As much as you want to save the babies, this is a normal part of living in the wild for frog, and for snek. Human should not interfere in environment. Human should intervene when damage is caused by humans directly or indirectly, but if this snake is supposed to live here and you taking these froggo away you may upset a balance of this ecosystem. Protect frog from feral animal, from pets, from introduced species, from danger in environment like poison, pollution, landfill. From cars and machines. Not from native predators. if you take all the prey away, you save the frog but maybe you make this snek starve. Let nature exist as it always has. Step in when danger is not natural or you find an injured friend. important: it also very dangerous to interfere with a venomous snake. Cecil is trained to handle and relocate these danger noodle friend but you must have TRAINING. Snek friend only have this mouth, no hands for punching or voice for screaming. He do not want to bite you but a human is a scary thing and you won’t know if he there a lot of the time. Especially in marshy area. Not worth a risk of step on him or grab him by accident. Definitely do not touch or move him ever if you see him.
pls stay safe friend. I know it sad to see animal friends being preyed on, but if they both belong there then they should pls be left to do what they do. trust that frog and snek have been living together for thousands of years and one noodle will not kill all the froggos.
