MANTIS SHRIMPS OFF THE SUFFOLK COAST

THE OCCURRENCE OF MANTIS SHRIMP RISSOIDES DESMARESTI (CRUSTACEA: STOMATOPODA) OFF THE SUFFOLK COAST J. R. ELLIS, K. WARR, K. COOPER AND I. J. DE BOOIS Little is known about the distribution of mantis shrimps (Order Stomatopoda) in European seas, as these burrowing crustaceans are poorly sampled in trawl surveys. Two species are known to occur in British seas, Rissoides desmaresti (Risso, 1816) (formerly Meiosquilla desmaresti; see Manning & Lewinsohn (1982)) and Platysquilla eusebia (Risso, 1816) (Mauchline, 1984), though more species occur further south (Manning, 1977). Rissoides desmaresti (Fig. 1) is most often reported from the Mediterranean, where it is common in the western basins (Manning, 1977) and reported occasionally in eastern basins, such as the Aegean Sea (e.g. Kocataú, 1981). Its distribution extends northwards to the southern and western coasts of the British Isles, and it has been recorded regularly from the English Channel (Bell, 1853; Clark, 1985; Herbert, 2001), and Ramsay and Holt (2001) recently recorded a population in Tremadog Bay (North Wales). Within the North Sea (Fig. 2), single specimens of adult R. desmaresti have been recorded near the Kentish Knock lightship (51º39’N, 1º41’E) in April 1901 (Bell, 1902) and further north (53º42’N, 3º52’E) in January 1963 (van der Baan & Holthuis, 1966). The latter study also made reference to “not quite adult specimens” being recorded at the Brown Bank (either 52º44’N, 3º39’E or 52º41’N, 3º40’E) in September 1904. Even though there have been very few reports of adult stomatopods in the North Sea, their larval stages are more regularly reported (van der Baan & Holthuis, 1966, 1969; Verwey, 1966). Based on the duration of the larval stages and currents in the southern North Sea, Verwey (1966) suggested that it was likely that these larvae had originated not only from the English Channel, but also from the southern North Sea itself. Despite the indication that there is

Furthermore, they are not listed in the marine fauna of Suffolk (Anon, 1934) or Norfolk (Hamond, 1971). Occasional specimens of R. desmaresti were observed in Hamon grab and beam trawl catches during studies of gravel extraction sites and surrounding areas east of Felixstowe, and individual specimens were recorded in the Dutch Beam Trawl Survey of the southern North Sea in 2003 and 2004 (Table 1). In April 2006, a survey of gravel habitats east of Felixstowe yielded several specimens in both 2-m beam trawl and 4-m beam trawl samples (Table 1). No mantis shrimps were observed in the catches of Agassiz trawl taken on the same grounds during this survey, possibly as this gear does not dig into the sediment as much as beam trawls. There are also some more recent records of stomatopod larvae in the southern North Sea from the Continuous Plankton

Recorder (CPR), including some in close proximity to the location of the observed adults (Fig. 2). This may indicate that a breeding population of R. desmaresti, as suggested to occur in the southern North Sea by Verwey (1966), may occur off the coast of East Anglia. Rissoides desmaresti has been recorded in several shallow-water habitats, including muddy bottoms with sea grass (e.g. Zostera and Posidonia), sandy and muddy-sandy bottoms with bryozoans (e.g. Cellaria), and sediments containing a mixture of mud, sand and gravel (Kocataú, 1981; Clark, 1985; Ramsay & Holt, 2001). Its bathymetric range extends to about 80 m (Kocataú, 1981), though in British waters it tends to be recorded in waters of less than 40 m. The present specimens were all found in waters of 26–40 m depth, with the Dutch beam trawl survey recording a specimen from 52 m deep, and the sediments were comprised of a muddy-gravel with some pebbles.
