Different Sized Enemies?

This is something I just noticed... The higher level the enemy, the larger he is. For example, this picture shows that a lv 38 molusk is very short compared to a lv 45... Weird!
it just spawnd weird it happens alot on test crabs will either get so small u cant hit them ( literately ) or they will get so big you can only hit them with ranged attacks
No, they are at the exact elevation, the lv 38 isn't standing on the gold. Even if I get close, the higher level appears taller than the lower level.
