Tripedalia Maipoensis
''Tripedalia'' is a genus within the family Tripedaliidae that is part of the box jellyfish, also known as the Cubozoa. There are only three known species within ''Tripedalia'': '' T. cystophora'', '' T. binata'' and '' T. maipoensis''. Biology ''Tripedalia'' are relatively small in size, ranging from 11 to 15 mm. Both species have a cuboid bell and are transparent with a yellowish to brownish color. Their bells contain nematocyst warts that are mainly around the outline of '' T. cystophora'' and are thinly spread throughout '' T. binata''. As part of the Cubozoans, ''Tripedalia'' have knife-shaped pedalia, and their padalial canals are also bent. They have bead-like structured tentacles, and both species have flat stomachs with four gastric pouches. Inside their gastric pouches are butterfly-shaped gonads separated by interradial septa. Distribution and habitat The ''T. cystophora'' has been documented in various locations across the globe. They have been observed in th ...

Box Jellyfish
Box jellyfish (class Cubozoa) are cnidarian invertebrates distinguished by their box-like (i.e., cube-shaped) body. Some species of box jellyfish produce potent venom delivered by contact with their tentacles. Stings from some species, including '' Chironex fleckeri'', '' Carukia barnesi'', '' Malo kingi'', and a few others, are extremely painful and often fatal to humans. Taxonomy and systematics Historically, cubozoans were classified as an order of Scyphozoa until 1973, when they were put in their own class due to their unique biological cycle (lack of strobilation) and morphology. At least 51 species of box jellyfish were known as of 2018. These are grouped into two orders and eight families. A few new species have since been described, and it is likely that additional undescribed species remain. Cubozoa represents the smallest cnidarian class with approximately 50 species.

Tripedalia Cystophora
''Tripedalia cystophora'' is a small species of box jellyfish in the family Tripedaliidae. It is native to the Caribbean Sea and the Central Indo-Pacific. Description The medusa of ''Tripedalia cystophora'' is about in diameter. Its boxy dome-shaped bell has a flattened top and is slightly wider than it is high. From a single point on each of the four corners of the bell arise three tentacles, each on a pedalium or stalk. The outer surface of the bell is granulated with small wart-like structures armed with nematocysts. About a quarter way up the bell are four rhopalia, cylindrical structures containing light-sensitive cells. About halfway up the bell, the four flattened gonads can be seen on the inside of the bell. The underside of the bell is partially constricted by a velarium, a horizontal ring of tissue, and in the centre is a manubrium, a tube-like structure which hangs down with the mouth at its tip. This box jellyfish is a translucent yellowish-brown colour. Distributio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tripedalia Binata
''Tripedalia'' is a genus within the family Tripedaliidae that is part of the box jellyfish, also known as the Box jellyfish, Cubozoa.

Cubozoa
Box jellyfish (class Cubozoa) are cnidarian invertebrates distinguished by their box-like (i.e., cube-shaped) body. Some species of box jellyfish produce potent venom (poison), venom delivered by contact with their tentacles. Stings from some species, including ''Chironex fleckeri'', ''Carukia barnesi'', ''Malo kingi'', and a few others, are extremely painful and often fatal to humans. Taxonomy and systematics Historically, cubozoans were classified as an order of Scyphozoa until 1973, when they were put in their own class due to their unique biological cycle (lack of strobilation) and morphology. At least 51 species of box jellyfish were known as of 2018. These are grouped into two Order (biology), orders and eight Family (biology), families.

Mai Po Marshes
Mai Po Marshes (; Hong Kong Hakka: ''Mi3bu4 Sip5ti4'') is a nature reserve located in San Tin near Yuen Long in Hong Kong. it is within Yuen Long District. It is part of Deep Bay, an internationally significant wetland that is actually a shallow estuary, at the mouths of Sham Chun River, Shan Pui River (Yuen Long Creek) and Tin Shui Wai Nullah. Inner Deep Bay is listed as a Ramsar site under Ramsar Convention in 1995, and supports globally important numbers of wetland birds, which chiefly arrive in winter and during spring and autumn migrations. The education center and natural conservation area is wide and its surrounding wetland has an area of 1500 acres (6 km2). It provides a conservation area for mammals, reptiles, insects, and over 350 species of birds. The reserve is managed by the World Wide Fund for Nature Hong Kong since 1983 and WWF runs professionally guided visits for the public and schools to the reserve; the Agriculture, Fisheries and Conservation D ...

Copepod
Copepods (; meaning 'oar-feet') are a group of small crustaceans found in nearly every freshwater and saltwater habitat (ecology), habitat. Some species are planktonic (living in the water column), some are benthos, benthic (living on the sediments), several species have Parasitism, parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as swamps, under leaf fall in wet forests, bogs, springs, ephemeral ponds, puddles, damp moss, or water-filled recesses of plants (phytotelmata) such as bromeliads and pitcher plants. Many live underground in marine and freshwater caves, sinkholes, or stream beds. Copepods are sometimes used as Ecological indicator, biodiversity indicators. As with other crustaceans, copepods have a larval form. For copepods, the egg hatches into a Crustacean larvae#Nauplius, nauplius form, with a head and a tail but no true thorax or abdomen. The larva molts several times until it resembles the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
