Jellyfish

Jellyfish (and all cnidarians) stinging mechanism is the fastest cellular process in nature: cnidae, stinging (or sticking) filaments ejected by cnidocytes (stinging cells) receive an acceleration 40 thousands times bigger than earth gravity acceleration. Some jellyfish of the class Hydrozoa can rejuvenate to an early stadium , avoiding death. Japanese scientist proved that jellyfish contain substances that give benefit to human skin.

No, they are carnivorous. Some species (such as the upside down jellyfish, Cassiopeia xamachana) form a symbiotic relationship with algae (zooxanthellae) and are nourished by sugars derived from algal photosynthesis. But since they also feed on animal organisms, and sugar is neither animal nor vegetable, jellyfish are considered to be strictly carnivorous.

Jellyfish typically defend themselves by stinging with venom-filled tentacles when they feel threatened or accidentally come into contact with something. The stingers on their tentacles release toxins that can cause pain, irritation, and even serious reactions in humans.

Moon jellyfish are carnivores, feeding on small planktonic organisms such as fish eggs, larvae, and copepods. They use their tentacles to capture their prey and then move it to their mouth for digestion.

Jellyfish may come ashore due to factors like ocean currents, winds, tides, and seasonal changes. Strong winds or currents can push jellyfish toward the shore, causing them to strand. Additionally, changes in water temperature or food availability can also influence jellyfish movements towards the coast.

Its because their skin is so thin on the body and tenticles that the oxygen flows through their body and goes through to its vital organs, carbon dioxide is removed the same way. They breathe with their entire bodies.

Slime molds do not have a fixed body shape and therefore do not exhibit bilateral or radial symmetry. They can change shape and move in an amoeba-like manner, giving them asymmetrical characteristics.

We neuro-scientists call this mental condition the "naggy wife who won't shut her bloody mouth and leave her poor husband alone for a moment's peace" syndrome. It is very common amongst jelly-fish who live in hotels. I really like the way you made your question a tongue twister, though.

Nice.

Approximately 20-50 people die worldwide each year from jellyfish stings. The severity of the sting, the species of jellyfish, and the individual's reaction to the venom can all affect the outcome of the encounter. It is important to seek medical attention immediately if stung by a jellyfish.

The lifespan of a jellyfish varies depending on the species, but most jellyfish live for only a few months to a year. Some species, such as the Turritopsis dohrnii jellyfish, are capable of reverting back to their polyp stage and essentially have the potential to be immortal.

Kingdom: Anamalia Phylum: Chordata Class: Chondrichthyes Subclass: Elasmobranchii Superorder: Selachimorpha Orders: Carcharhiniformes Heterodontiformes Hexanchiformes Lamniformes Orectolobiformes Pristiophoriformes Squaliformes Squatiniformes Symmoriida Cladoselachiformes Xenacanthida Eugeneodontida Hybodontiformes Species: There are hundereds of different species of sharks around the world.

The scientific name for the orange jellyfish is Cyanea capillata.

There are numerous species of what we call "Jellyfish." There are five classes of jellyfish: Cubozoa, Hydrozoa, Polypodiozoa, Scyphozoa, and Staurozoa. There are 12 Orders within the various Classes, then numerous families and genera resulting in an estimated 1,700 - 2,000 species.

Common Northern Comb Jelly or Bolinopsis infundibulum

Jellyfish are important in scientific research because they provide insights into evolutionary biology, ecology, and neurobiology. Studying jellyfish can also help researchers better understand marine ecosystems and the impacts of climate change. Additionally, jellyfish possess unique biological features, such as their ability to regenerate and adapt to different environmental conditions, making them valuable subjects for scientific study.

Hydra , Obelia e.t.c. belong to Class Hydrozoa because the Characteristics of the animal that has a life cycle that includes a polyp and a medusa , gametes ectodermal .

They also belong to the Phylum Cnidaria witch means that they have stinging cells .

The Portuguese man o' war got its name because its gas-filled bladder or sac resembles a 18th-century Portuguese warship at full sail. This species is not a single organism, but a colonial organism made up of specialized individual polyps working together.

If a cnidarian lost its stinging cells, it would lose its primary defense mechanism against predators and its ability to capture prey. This would make the cnidarian more vulnerable to predation and reduce its efficiency in obtaining food.

The scientific name for the cannonball jellyfish is Stomolophus meleagris.

Jellyfish belong to the phylum Cnidaria, which includes other organisms like corals and sea anemones. Within the phylum Cnidaria, jellyfish are classified into the class Scyphozoa, which includes true jellyfish, and the class Hydrozoa, which includes hydroids and smaller jellyfish species.

They are called nematocytes. They are one of at least three types of cnidocytes, the very definition of the phylum. Nematocytes sting, the other two types of cnidocytes either adhere, or gum up their prey, substrate, or that guy that wears a helmet and does super glue commercials.

Cnidaria is the scientific name.

The stinging cells of cnidarians, called cnidocytes, are located on specialized structures called nematocysts. These nematocysts are found on the tentacles of cnidarians and are used for defense and capturing prey.

The scientific name for Boxer Jellyfish is Stomolophus meleagris.

Jellyfish belong to the Medusozoa subphylum. The classes of jellyfish include cubozoa, hydrozoa, polypodiozoa, scyphozoa, and staurozoa. They are under the kingdom of Animalia and phylum of cnidaria.
