Notes 
From other sources
Unreviewed: has not been verified by a taxonomic editorBiology The larvae occur in the plankton frorn June-July to September- November, often in large quantities. The planktonic stage lasts for about 4 weeks. M. bidentata has a maximum life span of 7 years (Wolff, 1973; Ockelmann & Muus, 1978; O'Foighil et al., 1984).
M. bidentata is a commensal of a number of hosts. It has been found together with the brittle stars Acrocnida brachiata and Amphiura filiformis and in the burrows of the sipunculid Golfingia. However, the species seems to be able to live without any host (Popham, 1940; Tebble, 1966; Wolff, 1973; O'Foighil et al., 1984; Hayward & Ryland, 1990).


M. bidentata is a suspension feeder (Wolff, 1973). Various infaunal invertebrates, e.g. the polychaetes Nephtys and Lumbrineris, prey on the juveniles. Small individuals have moreover been found in the gut of Echinocardium cordatum (Ockelmann & Muus, 1978).


In the Dutch Wadden Sea the species does not survive extremely cold winters (like in [details]


Unreviewed: has not been verified by a taxonomic editorDescription A thin, oval shell measuring 3 mm long. The outside is smooth with a sculpture of fine concentric
growth lines located close to each other. The colour of the shell varies from yellowish white to dark
reddish brown. Frequently lives in association with the brittle star Acrocnida brachiata[details]

Unreviewed: has not been verified by a taxonomic editorDistribution Although Mysella bidentata can be found across the entire Belgian part of the North Sea, the species mainly occurs in the near-coastal zone. In this zone the species reaches a high relative occcurence. In the 1976-1986 period the species was found to occur commonly in the eastern coastal zone, whereas Mysella bidentata was almost completely absent in that area in the 1994-2001 period. During both periods the maximum density was 4,000 to 4,500 ind./m2. [details]

Unreviewed: has not been verified by a taxonomic editorDistribution M. bidentata is very abundant at the Oyster Ground, where high densities of A. filiformis (q.v.) occur, but is also found in the Southern Bight and in the Delta area. In the latter area it is present in high numbers in the Grevelingenmeer and the northern part of the Oosterschelde. In the Dutch Wadden Sea, M. bidentata is present from the Balgzand in the western part up to the entrance of river Ems. Due to its small size biomass values are modest with maxima at the Frisian Front. [details]

Unreviewed: has not been verified by a taxonomic editorHabitat Mysella bidentata can be observed in all sediment types to be found on the Belgian part of the North Sea. The species nevertheless tends to prefer fine-grained sediments (median grain size 50-250 μm) with a mud content of 10-40%. In sediments with a mud content of 20-30% a relative occurrence of 90% can be observed. [details]

Unreviewed: has not been verified by a taxonomic editorHabitat The distribution pattern of M. bidentata suggests a preference for muddy fine sand, although the species is also found in clean sand. [details]

Unreviewed: has not been verified by a taxonomic editorMorphology The shell is thin and fragile, oval in outline. Large specimens reach only 3 mm in length. A sculpture of fine, closely spaced, concentric lines covers the shell. Growth stages are clearly visible. The colour of the shell varies from yellowish white to dark reddish brown and is darkest in the region of the umbo. The inside of the shell is white or translucent (Popham, 1940; Ockelmann & Muus, 1978; Hayward & Ryland, 1990). [details]
