Answer:
Nautiluses
Step-by-step explanation:
look them up :)
The nautilus is a pelagic marine mollusc (land inhabitants known as snails are molluscs as well) of the cephalopod family Nautilidae. They inhabit the deep slopes of coral reefs of the Indo-Pacific. These soft-bodied creatures live inside an intricately chambered shell. The "tentacles" of the nautili are actually cirri , composed of long, soft, flexible appendages which are retractable into corresponding hardened sheaths. Nautiluses reproduce by laying eggs. They have a seemingly simple brain, not the large complex brains of octopus, cuttlefish and squid, and had long been assumed to lack intelligence. Nautiluses are scavengers and opportunistic predators. The cephalopod nautilus has a single heart that pumps blood.
