Iaculis comes from the latin Iaculator- meaning a spear or lance thrower.
Old creature concept I had brewing that went through several iterations. Inspired by jousting knights in armour. This alien predator literally hunts by running its prey through with its bony acid seeping proboscis. It then strips the meat from its lance like a shish kebab, stuffing the flesh into its drawstring hole of a mouth. Anything that remains is liquefied and slurped away.
