Nearly 1/3 of the nation's [[manatee]] population lives here or migrates through the Lagoon seasonally. There was a mass death of manatees in 2021 due to the loss of seagrass, caused by leaks from septic systems and overuse of fertilizers.[{{Cite web |last=Jones |first=Benji |date=2022-02-08 |title=The manatees are starving |url=https://www.vox.com/down-to-earth/22917307/florida-manatees-algae-seagrass-indian-river-lagoon |access-date=2022-02-11 |website=Vox |language=en}}] |
