jellyfish possess two tissue types: endoderm and ectoderm, in addition to a single cell layer of jelly-like mesoglea between the endoderm and the ectoderm (Russell 21). Jellyfish exhibit radial symmetry and have tentacles with stinging cells known as cnidocytes. They range in size from a few millimeters up to a bell size of two meters across, with tentacles up to thirty-six meters long. Typically less than five percent of a jellyfish’s body is "solid organic material" (Halstead, Poisonous 96-97). Jellyfish
What is the role and purpose of the many eyes found on the box jellyfish Tripedalia cystophora? Introduction: The box jellyfish Tripedalia cystophora is a small jellyfish that can be at least 1cm long. Its bell is shaped somewhat like a square, which give it the name “box” jellyfish. Each of the four bottom corners of the bell have three tentacles. Even though it is in the same family as the sea wasp, T. cystophora is harmless. This jellyfish has been observed living in mangrove swamps where it
The most dangerous fish is the boxed jelly fish. It is the most venomous and deadliest sea creature. It will stun then it will kill its prey if you get stung then your skin will be badly damaged. It would be the worst sting you will feel in your life that is because it’s tentacles are hollow. It is 1 foot long and has 15 tentacles there are 29 species and almost extinct. Another one is is the deadly piranha. It likes to lives in freshwater by South America. It is fast at killing and has really sharp
jellyfish, corals, hydroids, and anemones. They are an ancient group of animals that are thought to have emerged more that 500 million years ago. They are characterized by their radial symmetry, their diploblastic bodies, and specialized cells called cnidocytes. Cnidarians are represented as either polyps or medusae. Sea anemones and corals are consistently found as polyps, and jellyfish have a polyp stage early in their development. These polyps are mostly sessile, but some have the ability to relocate
INTRODUCTION: The Animal Kingdom is generally believed to have originated in Archeozoic oceans long before the first fossil record. Every major phylum of animals has at least some marine representatives; some groups, such as cnidarians and echinoderms, are largely or entirely marine lives. From the ancestral marine environment, different groups of animals have invaded fresh water; some have moved onto land. There are over a million described species of animals. About 5% of this number are consists
By definition, symbiosis is the close and often long term interaction between two or more different species. The word symbiosis is derived from the Greek words, sym (together) and bio (life). German biologist Anton de Bary is the scientist typically credited with coining the term in the middle of the nineteenth century, though also an important contribution was made by his contemporary, Albert Bernhard Frank. Frank, however, instead used the term symbiotism. De Bary introduced the term to discuss
