Brief SummaryRead full entry
BiologySpawning occurs in June-August. T. tenuis most probably has a pelagic larval stage. Longevity is reported to be about five years. The species usually lies on the left valve, a few centimetres below the sediment-surface. its burrowing depth depends on the tide and exceeds 10 cm at low tide (Tebble, 1966; Wolff, 1973; Fish & Fish, 1989). T. tenuis is a suspension feeder with tendencies to selective deposit-feeding. lt takes vegetable detritus, but diatoms may also occur in the gut. Young flatfish often feed on the tips of the protruding siphons, which are subsequently regenerated (Wolff, 1973; Fish & Fish, 1989). T tenuis is sensitive to low winter temperatures and therefore shows low nurnbers after cold winters (Beukerna, 1979; Beukema & Essink, 1986).
