project researchers Brad Klausen, Gary Osborn and Chance Gardner. “They seem to have synergized art and science in an ingenious way that indicates both the form and function of key components of the brain.”
Easter actually began as a pagan festival celebrating spring in the Northern Hemisphere, long before the advent of Christianity. Easter was originally the celebration of Ishtar, the Assyrian and Babylonian goddess of fertility and sex.
With their huge number of venomous stinging cells, jellyfish aren't very cuddly. A few have been observed engaging in social feeding behavior, but for the most part, they're loners.
Severe box jellyfish stings can be fatal, triggering cardiac arrest in your body within minutes. Less severe stings may only cause symptoms like pain and irritated red tracks along your body, but they may not be deadly.
One jellyfish species, Turritopsis dohrnii, is virtually immortal. As the jelly ages, it eventually settles onto the sea floor and becomes a colony of polyps (individual organisms).
Even though some jellyfish have very long tentacles, they never get tangled up or sting them. That's because the tentacles are very slippery and only sting other species of jellyfish.
Jellyfish have no brain, heart, bones or eyes. They are made up of a smooth, bag-like body and tentacles armed with tiny, stinging cells. The jellyfish's mouth is found in the centre of its body.
Medusa, stage of a jellyfish, they can reproduce sexually by releasing sperm and eggs, forming a planula. The polyps clone themselves and bud, or strobilate, into another stage of life, called ephyra then grows into the adult medusa jellyfish.
Jellyfish reproduce both sexually and asexually. One generation (the medusa) reproduces sexually and the next generation (the polyp) reproduces asexually.
Fossil jellyfish are rare, scientists have to look for so-called "soft fossils," when organisms are quickly buried in sediment, leaving an imprint in the rock. Fossil Record Reveals Jellyfish More than 500 Million Years Old.
Thus, the NRC concluded that fluoride is an endocrine disrupter that can affect thyroid function at intake levels as low as 0.01 to 0.03 mg/kg/day in individuals with iodine deficiency.
