![]() With natural breeding attempts nixed for the northern white rhinos, conservationists have turned to in vitro fertilization. The two females are incapable of a successful pregnancy: Najin is too old and issues with her legs make it impossible for her to support the weight of a mounting male Fatu has a uterine condition that will likely keep her from breeding, according to experts. ![]() The captive northern white rhinos are two females - Najin, Sudan's daughter, and Fatu, Najin's daughter - which live in the Ol Pejeta Conservancy in Kenya. There are now only two northern white rhinos left in the world, both living in captivity, according to the World Wildlife Fund. On March 20, 2018, the conservancy announced the death of the last male northern white rhino, Sudan. He was not a victim of poaching, however, and the conservancy was investigating the cause of death. 18, 2014, Ol Pejeta Conservancy announced that one of them, one of the last two breeding males, had died. In 2009, four northern white rhinos were moved from a zoo in the Czech Republic to a private conservancy in Kenya in the hope that they would breed, according to the IUCN. However, the northern white rhino is considered "extinct" in the wild. Southern white rhinos have an increasing population there are 20,405 southern white rhinos. White rhinos are "near threatened," which means they may be considered threatened by extinction in the near future.The total population estimate in 2007 was 2,575 individuals, according to the IUCN. Fortunately, their population is increasing there are 3,333 greater one-horned rhinos in the world. Greater one-horned rhinos are "vulnerable," which means they may become endangered unless circumstances improve.There are 5,055 black rhinos, fewer than 100 Sumatran rhinos and only 35 to 44 Javan rhinos. Black rhinos, Sumatran rhinos and Javan rhinos are "critically endangered," which is the list's highest risk category.In Asian countries, male beetles are also used for gambling fights since they naturally compete for female beetles with the winner knocking the other off a log.A black rhino carcass with the horn hacked off. They are clean, easy to maintain and safe to handle. Rhinoceros beetles are popular childrens pets in Asia. In Brisbane they are only seen in the summer months, but in the tropical north they can be found at anytime of the year. They are generally noticed when they come to house lights or when they are seen lying beneath street lights and on the concrete tarmacs of petrol stations. Rhinoceros Beetles can fly strongly and are attracted to lights at night. That would be like an elephant carrying 850 elephants on its back. However, A huge African elephant can only carry up to 25% of its own weight on its back and as the Rhino Beetle can carry 850 times their own weight, there is no contest. You would also think something as massive as an elephant would be able to carry more weight than a little insect. To put this into perspective, if a human of average height and weight had the strength of the rhinoceros beetle, it would be able to lift a 65 ton object. They can lift up to 850 times their own weight. Rhinoceros beetles are the strongest animals on the planet, proportionally. As with all beetles, the Rhinoceros Beetle larvae (grubs) hatch from eggs and develop into pupae and these eventually develop into adult beetles. Their larval stage is long, several years in some species. If a squeaking beetle is examined closely, the abdomen can be seen moving in time with the squeaks. The hissing squeak is merely a bluff and is produced by rubbing the abdomen against the ends of the wing covers. The fearsome appearance of these beetles is increased by the loud hissing squeaks they give when disturbed. During the day, they hide under logs or in vegetation and are invisible from the few predators big enough to want to eat them. The best protection they have from predators is their usually large size combined with being nocturnal (activity being at night). Using its horns, it can dig its way out of a sticky situation by burying itself underground, escaping danger. ![]() Scientists believe that the beetle has become so strong to be able to forage through heavy litter on the jungle floor and dig its way to safety. The male Rhinoceros Beetles use their horns in mating battles against other males.
