Cuttlefish with 2 tentacles and 8 arms

Tentacles can refer to the elongated flexible organs that are present in some animals, especially invertebrates, and sometimes to the hairs of the leaves of some insectivorous plants. Usually, they are used for feeding, feeling and grasping. Anatomically, they work like other muscular hydrostats.

Tentacles in marine animals

The phylum mollusca includes many species with muscular hydrostats in the form of tentacles and arms (octopuses do not have tentacles: they have arms). Tentacles are longer than arms and usually have suckers at their tips only. Squid and cuttlefish have eight arms like octopuses, and also two tentacles, which is one good way to distinguish squid from octopuses.

The tentacles of the Giant Squid and Colossal Squid are particularly formidable, having powerful suckers and deadly teeth at the ends of the tentacle. The teeth of the Giant Squid are small, "bottle-cap" shaped circular saws, while the tentacles of the Colossal Squid wield two long rows of thick, sharp, finger-length screws of protruding bone.

Cnidarians, which include among others the jellyfishes, are another phylum with many tentaculated specimens. Cnidarians often have huge numbers of cnidocytes on their tentacles. Cnidocytes are cells containing a coiled thread-like structure called nematocyst, which can be fired at potential prey. Classes Anthozoa - Corals and sea anemones Cubozoa - Sea wasps or box jellyfish Hydrozoa - Hydroids, hydra-like animals Scyphozoa - Jellyfish Cnidaria is a phylum containing some 10,000 species of relatively simple animals found exclusively in aquatic environments (most species are marine). ...

Many species of the jellyfishlike ctenophores have two tentacles, while some have none. Their tentacles have adhesive structures called colloblasts or lasso cells. These cells burst open when prey comes in contact with the tentacle; sticky threads released from each of the colloblasts will then capture the food. This article or section is in need of attention from an expert on the subject. ... Colloblasts are a cell type of ctenophores. ...

Leaf and tentacle movement on Drosera capensis

In carnivorous plants, tentacles refer to the stalked glands of the upper surface of the leaves. On a sundew plant, they are hairlike projections with a drop of nectar-like glue which attract insects. When an insect is captured, the tentacles bend inward and the leaf rolls together as shown in the picture. The tentacles then secrete digestive enzymes to dissolve and engulf the insect.

Tentacles in cultural context

The great differences between humans and the tentacle-bearing mollusca have led to tentacles being associated with inhumanity and disgust in legend and fiction. For examples, see:

• Tentacle rape
• Purple Tentacle (see Day of the Tentacle)
• Cthulhu
• The Kraken
• Cecaelia
• Ing
