Red Paper Lantern Jellyfish
''Pandea rubra'' is a species of hydrozoans distinguished by an anthomedusan jellyfish with a bright red subumbrella. ''P. rubra'' are found in extremely deep and cold Pacific Ocean waters. Nomenclature Red paper lantern jellyfish is a common name for this animal because of its mantle that can crumple up or expand like a paper lantern. Another reason for the name was because it was first seen on the coast of Japan and was seen as sacred. Anatomy The red paper lantern is the most common type of ''P. rubra'' that has been recorded. This medusa has a transparent, bell-shaped hood measuring about 10 centimeters in diameter and 17 centimeters from top to bottom, with between 14 and 30 tentacles that extend up to 6 times the length of its body. Inside the transparent hood is a deep red colored mantle. JAMSTEC researcher Dr. Dhugal Lindsay is credited with naming it the paper lantern. Range and habitat ''P. rubra'' has only been found in deep and cold ocean waters at only a few sites. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrozoans
Hydrozoa (hydrozoans; ) are a taxonomic class of individually very small, predatory animals, some solitary and some colonial, most of which inhabit saline water. The colonies of the colonial species can be large, and in some cases the specialized individual animals cannot survive outside the colony. A few genera within this class live in freshwater habitats. Hydrozoans are related to jellyfish and corals and belong to the phylum Cnidaria. Some examples of hydrozoans are the freshwater jelly ('' Craspedacusta sowerbyi''), freshwater polyps ('' Hydra''), ''Obelia'', Portuguese man o' war (''Physalia physalis''), chondrophores (Porpitidae), " air fern" (''Sertularia argentea''), and pink-hearted hydroids ('' Tubularia''). Anatomy Most hydrozoan species include both a polypoid and a medusoid stage in their lifecycles, although a number of them have only one or the other. For example, ''Hydra'' has no medusoid stage, while '' Liriope'' lacks the polypoid stage. Polyps The hydroi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
