This was demonstrated for polychaete and molluscan taxa from the equatorial Seychelles relative to their counterparts at high latitudes in the Atlantic and Pacific (Mackie and others, 2005). Another example of the non-generality of the relationship between latitude and diversity is that of MacKay and others (in press), who found that the soft sediment shelf macrobenthos of the central KwaZulu-Natal Bight on the east coast of South Africa (~28-29°S) are abundant and rich, and are comparable to some of the highest levels of richness in marine unconsolidated sediments found elsewhere, as reported by Gray and others (1997). The Annelida were dominated by Polychaeta which were particularly diverse (49 families).
