The Okavango Delta is a unique pulsing wetland where the 1,600 km (990 mi) long Okavango River reaches a tectonic trough in the middle of the Kalahari Desert in northern Botswana. Each year approximately 11 cubic kilometers of water spreads over the 6,000-15,000 km2 area. It is on the UNESCO World Heritage List as well as one of the Seven Natural Wonders of Africa.(1)

Four of the five species of the big cats (the Panthera genus – lion, tiger, leopard, jaguar and snow leopard), the exception being the snow leopard can hybridize with each other to produce numerous hybrids. In fact, breeding of two different pantheras has been banned in many zoos and animal sanctuaries due to no conservation value of the hybrid, and the risk it poses on the mother that gives birth to it. For instance, the liger’s increased growth rate and enormous size can cause the tigress giving birth to have a difficult delivery, endangering both the mother and her liger cubs, which may be born prematurely or require a Caesarian. Common problems in cubs that survive are neurological disorders, obesity, genetic defects, and a shortened lifespan; though a few have reportedly made it to their twenties, many don’t survive past the age of seven. Moreover, male ligers have lowered testosterone levels and sperm counts, rendering them infertile while females, though capable of reproducing with either a lion or a tiger, often give birth to sickly cubs that don’t survive. However, hybrids do occur by accident in captivity. Here are the list of possible hybrid big cats below.
