These guys are a must-have in Aberration; they are always awake (at least in the bioluminescent area), and thus always have their night buff. Of course, this also means you must always be wary of wild ones while in their territory.

They are at night really good and have a buff but on Day they have to sleep. When u ride them on Day they will lose stamina and torpor is growing fast.

Extremely good for night raiding, if of course you manage to find one AND tame it

When out at night, be sure to take this with a raft or quetzal with platform, so when it is tired, you can get it back to base without it being attacked. Just a tip to ensure that your prized Megalosaurus doesn't die whilst you are out.

These guys can hold things such a parasaurs and argentavis in their mouth without damaging them. This is great for bringing smaller creatures to a safe taming location.
