It will be criticial for the voices of those working in the field to protect threatened species such as African Rhinos to be amplified in coming years as we set the conservation agenda for the next decade.” International, national and local actors need to work together to tackle the biodiversity crisis. “It is crucial that local people are increasingly involved in and benefit from conservation efforts. “These developments for African rhinos show the changes that can be achieved through committed conservation action,” said Dr Jane Smart, Global Director of the IUCN Biodiversity Conservation Group. “It is essential that the ongoing anti-poaching measures and intensive, proactive population management continue, with support from national and international actors." At the same time, it is evident that there is no room for complacency as poaching and illegal trade remain acute threats," said Dr Grethel Aguilar, Acting Director General of IUCN. "While Africa’s rhinos are by no means safe from extinction, the continued slow recovery of Black Rhino populations is a testament to the immense efforts made in the countries the species occurs in, and a powerful reminder to the global community that conservation works. The IUCN Red List now includes 116,177 species of which 31,030 are threatened with extinction. Population models predict a further slow increase over the next five years, according to today’s update. A giraffe can send blood through these smaller blood vessels into the middle of each patch to release heat from the body.Between 20, the Black Rhino ( Diceros bicornis) population across Africa has grown at a modest annual rate of 2.5% from an estimated 4,845 to 5,630 animals in the wild, respectively. Their spots also have far more use than the obvious camouflage they provide and around each spot is a large blood vessel which branches off in a complex system of blood vessels underneath the spot. Spots: Each giraffe has a pattern of spots that is completely unique to them, much like a humans’ fingerprint. Interestingly male giraffes often have thicker ossicones than females, which become bald on top due to frequent necking. Both males and females are born with their ossicones but they lie flat at birth and are not attached to the skull in order to avoid injury to themselves and the mother, fusing to the skull as they grow older. Horns: Giraffes' horns are actually known as ossicones and are found in both males and females, they are formed from ossified cartilage and covered in skin and hair. The giraffe’s neck has a very complex system that regulates their blood pressure, ensuring that plenty of blood gets to their brain but not too much when they bend down to take a drink. This is a ritualised fight that appears to help establish dominance, and involves repeatedly swinging their neck to deliver head-butts to the other bull on their body and belly. The neck is also used for ‘necking’ in Bulls. This allows giraffes to reach the highest leaves and shoots up in the Acacia tree (their favourite food source), which others browsers cannot reach, whilst also keeping an eye out for predators from their vantage point. Neck: One of the distinguishing characteristics of a giraffe is its long neck.
