The IGFA world record is 24.32 kg (53 lb 10 oz) caught in Parismina Ranch, Costa Rica, by Rafael Montalvo.

[8] Within estuaries, juvenile common snook are most often found inhabiting areas such as coastal wetland ponds, island networks, and creeks.

[9] Despite being a euryhaline species of fish, the common snook shows a tendency to gravitate towards lower-salinity conditions in the early stages of its life.

[10] By being able to adapt and thrive in both high- and low-salinity conditions through osmoregulation, common snook display a high level of habitat plasticity.

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.

[16] A cold snap in January 2010 resulted in a 41.88% decline in nominal abundance of the common snook population in southwest Florida from the previous year and a 96–97% decrease in apparent survival estimates.

[17] C. undecimalis is widespread throughout the tropical waters of the western Atlantic Ocean, from the coast of the North Carolina to Brazil including the Gulf of Mexico and the Caribbean Sea.

[22] Over the past 15 years, snook have extended their range as far north as the Suwannee River Estuary (~29°N), where an exponential increase in their population has occurred.

[26] The IGFA all-tackle world record for common snook stands at 53 lb 10 oz (24.3 kg) caught by Gilbert Ponzi near Parismina Ranch, Costa Rica.

Previous world records were caught in Fort Myers, Florida, and Gatun Spillway Canal Zone, Panama.

[citation needed] "At the June 2012 Florida Fish and Wildlife Conservation Commission (FWC) meeting, Commissioners voted to keep the recreational harvest of snook in Gulf of Mexico waters closed through Aug. 31, 2013.

At the June 2013 FWC meeting, commissioners voted to let the recreational harvest of snook reopen in Gulf of Mexico waters from September 1 that year.
