<meta content="Escape responses of Australian scallops (Pecten fumatus and Chlamys asperrima) to native and introduced predatory seastars were compared in laboratory and field trials. The native seastar Coscinasterias muricata elicited an almost immediate escape response by scallops in all trials.
In contrast, there was a low frequency of escape response exhibited by scallops when held in contact
with the introduced seastar Asterias amurensis. These results are consistent with the hypothesis that
escape response in invertebrates has evolved relative to predation risk. The absence of predator
recognition in marine invertebrates may have serious implications for wild and farmed populations in
southern Australia where introduced predators are prevalent." name="eprints.abstract" />

The native seastar Coscinasterias muricata elicited an almost immediate escape response by scallops in all trials.
In contrast, there was a low frequency of escape response exhibited by scallops when held in contact
with the introduced seastar Asterias amurensis. These results are consistent with the hypothesis that
escape response in invertebrates has evolved relative to predation risk. The absence of predator
recognition in marine invertebrates may have serious implications for wild and farmed populations in
southern Australia where introduced predators are prevalent.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Additional Information:</th><td valign="top" class="ep_row">http://www.int-res.com/journals/meps/</td></tr><tr><th valign="top" class="ep_row">Keywords:</th><td valign="top" class="ep_row">Predator recognition · Escape response · Introduced species · Northern Pacific seastar</td></tr><tr><th valign="top" class="ep_row">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/270702.html">270000 Biological Sciences > 270700 Ecology and Evolution > 270702 Marine and Estuarine Ecology (incl.
