The term 'Tentacled Sea Creature' refers to a variety of aquatic animals that have tentacles, such as anemones, octopuses, squids, and JELLYFISH. Anemones are soft-bodied invertebrates that live in the ocean and have tentacles with stinging cells. Octopuses are cephalopods with eight arms and two longer tentacles. Squids are also cephalopods with eight arms and two longer tentacles, but they have a distinct internal shell. JELLYFISH are gelatinous creatures with tentacles that contain stinging cells. All of these creatures are found in the ocean and have tentacles, making them tentacled sea creatures.
