“…Wishner and her colleagues have examined this fauna in some detail (Wishner 1980a, b, c, Wishner & Meise-Munns 1984, Gowing & Wishner 1986, Wishner & Gowing 1987. They refer to this environment as the benthopelagic or benthic boundary layer, as do Childress et al (1989). It has its own endemic fauna, phylogenetic aspects of which have been partially examined (Grice & Hulsemann 1970, Grice 1972, Wishner 1980c, Hargreaves 1984, Domanski 1986, Gowing & Wishner 1986, Childress et al 1989.…”
