Oceanography & Marine Biology Annual Review 39, 207-231 Selected higher taxon - equivalent terrestrial examples - Coccinellidae for all beetles Recording conspicuous species by visual methods - method to be used by scuba divers in subtidal, while walking at low tide in the intertidal. Number of species - ATBI - All Taxa Biodiversity Inventory - identification of all species from restricted area, from viruses to whales. Practically not done before, several sites are having quite complete inventories.
