Taxonomic remark The use of the name ‘Spence Bate’ instead of ‘Bate’ is discussed herein. See page 201. [details]Unreviewed
Biology Generally, breeding behaviour of infaunal amphipods like P. altamarinus is influenced by location. In deeper waters the spring rise in temperature initiates breeding, while in shallower waters it is induced by tidal phasing (Fincham, 1971). Oedicerotids, the amphipod family to which P. altamarinus belongs, burrow through the surface layer of the sediment while feeding. They only use the mouth parts and the gnathopods for collecting food. Aquarium investigations have shown that they ingest loose detritus sifted from the mud and water interface or gathered by the maxillipeds from the material passed to them by the gnathopods (Enequist, 1949). Apparently, P. altamarinus can switch foods at different times of the year: harpacticoids in summer and diatoms and other algae scraped from sand grains in winter (Beare & Moore, 1994). [details]
Description Amphipod with relatively robust body up to 7 mm long. The eyes are very large and round. Its colour
varies between white and yellow with clear brown patches. The head has a short, pointed rostrum
arched downwards. [details]
Distribution In the 1976-1986 period Pontocrates altamarinus was found to occur across the entire Belgian part of the North Sea, with the exception of the coastal zone. This distribution pattern was extended by observations in the coastal zone in the 1994-2001 period. In both periods P. altamarinus had a low distribution frequency and relatively low densities (1976-1986 period: maximum 130 ind./m2; 1994-2001 period: maximum 30 ind./m2). [details]
Distribution P. altamarinus can be observed most frequently in the area south of the 30 m isobath and is locally very common between 53'30'N and 52'30'N. The species is also found in the sublittoral of the western part of the Dutch Wadden Sea and in the eastern part of the Oosterschelde. lt has also been recorded in the marine pad of the Westerschelde (Cattrijse et al., 1993). [details]
Habitat Pontocrates altamarinus appears in different sediment types but always with a relatively low occurrence (< 30%). A clear preference for a certain sediment type cannot be identified. [details]
Habitat This amphipod prefers bottoms of fine and medium sand with a low percentage of silt. [details]
Morphology This amphipod has a robust body, up to 7 mm in length. The eyes are very large and rounded. The body is whitish or yellowish in colour, with distinctive dark brown patches. The head has a short down turned, pointed rostrum (Lincoln, 1979; Fish & Fish, 1989; Hayward & Ryland, 1990). [details]
