This article will explain the different ways that these polyps live. It will also discuss Gastrocysts, Nematocysts, and Tentacles. Hopefully, this will help you identify the most common types of these polyps, and how they are spread. Whether they are found in the mouth, on the skin, or in the gastrovascular system, they all have the same basic life cycle.

Anal fissures

Hemorrhoids are intrinsically part of human anatomy. They protect the internal structures of the anal canal. Hemorrhoids can be internal or external, and both can cause swelling and pain. They also tend to enlarge with external pressure. The anal fissure is where the polyp takes in food and expels waste. Hemorrhoids usually occur at or near the anal opening, but they can also develop in the anal canal itself.

Gastrocysts

The digestive system is responsible for breaking down the food we eat into energy and expending the non-nutritive components. Polyps of the rectum and colon are typically harmless but can be cancerous. While most polyps of the colon are benign, others can develop into adenomas, which are cancerous growths originating in the glandular tissue.

Nematocysts

They are planktonic marine predators with transparent bodies and tentacles. They typically use defensive behaviors to capture prey and may be considered undesirable prey due to low nutritional value. Several animal lineages sequester nematocysts, including Haeckelia rubra, Platyhelminthes, and Mollusca. Despite limited information, this behavior may provide crucial insights into the mechanisms by which nematocysts take in food and expend waste.

Tentacles

The nervous system of jellyfish is simple yet complex. It coordinates complex movements of tentacles and a nerve ring across the body. This nerve ring may be made of fibers that form nerve plexi or nerve cords. In motile medusa, the nervous system is more complex than in sessile polyps. A nerve ring around the bell controls the movements of the tentacles. Cnidarian nerve cells exhibit mixed characteristics of sensory and motor neurons.

Coenosarc

Coenosarcs are a polyp’s primary function: to take in food, digest it and expel it. They form a tube-like structure with an opening at the top of the body, called the coenosarc. In polyps, this opening is the mouth, and in medusae, the mouth is surrounded by tentacles and lies at the distal end of the main body structure. Inside the manubrium, gonads are located. Food is distributed throughout the canal system, which consists of four radial canals and an outer ring.

Ecology

The corals have a mutualistic relationship with algae that fuels reef building. They produce microscopic bands in their corallites due to the daily surges in photosynthetic growth. Fossil corals from the Triassic Period in Turkey show microscopic daily banding and other indications of a mutualistic relationship. These corals have been in a mutualistic relationship for at least 200 million years. Coral polyps take in algae, and algae provide 90 percent of the coral’s food.

Treatment

Polyps on the colon are harmless clumps of tissue. They are not cancerous and can vary from the size of a pea to a golf ball. However, if the polyp is not removed, it can turn cancerous. Diverticulosis, another condition characterized by polyps on the colon, can be a sign of colon cancer. The polyp can also be the cause of rectal bleeding.
