that they like that.  They ate it up!  The boys also visited the stream again and brought home water from it.  We were told that there might be tiny microorganisms that the tadpoles would feed on in that water.

We kept the container on our porch and covered it with some old window screen to keep the mosquitoes out, and over the next two and a half weeks, we watched them grow.  It was exciting for the whole family.  Every morning my two boys got up and went out to check the tadpoles, and they also checked on them in the evenings.

Let me pause here and commend my husband for taking care of the tadpoles and the habitat during this entire project!

Part of the fun was trying to figure out what kind of frogs they were, yet as they grew so quickly, we noticed that they looked very similar to the Fowler toads who inhabit our yard.  In the end, we realized that’s exactly what they were.

Fowler toads breed in this area in May and June, and my herpetologist friend told me that if the tadpoles were very black when they were tiny, then they were definitely toads.  Tree or chorus frog tadpoles are clear, and if viewed from the bottom, you can see an orange-colored circle, which are their intestines.

This made sense because as I mentioned we had recently found baby Fowler toads in our yard, and on our trip to Watson’s Mill Bridge State Park last month, we saw hundreds, if not thousands of tiny black tadpoles in the shallow water near that bridge.

In regards to Fowler toads, the Savannah River Ecology Laboratory’s (SREL) website states: “Females lay eggs in strings with clutches of up to 25,000 eggs in spring or summer after a heavy rain.  Tadpoles go through metamorphosis within 2 months. Sexual maturity is reached in 1-3 years, differing among sex and locality.”

On July 4th – a very fitting day – we released two baby toads and one toadlet back into the wild where we found them.  Since two of them had already lost their tails – literally within one day! – and they were sitting up on the rocks, we feared their diet had changed, and we wouldn’t be able to provide them with the tiny bugs they needed to eat.  The toads were so small they could fit on my fingertip.

One of the tadpoles was always smaller and developed a day or two behind the others.  This one, which was a “toadlet” with four legs, but it was still in the water and had a tail, we placed in a shallow part of the water with leaf cover so it could hide.  I’m sure within a day, it would be hopping into the forest with the other toads.

Most tadpoles and baby frogs become food for larger animals, but we were happy to at least give three little guys a head start.  The pool where we took them from was drying up and in the full sun when we returned to it.  A few surviving tadpoles in it were not as well developed as ours.

For me, it was a wonderful experience – something I had never done before – but watching the delight on my boy’s faces is something I’ll never forget.  And who knows?  Maybe this will become a yearly ritual that will foster even more good memories.

Below is a slideshow of all the photos I took during this fun project so that you can see the metamorphosis.  I’ve put dates on the photos for your reference.

Tadpole Update #3: We have Froglets!!

It’s been an exciting morning for us in the Pabis household!  We just checked on our tadpoles, and two of them have FRONT AND BACK legs!!  This happened overnight because we looked at them yesterday.  Two days ago I also took photos, and they had back legs then too.  You can see those photos and the ones I took this morning below.  I have put the dates on the photos for your reference.

We are still not completely sure what they are.  They look so much like the fowler toads in our yard, but I think the toad’s cycle would be shorter.  My guess is a Southern Chorus Frog.  I’m going to send this to a couple of experts, and I’ll get back to you on that! (Update: After looking at some more photos in a book and online, we’re thinking they are fowler toads.)

Tadpole Update #2: They have legs!

We were very excited this evening to see tiny legs on our tadpoles!  Below are some photos that I took in the last few days.  I’ve put dates on the images so that you can see the progress.  Though we thought they were about to get legs, tonight was the first time we could definitely see them.  To see my first photos of the tadpoles and learn how we got them and how we’re taking care of them, click here.

Have you ever raised tadpoles or any other kind of critter?

Guess who’s raising tadpoles?

Last week (on June 15th) when my five-year-old and I returned from his mini-camp, my husband and two-year-old surprised us with tadpoles!  They collected them at a stream where they found hundreds of tadpoles.  Most of them will get eaten by predators, so we’re going to help three of them along until they mature and then release them in the same spot we found them.  (At least we hope we get that far.)  So far they are doing well!

We’re keeping them in a container box on the porch. We used tap water, but we put a water conditioner in it that we use for our fish aquarium. Later we also added some of the water and algae from the stream that the tadpoles came from. We put some rocks and a filter in the water, and we are feeding them bits of frozen spinach and tapole/frog food we found at the pet store. They have gotten considerably fatter since we got them, and they seem happy!

We keep a screen over the box when we’re not watching them to keep mosquitoes and other pests out of the box.

I’ll keep you updated on the progress.

And let’s have a round of applause for my husband who initiated and did the work for this awesome homeschool science project!
