The species is restricted to the deeper central part of each shell, away from the margin. Peripheral abrasion of the shell{\textquoteright}s surface, which might have removed marginal settlement, is rejected as the major agent in producing the observed distribution. A number of larval behaviour mechanisms that might have been responsible are therefore considered. All are discounted except one: that the larva crept up the slope of the shell{\textquoteright}s inner surface towards the highest point (geonegative movement) before fixation. This hypothesis seems to explain many details of the settlement pattern. C. puncturata apparently exploited the shell{\textquoteright}s major concavity as a refuge from physical disturbance in a high-energy environment, and its larval settlement behaviour appears to have been specialized for concavo-convex (bivalve) substrates. A second category of refuge, minor local concavities anywhere on the shell{\textquoteright}s surface, was occupied during the vulnerable early astogenetic stages of two other bryozoan species, both with a runner-like colony morphology.}, author = {Bishop, J.D.D.} } @article {14, title = {Puellina (Bryozoa; Cheilostomatida; Cribrilinidae) from British and adjacent waters}, journal = {Bulletin of the British Museum (Natural History), Zoology series}, volume = {53}, year = {1987}, month = {09/1987}, chapter = {1}, isbn = {0 565 050338}, issn = {0007-1498}, author = {Bishop, J.D.D. and Househam, B.C.} } @article {13, title = {The genera Cribrilina and Collarina (Bryozoa: Cheilostomatida) in the British Isles and the North Sea Basin, Pliocene to present day}, journal = {Zoologica Scripta}, volume = {23}, year = {1994}, chapter = {225}, author = {Bishop, J.D.D.} } @article {12, title = {Type and figured material from the {\textquoteright}Pliocene Bryozoa of the Low Countries{\textquoteright} (Lagaaij, 1952) in the collection of the the Royal Belgian Institute of Natural Sciences}, journal = {Institute Royal des Sciences Naturelles de Belgique, Documents de Travail}, volume = {37}, year = {1987}, chapter = {1}, author = {Bishop, J.D.D.} } @article {6, title = {SEM Atlas of type and figured material from Robert Lagaaij{\textquoteright}s {\textquoteright}The Pliocene Bryozoa of the Low Countries{\textquoteright} (1952)}, journal = {Mededelingen Rijks Geologische Dienst}, volume = {43}, year = {1989}, chapter = {1}, isbn = {90-72869-03-6}, author = {Bishop, J.D.D. and Hayward, P.J.} }
