The texture quality of the shell on that tortoise is incredible those are high settings o.o.
About ported mobs there are several from FFXI :
copy pasted: Imps,mandragoras,rafflesia,raptor,skeletons,ogres etc.
but there are more copy pasted names with different looks: treant,puk,deremite,bogy,sheep,buffalo,gnat,ladybug,bees,chigoe,arhima,cactuar,crabs,efts, etc.
really the only original mob i have seen in FFXIV is antelope
