Limpets and Their Algal Epibionts: Costs and Benefits of Acrosiphonia spp and Ulva lactuca Growth

Table 2

Water velocities (m/s) required to generate sufficient drag to dislodge a clamped (25 N to remove) and relaxed limpet (2 N to remove). Values are predicted based on extrapolation of a nonlinear regression model.

	With Acrosiphonia	Acrosiphonia removed	With Ulva	Ulva removed
Clamped limpet	28.9	37.0	51.4	39.4
Relaxed limpet	4.7	7.9	9.3	9.6
