The two-toed amphiuma (Amphiuma means) is an aquatic salamander widely distributed in the southeastern United States. It is commonly, but incorrectly, called "congo snake", "conger eel" or the "blind eel". Two-toed amphiumas are the most prominent in the Amphiumidae family and the longest salamander species in the United States, that can grow from 39 to 1,042 g (1.4 to 36.8 oz) in mass and from 34.8 to 116 cm (13.7 to 45.7 in) in length. They have four vestigial legs that end in two toes; the number of toes is one of the primary differences between Amphiuma means and its relatives, the one-toed and three-toed amphiumas. Additional genetic studies have been conducted on the three species; genetic distance estimates suggest that there is high levels of similarity between two-toed amphiumas and three-toed amphiumas, and much greater dissimilarity between the one-toed amphiuma and the two-toed amphiuma. The head is pointed and wedge-shaped, and the eyes are small. Adults retain a single gill slit on each side of the head. They are black, dark grey or dark brown in color. Two-toed amphiumas tend to be unicolored. Their dark dorsum contrasts with their slightly lighter ventrum... Wikipedia →

Possible
About 20% of wildlife watchers report a Two-toed Amphiuma sighting in Big Cypress National Preserve on a given day, based on 17 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 11th most-seen of the 12 amphibians we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
August and September
In those months about 30% of wildlife watchers report a Two-toed Amphiuma in Big Cypress National Preserve on a given day, against under 5% in April–May, July and November, the lowest months. Those are among Big Cypress National Preserve's wettest months, with about 220 mm of rain a month against 40 mm in March.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Two-toed Amphiuma sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
Only Big Cypress National Preserve, in our data
Big Cypress National Preserve is the only park on Wallace's Line with enough records to rate Two-toed Amphiuma sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Two-toed Amphiuma is recorded against all the amphibians logged in Big Cypress National Preserve (17 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
