ink gland, an organ of most cephalopods (for example, octopuses, cuttlefish, squids), in which a liquid containing grains of black pigment from the melanin group is formed. Performs a protective function. It consists of a glandular part and a reservoir connected by a duct to the rectum. Old cells of the glandular part of the breast are gradually destroyed and, dissolving in the secretions of the gland, accumulate in the reservoir. When in danger, the mollusk throws the contents of the tank out, and a dark cloud forms in the water, creating a “smoke screen” that hides the mollusk. The coloring power of the ink liquid is unusually high, for example cuttlefish in 5 sec colors water in a tank with a capacity of up to 5.5 thousand. l. From the dried contents of Ch. m., treated with caustic potassium, paint was obtained - natural sepia.

what is an ink sac, mollusc jet propulsion and got the best answer
Answer from Elena Kazakova[guru]
The ink sac, or ink gland, is an unpaired protective organ characteristic of most cephalopods (Cephalopoda). It is an outgrowth of the rectum.
Structure and principle of operation
The ink sac consists of a folded glandular part and a reservoir connected by a duct to the rectum. In the cells of the glandular part, a pigment is formed from the group of melanins of black, dark brown or blue colors, which enters the reservoir with the death of these cells (holocrine secretion).
When in danger, the mollusk contracts the muscles of the tank wall, squeezing the contents through the duct into the rectum and then through the anus and funnel. The pigment, dissolving in water in the form of a cloud, disorients the attacking predator. At this time, the mollusk turns pale and sharply changes the trajectory of its movement. The inky liquid irritates the eyes of the predator and leads to temporary anesthesia of the olfactory organs, which gives the mollusk the opportunity to hide.
Application value
The contents of the ink sacs of cuttlefish and squid were used as the basis for Chinese ink. In Europe, natural sepia paint was produced by treating gland secretions with potassium hydroxide.
Jet propulsion is used by many mollusks - octopuses, squids, cuttlefish, jellyfish. For example, a sea scallop mollusk moves forward due to the reactive force of a stream of water thrown out of the shell during a sharp compression of its valves.
The squid's jet engine is of greatest interest. When moving slowly, the squid uses a large diamond-shaped fin that periodically bends. It uses a jet engine to throw quickly. Muscle tissue - the mantle surrounds the mollusk's body on all sides; the volume of its cavity is almost half the volume of the squid's body. The animal sucks water into the mantle cavity, and then sharply throws out a stream of water through a narrow nozzle. This nozzle is equipped with a special valve, and the muscles can turn it, changing the direction of movement. The squid engine is very economical, it is capable of reaching speeds of up to 60 - 70 km/h. (Some researchers believe that even up to 150 km/h!) No wonder the squid is called a “living torpedo.”
Reply from Alex Prange[guru]
An ink sac and the jet movement of mollusks are two different things. The ink sac of mollusks (octopus, cuttlefish, squid) serves as a smoke screen (in case of an attack on them), and the jet speed is achieved by the fact that they fill the entire free cavity (movement) with water and forcefully push out the water by contracting muscles. This is how this speed is achieved.

Well, it’s like the Second Golf diesel, it starts out of fear from a traffic light, in clouds of soot, just like the octopus, out of fear. Small.

What does "ink bag" mean?
Encyclopedic Dictionary, 1998
ink bag
INK SAC (ink gland) is the organ of most cephalopods that produces black pigment. When in danger, the mollusk throws out the contents of the ink sac, forming a dark cloud in the water that hides it from the enemy. Sepia was obtained from the dried contents of the ink clam.
