|When can we find gill slits on tadpoles?|
|Question Date: 2014-10-08|
Tadpoles are actually born with gills and after
a few days a flap of skin covers them. You should
still be able to see them if you look close enough
though they will be very small.
Tadpoles need to breathe air just like us, but
use gills instead of lungs. So there should be
gill slits on a tadpole as long as it isn’t close
to turning into a frog as which point it develops
lungs, just like us.
The gills are on the side of the throat, behind
One step in a frog's life cycle is when the egg
hatches and a tadpole comes out. This can happen
anywhere between 6-21 days after fertilization.
After about 4 weeks the tadpoles begin to grow
gills, and then soon after the gills disappear.
Tadpoles need gills because they are in the water,
but adult frogs do not need them because adult
frogs land animals.
Frogs develop from tadpoles slowly, over the
course of several months or up to a year. The
tadpoles have gills for different amounts of time
depending on exactly what type of frog they will
become. They will have gills once they hatch from
eggs, and these gills will start to close up after
1-2 months. You'll notice that around that time,
the tadpole starts to breathe by swimming to the
