![]() The high abundance and presence of juvenile and adult animals may have major economic impacts on a high-value industry, given the potential of the population to spread to shrimp farms located in tropical mangroves. They’re named after the Cassiopeia constellation in the sky, which appears upside down. These creatures live their lives upside down but are headed in the right direction. They evolved creative ways to get energy in shallow, sandy and muddy environments where they are found. Only female jellyfish were observed, which suggests that the maintenance and spread of the non-indigenous population occur by asexual reproduction. Cassiopea jellyfish are highly versatile. andromeda along the Brazilian equatorial margin. In addition, we report the northward expansion of C. In its place are multiple secondary mouths contained within the frilly oral arm branches. The results indicate that the jellyfish in aquaculture systems are similar in terms of morphology and genetics to those found in natural environments in Bermuda, Egypt, Hawaii, Florida, and elsewhere in Brazil (Rio de Janeiro) and are related to specimens originally inhabiting the Red Sea ( Cassiopea andromeda). Because Cassiopea belong to the Order Rhizostomeae, they do not possess tentacles or a primary mouth, in contrast to other commonly studied jellyfish such as A. The observed specimens were collected on the equatorial Southwestern Atlantic coast (Northeast Brazil) for identification by genetic sequence data (COI). Herein, for the first time, we describe the occurrence of the upside-down jellyfish (genus Cassiopea) in shrimp ( Litopenaeus vannamei) farms. Jellyfish, when found in aquaculture systems, may cause major economic damage they are already present in many aquaculture facilities in the Mediterranean, Yellow Sea, and Bohai Sea. "It's one of those papers that I do think will open up a door to a new line of study that's worth pursuing.Invasive species are one of the biggest threats to coastal areas. #Cassiopeia jellyfish skin"We can't look at it as, hey, we're going to harvest these jellyfish and turn it into a skin cream," said Graham. Grahan told Reuters that there was no immediate commercial value from the new findings. The Mangrove Jellyfish Cassiopea, also called the ‘upside-down jellyfish’ for reasons I needn’t dwell on, is the only member of its particular jellyfish family. It's hoped that unraveling the mysteries of the immortal jellyfish will help provide clues for human aging. They also appeared to be better at maintaining the ends of chromosomes called telomeres - in humans and other species, telomere length has been found to shorten with age. The zooxanthellae helps the jellyfish obtain most of its. dohrnii's genome might make it better at copying and repairing DNA. The up-side down jellyfish has a symbiotic relationship with zooxanthellae, located in their mesoglea. dohrnii isn't the only cnidarian species to self-rejuvenate, but this ability is usually lost once the animals reach sexual maturity, the scientists said. #Cassiopeia jellyfish fullThey were then able to present the full range of mRNA expressed by the jellyfish at different stages of the life cycle reversal process. Scientists compared a set of almost 1,000 genes linked to aging and DNA repair between T. "We've known about this species being able to do a little evolutionary trickery for maybe 15-20 years," Monty Graham, a jellyfish expert and director of the Florida Institute of Oceanography, who was not involved in the research, told news agency Reuters. This jellyfish is dioecious an adult female jellyfish produces eggs and holds them until a male jellyfish releases sperm into the water. ![]()
