Adult males and females look totally different. Males are slate grey to dark brown with up to 14 distinct white stripes across the back going down the flanks. They have white spots on their thighs and belly. Females do not have manes or fringes of long hair.
They are restricted to reedbeds and adjacent grasslands of the Okavango and Chobe. During the annual flood they move out of the reedbeds for a short period.
As a herbivore, the nyala’s diet consists of foliage, fruits, flowers and twigs. During the rainy season they feed upon the fresh grass. They need a regular intake of water, and thus choose places with a water source nearby. Today the nyala are found in South African protected areas in the KwaZulu-Natal Game Reserves of Ndumo Game Reserve, uMkuze Game Reserve and Hluhluwe-Umfolozi Game Reserve, Kruger National Park and Sibuya Private Game Reserve. According to statistics of 1999, 10-15% of the nyala occur on private land.
The Kob is probably one of the most targeted edible saltwater fish off South Africa’s coastline and is known by many names in Southern Africa: Kob, Daga, Drum, Daga Salmon and Kabeljou. The Kob grow to big sizes and put heavy tackle to the test. They are also a great species to target on boats in estuaries with lures. Kob are aggressive fish and mainly move around in shoals where they feed on smaller fish and crustaceans.
Most adults migrate from the Cape to KwaZulu-Natal to spawn between August and November. Juveniles enter the upper reaches of estuaries where they remain until they about 15cm. The juveniles prefer the sandy or muddy substrates in shallow embayments.
Most kob species are voracious, shoaling predators and some species have become highly specialised for feeding in their muddy, murky environment. Their lateral line system (a sensory system found in all fish that enables them to detect vibrations and pressure changes in the water) is very well developed and this, in conjunction with the sensory barbles which some have on their snouts, makes the kob less reliant on sight when feeding. Small fish, crustaceans such as prawns and crabs, and molluscs such as squid and cuttlefish are all eaten by the various kob species.
