tentacu-, tentac-

(Late Latin: feeler, to feel; a flexible appendage serving as an organ for moving around or for touching)

bitentacle (s) (adjective) (not comparable)
Descriptive of any creature that has two long, thin, armlike parts: While researching zoological species in the sea, Brian noticed that there were some bitentacle animals in addition to the octopi (eight-tentacle animals) and squids (ten-tentacle animals).

One example of a bitentacle is the cuttlefish that has eight arms and two tentacles that have toothless suckers with which they grab and hold their prey.

bitentaculate (verb), bitentaculates; bitentaculated; bitentaculating
Using two elongated, flexible, unsegmented extensions, or organs, like those surrounding the mouth or oral cavity of the squid in order to feel, to hold on to something, or to move from place to place: Some sea creatures bitentaculate in tidal pools and are carefully studied by oceanographers.
cnidarian tentacle (s) (nigh DAR ee uhn) (noun), cnidarian tentacles (pl)
1. Corals, jellyfish, sea anemones, and hydras (several small freshwater animals), having naked cylindrical bodies and oral openings surrounded by armlike parts: Cnidarian tentacles consist of rings of elongated and flexible extensions which are used to capture food and to defend themselves against predators.

Cells in the cnidarian tentacles and in the outer body surfaces are armed with stinging, harpoon-like structures called "nematocysts" which contain toxins that can cause their victims to have paralysis.

2. Etymology: from Greek cnidaria, "nettle" and refers to the stinging structures that are characteristic of these animals.

multitentacular (adjective), more multitentacular, most multitentacular
Characteristic of having numerous elongated and flexible organs that occur on the head or near the mouth which are used for feeding, feeling, holding on to something, or locomotion (movement); such as, the octopus, squid, and the jellyfish: The multitentacular creature that most people are aware of is the octopus which has a bilaterally symmetrical body with a head and a pair of eyes on each side and tentacles that are arranged around its mouth for consuming food.

When an octopus moves in the water from one place to another, it is the rear part of the body that goes first as its multitentacular body parts are used to propel it around.

octotentacle (s) (noun), octotentacles (pl)
A creature with eight tentacles: The animated humanoid below demonstrates what an octotentacle is, as shown by her upper tentacles, which can be used as arms, and the lower four tentacles that function as feet.

Actually, octotentacle is a more accurate term than octopus, which means "eight feet", because it is obvious that octopi really do not have any feet; however, they do have eight tentacles.

pinnitentacular (adjective), more pinnitentacular, most pinnitentacular
Referring to the feathery finger-like extensions surrounding the mouths of some underwater animals: A polyp is a pinnitentacular creature in the ocean that has a body like a tube and a ring of tentacles around its mouth; or a coral, having a cylindrical body and oral openings which are usually surrounded by pinnitentacular structures.
quadritentacles (pl) (noun) (no singular)
Four flexible armlike parts that are used for feeling and moving around.
tentacle (s) (noun), tentacles (pl)
1. Long, thin, armlike parts of some sea animals which are used for feeling and holding things, catching food, or moving around; such as, a squid, the octopus, and the jellyfish: An octopus has eight tentacles which are used for many purposes.

Bigfin squids have huge wing-like fins extending from their mantle and very long, slender tentacles sticking stiffly out from their bodies, then bending at right angles and trailing downwards; which suggest that the bigfin waits for prey to blunder into them; and, although their bodies are less than half a meter long, the tentacles extend seven meters or more.

One of several deep-sea species that can swim using the elephant-ear-like fins on their heads, earning them the nickname "Dumbo" octopuses, have tentacles that are also connected by membranes, forming a bell and it has suckers that can be turned into bioluminescent organs that emit a blue-green light, possibly to lure prey.

2. An elongated flexible unsegmented extension, as one of those surrounding the mouth or oral cavity of the squid, used for feeling, grasping, or moving around: Like octopi, squids also use their tentacles to help them move, feed, or hold onto things.
3. One of the sensitive glandular hairs or filaments on the leaves of insectivorous (insect-eating) plants, such as the sundew whose secretions trap and digest prey: Irwin noticed that if anything touches the tentacles on the leaves of the sundew plant, the leaves automatically close up, as if trying to capture whatever might be coming into contact with them.
4. A part or extension; especially, with respect to the ability to grasp, to influence, or to control: There was an espionage network with far-reaching tentacles.

Henry's cousin was caught in the tentacles of organized crime.

The neighborhood has been caught in the tentacles of narcotics.

tentacle (adjective), more tentacle, most tentacle
Relating to a structure that entraps food and mucus that may be employed by certain sea organisms to facilitate the capture of particles: Sea cucumbers, nuculoid bivalve mollusks, and some tube-dwelling polychaetes (marine worms) gather detritus (loose fragments of organic waste) by means of tentacle structures at the sediment-water area and transport them to their mouths.

Some tentacle feeders are anemones and corals that use various types of stinging, entrapping, and mucus-laden nematocysts, or specialized cells, that contain a barbed and threadlike tube that delivers paralyzing stings when they are sent into attackers or prey.

tentacled (adjective), more tentacled, most tentacled
Provided with or having elongated flexible organs used for feeding, grasping, moving, etc.: Many creatures that live in the tidal pools are tentacled animals.
tentacled snake (s) (noun), tentacled snakes (pl)
An unusual reptile that lives in water: The tentacled snake is distinguished from its relatives by a unique pair of soft, fleshy tentacles on its nose.

Tentacled snakes are sluggish and nocturnal, and they hunt by lying in weed-choked water, waiting for prey to swim by.

A female tentacled snake gives birth to 5-13 live young ones underwater.

tentacular (adjective), more tentacular, most tentacular
Pertaining to or of the nature of an elongated and flexibly unsegmented extension that is used for grasping, moving around, touching and feeling, etc.: The biologists were studying the tidal pool animals to determine which ones were the most tentacular.
tentacular canal (s) (noun), tentacular canals (pl)
A passage that extends into an elongated, flexible, and unsegmented protrusion: Some invertebrates have tentacular canals in their tentacles; such as, Hydrozoa or jelly-fish.

To use the organic projections, or appendages, that are equipped with sensory receptors and which are used for holding things; such as, food and for moving around: There are some sea creatures that tentaculate with the projections around their mouths in order to obtain food.
tentaculated (adjective), more tentaculated, most tentaculated
Descriptive of extended and flexible growths; usually, occurring on the head or around the mouth of an animal which is used to touch or to hold something, or to change locations: There is no doubt that many tentaculated animals in oceans and seas still have not been identified by scientists.
