Similarly, on approaching the Upper/Lower Bathyal Zone boundary (i.e. the shear zone between the AAIW and NADW masses), there is a large fall in abundance, that continues through the Lower Bathyal Zone (mean 39%, range 28-71%) into the Abyssal Zone (mean 20%, range 6-34%). Clearly, this species has a wide toler- ance of temperature and salinity, but it is relatively less successful in unstable, or mixed zones

Similarly, Krithe (together with one species of Parakrithe) and Cytheropte- ron are the two most diverse genera in the deep-water faunas off south-western Africa (12 species each), whereas in the Abyssal Zone the genus Krithe is the most abundant taxon.
