Even though the trained biologist’s eye could tell apart a dogfish and a seabass, they are superficially very similar. The remarkable consistency of the cuttlefishes’ responses suggests that they have access to clear clues that allow them to quickly and accurately distinguish between these groups.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://notexactlyrocketscience.wordpress.com/2007/12/22/cuttlefish-tailor-their-defences-to-their-predators/">Langridge’s study is further evidence that the intelligence of cuttlefish and their kin is a match for many back-boned animals.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://notexactlyrocketscience.wordpress.com/2007/12/22/cuttlefish-tailor-their-defences-to-their-predators/">Many of other cases of predator-specific signals come from the world of back-boned animals and I blogged about one such example earlier this year. <A href="http://notexactlyrocketscience.wordpress.com/2007/08/19/ground-squirrels-use-infrared-signals-to-fool-heat-seeking-rattlesnakes/">Ground squirrels pump hot blood into their tails<IMG class="linkscent-icon" src="http://notexactlyrocketscience.wordpress.com/favicon.ico" clueid="favIcon" /><IMG class="linkscent-icon" src="http://notexactlyrocketscience.wordpress.com/2007/12/22/cuttlefish-tailor-their-defences-to-their-predators/chrome://interclue/content/cluecore/skins/default/pixel.gif" clueid="clueIcon" /></A></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/D5E9EFFF-F3F3-4D15-980D-9A57ACECCE3E/blog/" title="blog or email this clip"><img src="http://content9.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
