Fact Check: "The American alligator can grow up to 19 feet long."
What We Know
The American alligator, scientifically known as Alligator mississippiensis, is a large reptile native to the southeastern United States. According to the South Carolina Department of Natural Resources, the largest recorded alligator measured 5.8 meters (19 feet 2 inches) in length, and weighed approximately 473 kilograms (1,043 lbs), although such sizes are rare (SCDNR). Similarly, the Nonindigenous Aquatic Species database confirms that the maximum recorded length for this species is 5.84 meters (19 feet 2 inches) (American alligator (Alligator mississippiensis) - Species Profile). Furthermore, a Wikipedia entry also corroborates this record, noting that the largest alligator was killed in 1890 and measured 5.84 meters (19 feet 2 inches) (Wikipedia).
Analysis
The claim that the American alligator can grow up to 19 feet long is substantiated by multiple credible sources. The South Carolina Department of Natural Resources, a reputable state agency, provides a detailed account of the species, including the record size of 19 feet 2 inches. This source is reliable as it is based on scientific observations and records maintained by wildlife authorities.
The Nonindigenous Aquatic Species database is another authoritative source that lists the maximum length of the American alligator as 5.84 meters. This database is maintained by the U.S. Geological Survey, which adds to its credibility. Wikipedia, while generally a good starting point for information, is less reliable due to its open-editing nature; however, it cites the same record from a historical perspective, which aligns with the other sources.
The consistency across these sources indicates that the claim is not only plausible but also supported by documented evidence. It is important to note, however, that while the maximum recorded length is 19 feet, such sizes are uncommon in the wild, and most adult alligators are significantly smaller.
Conclusion
Verdict: True
The claim that the American alligator can grow up to 19 feet long is true, as it is supported by multiple credible sources, including wildlife agencies and scientific databases. The record size of 19 feet 2 inches is recognized and documented, although such sizes are rare in the wild.
