The Lizard Monster SCP-962

SCP-962 appears to have an extra dimensional portion of its body that eats in another world or something. It breathes in liquid and then it like takes in the substances through gills that then distribute the micronutrients around to be converted into energy. How powerful must the acidic enzymes in its digestive system be that allow it to break down anything? And I'm thinking, well maybe the hydrochloric acid is breaking down its external body parts on the outside but it's probably got some kind of acidic shielding inside its stomach and digestive system.
