Live Poll

Should the state restrict lead-based ammunition for controlling invasive species to protect local wildlife?

In November 2023, a 7-foot female American crocodile died in Florida due to lead poisoning. A necropsy discovered 22 grams of lead, including 23 air rifle pellets, in the animal's stomach.

Why it matters

The crocodile died after scavenging green iguana carcasses that had been shot with lead ammunition. This incident highlights the unintended ecological consequences of controlling invasive species with lead, as predators consume the toxic remains.

The necropsy recovered 23 air rifle pellets and one fishing weight from the animal's stomach. The 7-foot crocodile also exhibited significant health markers including tooth loss and black stains in the mouth.

In November 2023, a 7-foot female American crocodile was captured and died.

Culture Shift

This event highlights the unintended ecological consequences of the state's invasive species management policies. The incident marks a departure from traditional predator management by showing how local wildlife interacts with common pest control methods.

Residents should be aware that disposing of carcasses containing lead ammunition may affect local predatory wildlife. This case serves as a reminder to consider the environmental impact of pest control methods used in residential areas.

The takeaway

This case serves as the first documented instance of an American crocodile dying from lead poisoning in the state. Wildlife experts are now conducting further sampling to determine how widespread lead ingestion is among Florida crocodile and alligator populations.
