Sea nettle

The Sea Nettle is a species of jellyfish occurring particularly in Atlantic ocean. The term "sea nettle" is also used for a related species, Chrysaora fuscescens. Which is on the west coast of North America from California to Alaska where usually it spends most of it times, that it live and reproduces. The Atlantic sea nettle is a bell-shaped invertebrate, usually semi-transparent and with small, white dots and reddish-brown stripes, The sting of the Sea Nettle is a sting related to the moderate" to "severe" and can be pernicious to smaller prey. It cannot make a death to a human but it could inflict sting that could paralyze a small body part. The sea nettle is symmetrical, and carnivorous. Its mouth is located at the center of one end of the body, which opens to a gastrovascular cavity that is used for digestion. It has tentacles that surround the mouth to capture food. Nettles have no excretory or respiratory organs. Each sea nettle is free-swimming and can reproduce both sexually and asexually

Anatomy
This jellyfish, the Sea nettle is saucer-shaped with brown or red pigments, usually 6-8 inches in diameter. Four oral arms and long marginal tentacles that hang from the bell and can be several feet. Symptoms from sea nettle stings are similar to those of the lion’s mane. There are more of them during the summer, when people are likely to be swimming in the ocean, this species is thought to be responsible for most of the jellyfish stings that occur in South Carolina. Exercise caution if sea nettles are observed in the water The Sea nettle also has a swimming bell that can reach 10 inches (25 centimeters) in diameter, but most sea nettles are much smaller. .htmlThe edges of the swimming bell are petal shaped. One of the very large tentacle emerges from between the stinging tentacles, and twice as many small tentacles arise from beneath the petals. The narrow oral arms are long and filmy. The colors of medusae range from milky white to white with radiating purplish red stripes on the bell. Which has a very fine color to the Jellyfish that makes it look really cool Jellyfish and the sea nettle have 3 main body parts 1) the Bell The part of their body that looks like a big umbrella. Under the jellyfish's body 2) The Tentacles which look like big strings, and they cause the sting when ever you touch them. Some people think that jellyfish have teeth that bite you when you get stung, But really it's there Tentacles, 3) Oral Arms these are the parts that help the Sea Nettle eat the food that they collect. When they are done eating

Reproduction
The reproduction occurs sexually like any other jellyfish. The life cycle of sea nettles has both a polyp and a medusa stage. The Sea Nettle are either male or female, and release egg and sperm into the water during the summer. Larva attach themselves to a hard surface and grow into miniature polyps. The polyps live on the bottom and survive the winter in a dormant state. During May through August, the polyps bud off tiny sea nettles about 1/25 of an inch in diameter this turns into the growth of a jellyfish. 

Ecology
The Sea Nettle is mostly abundant during the summer along the east coast of the United states. From New England from The USA, The Sea Nettle is mostly in Chesapeake Bay. sea nettles like water with salt with organic materials totalling only about 0.2k of their entire live weight. For this reason, very little food can provide enough organic materials to result in a lot of growth. the jellyfish can get big very, very rapidly, and the amount of food that is in the bay they grow very fast and have allot of food to grow. Sea nettles are geared for high reproduction. They begin producing eggs when the swimming bell is only about 1 1/2 inches in diameter There are allot of eggs in the bay which hatch many of the sea nettles in the bay. "with a nettle about 4 inches in diameter shedding about 40,000 eggs into the water daily. The polyps produce more polyps. Each polyp produces 45 jellyfish each summer The Sea Nettle is in its ability to live in water of low salinity. Most jellyfish species live at ocean water, about 35 ppt. The Sea Nettle prefers waters having as little as salt, and may have estuaries like Chesapeake Bay" 

Eating
Sea Nettles are carnivores, The Sea Nettle feeds on the zooplankton, ctenophores, and other jellyfish. They sting their prey with its tentacles the it is transported to the gastrovascular cavity where it is subsequently digested. The Sea Nettle usually eats plankton which is microscopic plants and animals drifting in water. They also eat small crustaceans, comb jellies, and fish eggs and larvae. Nettles also eat young minnows, bay anchovy eggs, worms, and mosquito larvae. sea Nettles capture there prey and contact there tentacles with the prey underneath their bell to trap the prey These tentacles have millions of microscopic stinging cells that inject toxins to stun or kill tiny animals, and which are responsible for the stings swimmers feel Then the Sea Nettle transports it to the main tentacles to the heart-shaped gastric pouches which are in the swimming bell. Where the digestion occurs. All the jellyfish are prodigious predators because they swim and feed continuously. They do not have eyes, so they dont need light to find prey. They mostly feed without interruption because most of the many tentacles function independently of the others. But the Tentacles provided a very, very large area for eating. The thing it mostly eats is microscopic crustaceans, usually copepods that are very abundant in Bay waters. They also eat young minnows bay anchovy eggs, worms, mosquito larvae, and comb jellies, so they would seldom go without something to eat.
