Pseudobatos prahli, also known by its common name Gorgona guitarfish is a species from the genus Pseudobatos. It is distinguished from other members of the genus by its coloration and rostral cartilages, and is native to the eastern Pacific Ocean.
The Gorgona Guitarfish is a benthic, coastal marine batoid (ray/skate) that has a body type similar to others in its genus; flattened with symmetric dorsal fins, a pointed snout, a long, asymmetrical tail with no lower lobe, and a triangular body. P. prahli can be distinguished from other guitarfishes by its distinct coloring and rostral cartilages. Its dorsal side is brown with white spots and speckles, darker brown splotches, and its ventral side is tan. The brown coloration appears during early stage embryonic development, with the dots only appearing in late stage development. The rostral cartilages are unique for being widely spaced and converging at the tip of the snout in a round shape [4]. This guitarfish is a medium-sized fish, but has a large size variation. Its minimum and maximum recorded weight is 540g and 2220g, respectively.
Typically the size range is from 50 cm TL to 90 cm TL, but the average size... Wikipedia →

No species of the same family or order lives in Machalilla National Park, so these are its closest relatives here: other sharks & rays.
Possible
About 30% of wildlife watchers report a Gorgona Guitarfish sighting in Machalilla National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Gorgona Guitarfish sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Machalilla National Park, in our data
Machalilla National Park is the only park on Wallace's Line with enough records to rate Gorgona Guitarfish sightings: about 30% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Gorgona Guitarfish is recorded against all the sharks and rays logged in Machalilla National Park (7 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.
