The tentacles are almost cylindrical and have bands of cilia which create a water current towards the mouth. The animal extracts edible material from the flow of water.
This article introduces 20 animals with tentacles, including both venomous and non-venomous species, explaining the functions of tentacles and providing examples across various animal groups—not only aquatic species, where tentacles are most commonly recognized.
A narrow, flexible, unjointed part extending from the body of certain animals, such as an octopus, jellyfish, or sea anemone. Tentacles are used for feeling, grasping, or moving.
Other marine animals, including octopuses and squid, have more developed tentacles that aid in hunting and navigating their environments. Additionally, some terrestrial animals like the star-nosed mole and caecilians utilize tentacles for sensory purposes, enhancing their ability to locate food.
These tentacles are grouped into eight clusters, each containing 70–150 tentacles. They are equipped with stinging cells that help capture prey, showcasing the jellyfish’s adaptation to its environment.
Tentacles are also a characteristic feature of jellyfish, sea cucumbers, anemones and other cnidarians, and are often armed with stinging cells that immobilise prey.
The tentacles of an animal such as an octopus are the long thin parts that are used for feeling and holding things, for getting food, and for moving.
