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 →

Rare
Under 5% of wildlife watchers report a Two-toed Amphiuma sighting in Orlando on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 9th most-seen of the 10 amphibians we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January–February and July
In those months about 10% of wildlife watchers report a Two-toed Amphiuma in Orlando on a given day, against under 5% in March–June and August–December, the lowest months.
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 Orlando, in our data
Orlando is the only city on Wallace's Line with enough records to rate Two-toed Amphiuma sightings: under 5% 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 Orlando (6 verified sightings), 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.
