“…Observations of LuTHER (1958) and MACNAE and KALK (1962) accord generally with this. In fact, it is also commonly observed underwater that Amblyeleotris japonicus exhibit quick withdrawal into burrows, thereby Alpheus bellulus are secured in them without fail, when fishes such as Fugu pardale, G'erres oyena and Pagrus major, that are foraging over the bottom and gather immediately where the bottom sand is dug up, approach their burrows within a half metre or so.…”

“…Apart from these, MACNAE (1957) has recorded an association between Alpheus crassimanus and Gobius nudiceps from mudflats of Port Elizabeth, South Africa. In addition, MACNAE and KALK ( 1962) have also listed partnerships between snapping shrimp and gobioid fish in Mo<;ambique water, in which included are Alpheus rapax and A. rapacida with Cryptocentrus octofasciatus and Gobius delagoae in the lower midlittoral and infralittoral fringe, and Alpheus malabaricus with Butis butis on soft mudflats.…”

“…TAKAGI ( 1966) recognizes for the Japanese gobioid fish nine ecological types and assigns those sharing the burrow with snapping shrimp tb the commensal type, while he includes apparently unduly those utilizing the burrows of other animals 'parasitically' into the burrowing type. MACNAE and KALK ( 1962) mention the interrelations as partnership generally, but in part denote the gobioid fish as commensal with the snapping shrimp. HERALD ( 1961), on the contrary, regards his example as symbiotic relationship.…”

“…Although sediments in Kbnigshafen are relatively coarse grained, the macrofauna closely resembles those of other tidal areas in north western Europe (see Wohlenberg, 1937), and the species composition in the tidal zone has remained relatively stable over the last decades (Reise, 1982). From these areas and also from other tidal flats in the world, high abundances of grazers are well known (Macnae & Kalk, 1962;DSrjes, 1978;Pace et al, 1979;Branch & Branch, 1980;Race, 1982).…”

In three intertidal sand bottom communities of the "K6nigshafen" (Island of Sylt, North Sea), the biomass production and respiration of phytobenthos, phytoplankton, macrozoobenthos, and in situ community metabolism were measured monthly during 1980. The study sites were characterized by different communities (Nereis-Corophium-belt, seagrass-bed, Arenicola-flat) and by a high abundance of the mollusc Hydrobia ulvae. Benthic diatoms are the major constituents of plant biomass in the Arenicola-flat. In this community, gross primary productivity amounts to 148 g C m-2 a-1.82 % of this productivity is caused by microbenthos, whereas phytoplankton constitutes only 18 %. In the seagrass-bed, gross primary productivity amounts to 473 g C m -2 a -1. 79 % of this is generated by seagrass and its epiphytes, whereas microphytobenthos contributes 19 %. In the Nereis-Corophium-belt, only microphytobenthos is important for hiomass and primary productivity (gross: 152 g C m -2 a-l). Annual production of macrofauna proved to be similar in the A_renicola-flat (30 g C m -2 a -1) to that in the seagrass-bed (29 g C m -2 a-l). Only one third of this amount is produced in the Nereis-Corophium-belt (10 g C m -2 a-l). The main part of secondary production and animal respiration is contributed by grazing H. ulvae. In the seagrass-bed, 83 % of the energy used for production is obtained from the grazing food chain. In the Arenicola-flat and the NereisCorophium-belt, the importance of non-grazing species is greater. A synchrony of seasonal development of plant biomass and monthly secondary production was observed. In the Arenicolaflat and the seagrass-bed, where density and production of macrofauna are high, a conspicuous decrease in biomass of microbenthos occurs during the warmer season, whereas in the NereisCorophium-belt primary production causes an increase in microphytobenthic biomass in summer and autumn. Energy flow through the macrofauna amounts to 69 g C m -2 a -~ in the Arenicola-flat, 85 g C m -~ a -1 in the seagrass-bed and 35 g C m -2 a -1 in the Nereis-Corophium-belt. Based on the assumption that sources of food are used in proportion to their availability, 49 g C m -2 a -1 (Arenicola-fiat), 72 g C m -2 a -1 (seagrass-bed) and 26 g C m -2 a -1 (Nereis-Corophium-belt) are estimated as taken up by the grazing food chain. All three subsystems are able to support the energy requirements from their own primary production and are not dependent on energy import from adjacent ecosystems.

This first account, dedicated to the shallow water marine heterobranch gastropods of Mozambique is presented with a focus on the clades Acteonoidea and Cephalaspidea. Specimens were obtained as a result of sporadic sampling and two dedicated field campaigns between the years of 2012 and 2015, conducted along the northern and southern coasts of Mozambique. Specimens were collected by hand in the intertidal and subtidal reefs by snorkelling or SCUBA diving down to a depth of 33 m. Thirty-two species were found, of which 22 are new records to Mozambique and five are new for the Western Indian Ocean. This account raises the total number of shallow water Acteonoidea and Cephalaspidea known in Mozambique to 39 species, which represents approximately 50 % of the Indian Ocean diversity and 83 % of the diversity of these molluscs found in the Red Sea. A gap in sampling was identified in the central swamp/mangrove bio-region of Mozambique, and therefore, we suggest that future research efforts concentrate on or at least consider this region.
