Its "opening". Mine look like that,Its normal

the slit in it is normal???

 

[reefmate75]

that looks like the same toad i have if its a split that just means its getting bigger, they will split alittle nothing to worry about, when you see brown stuff on it, part of it is dieing, most the time thats a easy fix, just blow it off with a power head or your hand stiring up the water

Leathers can be senitive.... It's split can be it's enlarging or just it is acclimating to it's environment.
