Editing Common snook (section)

===Physiological ecology===
Common snook, like many species of fish, are very in tune with their environments. Even a slight change in their surroundings can have a significant impact on their behavior. For example, common snook are able to determine when to start and stop spawning based on the temperature and salinity of the water they inhabit, the amount of rainfall in the area, and whether or not the moon is full.<ref name=Peters>{{cite journal|last1=Peters|first1=K.M.|last2=Matheson Jr.|first2=R.E.|last3=Taylor|first3=R.G.|title=Reproduction and early life history of common snook, Centropomus undecimalis (Bloch), in Florida|journal=Bulletin of Marine Science|date=1998|volume=62|issue=2|pages=509–529|url=http://docserver.ingentaconnect.com/deliver/connect/umrsmas/00074977/v62n2/s15.pdf?expires=1406518402&id=78767866&titleid=10983&accname=Guest+User&checksum=5D3BFB3208AF8C1FC4D577944D701AAC}}</ref><ref name="Aliaume">{{Cite journal |last=Aliaume |first=C. |last2=Zerbi |first2=A. |last3=Miller |first3=John M. |date=2005 |title=Juvenile snook species in Puerto Rico estuaries: distribution, abundance and habitat description |url=https://www.semanticscholar.org/paper/Juvenile-snook-species-in-Puerto-Rico-estuaries%3A-Aliaume-Zerbi/05b924fa4f8c8e3051adfb3791a563da69d47c26 |journal=Proc.

In some cases, disturbances in their environment can have very negative effects on the snook population. One example is the devastating results of a [[cold snap]]. Snook are very susceptible to cold temperatures, with the effects ranging from the complete halt of all feeding at a water temperature of {{convert|14.2|C|F}}, to the loss of [[Equilibrioception|equilibrium]] at {{convert|12.7|C|F}}, to death at a temperature of {{convert|12.5|C|F}}.<ref name="Shafland and Foote">{{Cite journal |last=Shafland |first=Paul L. |last2=Foote |first2=Karen Jo |date=1983-10-01 |title=A Lower Lethal Temperature for Fingerling Snook, Centropomus undecimalis |url=https://aquila.usm.edu/goms/vol6/iss2/12 |journal=Northeast Gulf Science |volume=6 |issue=2 |pages=175–177 |doi=10.18785/negs.0602.12 |issn=0148-9836}}</ref> A cold snap in January 2010 resulted in a 41.88% decline in nominal [[Abundance (ecology)|abundance]] of the common snook population in southwest Florida from the previous year and a 96–97% decrease in apparent survival estimates.<ref name="Adams 2012">{{cite journal|last1=Adams|first1=A.J.|last2=Hill|first2=J.E.|last3=Barbour|first3=A.B.|title=Effects of a severe cold event on the subtropical, estuarine-dependent common snook, Centropomus undecimalis|journal=Gulf and Caribbean Research|date=2012|volume=24|pages=13–21|doi=10.18785/gcr.2401.03|url=http://www.fishermanscoast.com/research/adams_et_al_GCR_2012_snook-cold-kill.pdf}}</ref>
