everything about the pelican flounder
who is the pelican flounder
The pelican flounder belongs to the family Bothidae (lefteye flounders) and reaches 40 cm. It has a flexible body and an extremely large mouth, with the maxilla not reaching past the tip of the snout. It lives on the deep shelf and the slope, on sand, mud and clay bottoms, down to nearly 1,000 m. It feeds on large bottom animals. It occurs in Brazil and other countries of the region, from the Caribbean to the Guianas, and is caught by commercial fishing.
Essential profile. Identification, where it occurs and rules, with data from FishBase and the cited regulations. Season, time of day, technique and bait are added once we have a good source for the pelican flounder; in the meantime, see the similar species.
fun facts
- The body is flexible, and the maxilla does not extend past the tip of the snout, even with the huge mouth.
identification
A flat, flexible, short-bodied flounder with a huge mouth, its most striking trait. The tip of the lower jaw sits slightly beyond the upper one, and it has no canine teeth. It lives on deeper bottoms than other flounders in the region, such as Bothus ocellatus, and the very large mouth helps set this species apart.
where found
In Latin America it occurs in Colombia, Venezuela, the Guianas, Trinidad and Tobago and Brazil, on sand, mud and clay bottoms, from the shelf to the slope.
Habitat: Sand, mud and clay bottoms of the deep shelf, down to nearly 1,000 m.

rules for the pelican flounder
Summary of the regulations we found, with the source for each. Rules change; before keeping or transporting fish, check with the state environmental agency.
Conservation: Not on the Brazilian national list (Ministerial Ordinance GM/MMA No. 1.667/2026).
We found no species-specific rule beyond the region's general rules.
catch and release
catch and release Releasing the fish alive, quickly and with a wet hand. During a closed season it isn't always allowed: what the regulation says applies.
It is not dangerous to anglers. Since it comes from deep bottoms, it suffers barotrauma; release it carefully and quickly.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00513, b = 3.06; FishBase (relação peso-comprimento bayesiana, estimativa da própria espécie)). It's an average: a fat or lean fish can vary by 10% to 20%.

sources and references
Essential profile: size, length-weight, depth, countries and conservation come from FishBase and the cited regulations, and the texts were written from those sources. Season, time of day, sensitivities, technique and baits and lures are not included yet, because we did not find a good source for this species.

where each number comes from
The weather comes from three independent global models, cross-checked hour by hour: when they agree, confidence goes up; when they diverge, the band between them shows on the chart. Beyond 16 days, we use the GEFS ensemble of 31 simulations: if 20 of the 31 predict rain, the chance of rain is 65%. Sun and moon are calculated astronomically, with no uncertainty.
The index adds up, weighted for each species: time of day (species curve anchored to real sunrise and sunset), moon (transits, rise and set, phase), pressure (3 h trend and 24 h swing), water temperature (in rivers, estimated from air temperature; at sea, estimated by an ocean model), wind, rain, clouds, tide and the month in the species' cycle.

how accurate the forecast is
Accuracy measured in the reference project (4 regions, 93 days, forecast vs. observed): maximum temperature is off by 0.6 °C on average the next day and 1.7 °C at 7 days; rain of 5 mm or more is detected 76% of the time the next day and 57% at 7 days. Detection isn't everything: the false alarm rate isn't published here yet, and 93 days in 4 regions is still a small sample. We now also measure every day, at the app's destinations:
