- Description: Off South Africa, the ragged-tooth shark Carcharias Taurus has been occasionally reported from the West Coast, but it is more commonly found along the East and South coasts from Cape Town to northern KwaZulu-Natal (KZN) (Bass et al. 1975, Smale 2002). Mating is thought to occur off the south coast of KZN from October to late November (G Cliff, Natal Sharks Board, unpublished data). Pregnant females then move northward to spend the early part of their gestation in the warmer waters of northern KZN and possibly southern Moçambique. During July and August, the near-term pregnant females begin to move southwards towards the cooler waters of the Eastern Cape (Wallett 1973, Bass et al. 1975, G Cliff, unpublished data), where they give birth from September to November (Smale 2002). After parturition, many of the females migrate back to KZN. The whereabouts of mature males outside of the mating season is unclear. These broadscale distribution and migratory habits for C. taurus have been inferred from limited catch records obtained for only parts of its range along the South African coast.

- Description: In this article we explore the possible contribution of the Web in promot-ing the use and status of African languages. Participation in sharing and producing knowledge through the Web can play a key role in the eco-nomic, social and educational development of Africa. While physical ac-cess to information is hampered by lack of infrastructure and connectivi-ty, epistemological access is hampered by the use of English. Re-sources in African languages are available. Until the amount of Web content and the number of users reach critical mass, these resources play a symbolic rather than an instrumental role in promoting African lan-guages. The use of electronic resources available on the Web could contribute to cutting the printing and transport cost of paper material, es-pecially in multilingual settings where many languages would have to be represented. Another practical way in which the Web can promote the development of African languages is to promote communication among their speakers. This is already showing its potential by allowing experts from various disciplines to work collaboratively on the development of new indigenous terminology through mailing lists and chat rooms. On a larger scale, the Web can play a unifying function among speakers of different varieties of the same African language.
