They are well adapted to life in the water as they are fursome predators.
00:29
And they also have special sensory organs that detect pressure and electrical skeletons.
00:34
Signals.

So it wouldn't really make sense for them to become tetrapods since they don't have a skeleton that is similar to tetrapods.
00:43
And they are pretty happy in the water.
00:47
You know, they are very adapted to being in the water.
00:50
We look at our telios.
00:55
They are a very diverse group of rafean fish.
