- The source says

- The page saysand introduced onto nearly every continent
- The source says
Sliders have been introduced through pet releases onto nearly every continent.
- The page sayslargemouth bass avoid sliders because of their bright warning colors
- The source says
Britson concluded that largemouth bass, that rely almost solely on visual cues to hunt, avoid sliders because of bright warning colors found on their plastrons and skin.
Note: 'almost solely' qualifies bass hunting by sight; the body reports the study's conclusion, which the quote states - The page saysSex in a slider egg depends on the heat of its nest
- The source says
Determination of the sex of hatchlings in a nest is temperature-dependent.
- The page saysOmnivore
- The source says
As they mature, they experience an ontogenetic shift and become omnivores.
- The page saysan adult female's shell averages 25.4 cm against a male's 17.78 cm
- The source says
Average female shell length in adulthood is 25.4 cm. ... Average male shell length in adulthood is 17.78 cm.
- The page saysfemales can weigh up to 3,200 grams
- The source says
Females can reach a mass of up to 3,200 grams.
- The page saysBecause heat sets the sex
- The source says
Determination of the sex of hatchlings in a nest is temperature-dependent.
Note: 'Because' answers the FAQ's why-question; the quote states sex determination is temperature-dependent - The page saysBetween the two, a nest hatches mostly females with some males
- The source says
Nests that are above 28.6 degrees Celsius but below 29.6 degrees Celsius will have a high proportion of females, but males will be present.
- The page saysIn a pond slider's nest, heat sets the sex: below 28.6 degrees Celsius the eggs develop as all males, above 29.6 degrees all females
- The source says
Nests that are below 28.6 degrees Celsius develop as all males. Nests that are above 29.6 degrees Celsius develop as all females.

How the table was made: a writer drafted the profile from these sources and logged each claim with its quote, a reviewer with nothing but this table checked every sentence said no more than its quote, and a script confirmed each quote appears word for word in the source. The method is in the site'sAbout page.
