Barnacle from Half-Life

An organic creature with almost no intelligence. It is an organic bag that clings to the ceiling. It is three meters high and twice as wide as a human. It has a tongue that is 8 meters long. It always hangs on the ceiling and lowers its long tongue to catch prey. It does not distinguish between edible prey and something that can kill it. It has 8 teeth that look like thin fangs, but as a rule, barnacles do not use them at all for chewing, but use them only to make it easier for it to swallow prey. The barnacle's powerful stomach allows it to cope with a living person in just half an hour, and during this time, only bones remain from the person. When the barnacle has finished digesting its prey, it releases the remaining bones back through its mouth. Since the barnacle is always hanging from the ceiling, its tongue is based in its stomach. Inside the barnacle's stomach are several thin, fleshy tiny heads, like faucets, that release digestive juices.
