Hm... Animalistic or ritualistic ones...

Naga/Nagini are snake-people of Indian culture that you might be able to find some interesting stuff on.

Kelpies are a type of fae, but they're shapeshifters that frequently take the shape of a horse. Common stories have them luring humans into riding them and then drowning them in rivers and lakes, then eating them. They've also taken human form - usually beautiful. It all ends with someone getting eaten, though.

Manticores are these bizarre lion creatures with human faces.

There are a lot of fae creatures that can be considered "animalistic", of course. And a lot of "animalistic" creatures could also be spun into "ritualistic" - all it really takes to make one from the other is an addition of "beliefs" - killing due to tradition or culture rather than desire to kill. That's where you can put your own creativity into the creatures, making them your own.
