__FORCETOC__ ==Definition== *''according to Hottinger (2006):'' '''SPIKE''' - minute, conical to elongate spine-like projection on surfaces of the external wall of lamellar foraminifera, not thickened by [[secondary lamination]]. Spikes occur often on the walls deeply inside [[interlocular space]]s, as in the [[fossette]]s of larger elphidiids, to fend off larger particles such as diatom frustules transported with the food into the canal system by the pseudopods. ==See also== * [[fossette]] * [[interlocular space]] * [[secondary lamination]] ==References== Hottinger (2006), [http://paleopolis.rediris.es/cg/CG2006_M02/index.html Illustrated glossary of terms used in foraminiferal research].
