"Abyssal Lagiacrus also live in deep waters and cave and rarely come to the surface"

You already said that...

And then... In the Latest Games, monsters are now more nomadic and some of them now live in some areas that didn't live there before... Look at Tigrex, Zinogre or many other monsters... Could be possible that year after year, Abyssal Lagia have learned to survive in land?
