Jellyfish

The lions mane jellyfish was first discovered in 1870 when there was one found washed up on the shore at Massachusetts Bay.

It depends on the place of struck..........

Jellyfish are interesting animals. There are many facts that could be used in an introductory paragraph, for example, the many different species, and the fact they do not have a brain and still live.

Sharks are not bony fish. They are cartilaginous fish.

3 characteristics of cnidarians are having tentacles, cnidocytes, and digestion. Cnidara have poisonous stinging cells and soft bodies. Stinging cells can be found in the tentacles of a jellyfish.

Contractions pump blood through the aorta to the head.

It depends on the species of jellyfish. The irukandji jellyfish has the potential to kill a person in 2 minutes.

No one invented it. Are you attempting to suggest that the species was man-made?

no

Yes, Jellyfish Have Twenty Five Eyes! == == == ==

We've been doing a 10 month house swap here since August and it is now April - and just today, my wife saw a kid get stung by a jellyfish on Keawakapu beach. We've never seen or heard of any other jellyfish incidents since we've been here. Looking online I saw a warning for jellyfish coming ashore in Oahu in May - so maybe the season is April - May? There really is no particular "season" for jelly fish. Jelly fish usually will come into shore, primarily on the leeward side of the islands, about 7-10 days following a full moon. Tradewinds have also been known to blow jellyfish in closer to shore. Best course of action is to be aware of the posted warning signs at the local beaches.

True, due to the ammonia levels in the urine, the sensors in the jellyfish's tentacles are disrupted and in that case stops them from stinging anything.

No. A sea anemone and a jellyfish would not meet. If they did meet, the jellyfish would sting the sea anemone and kill it.

Radial Keratotomy or RK is used to treat nearsightedness also known as myopia. This procedure was developed by Svyatoslav Fyodorov a Russian optamologist in 1974.

They have sex every 5 minutes in which they share oxygen with each other, this allows them to reproduce and breathe at the same time.

There are no electric jellyfish and there are no jellyfish named that.

You may be referring to many of the comb jellies that refract light into a brilliant display of moving rainbow colors along their comb rows by the waving of their cilia. In that case, the name of one of the most popular species (because it is prominently displayed at the Monterey Aquarium) is the Mertensia ovum, or 'sea nut' jelly. Unfortunately, even though comb jellies are gelatinous marine invertebrates, they aren't in the same order, class, or even phylum as jellyfish.

Most comb jellies, and many hydromedusa (closely related to jellyfish), such as Aequorea victoria and Atolla wyvillei, do exhibit bioluminescence in the dark. But alas, no sea jellies can produce electric shocks.

The syndrome is caused by a severe change (mutation) in the HPRT gene . Since the HPRT gene is located on the X chromosome, Lesch-Nyhan syndrome is considered an X-linked disorder and therefore only affects males.

Cnidaria

The temperature of the water around it. Cnidarians, like all animals except mammals and birds, are coldblooded, meaning they cannot regulate their own temperature. Their bodies have the same temperature as the environment. This is why lizards sunbathe, for example.

A Box Jellyfish can weigh up to 2 kg (4.4 lb) and some species have tentacles that can reach up to 3 m (9.8 ft) in length. Note however that even juvenile specimens can sting and, in certain circumstances, kill a human.

A jellyfish has radial symmetry. A jellyfish is part of the cnidaria species of animals and they generally have radial symmetry. Radial symmetric organisms are like a pie in terms of their shape. THey have no left or right sides. If you were to turn a radial symmetric animal on its side, it would like the same as it did prior.

Cannonball jellyfish live in warm, estuarian waters. They are found in the mid-west Atlantic Ocean and in the east-central and northwest Pacific Ocean.

* Jellyfish have nematocysts, or stinging cells used for defense and capturing prey. * They never stop growing. * They are actually older than dinosaur. * Box Jellyfish are the deadliest creatures in the world. * When removed from water, they collapse into a blob because of high water content * they are made of 95% water * they can absorb oxygen through their membrane-like skin * the amount of venom in a Box Jellyfish could kill 60 people * jellyfish kill more people than sharks * Upside-down Jellyfish has algae growing in its tentacles so it must live in shallow water. * The box jellyfish has 24 eyes, yet it still has blurry vision. * Jellyfish have no brain, respiratory system, circulatory system, or excretory system, so they use their mouth for "waste expulsion" * The Box Jellyfish has 64 anuses.
