everything about the hairy blenny
who is the hairy blenny
A small, sturdy fish of the family Labrisomidae, from rocky shores and gravel bottoms with algae, reefs and seagrass beds, between the surface and 5 m. It reaches 23 cm and is the largest labrisomid in the Caribbean. It almost always stays on the bottom, hidden in holes and crevices, and quickly flees to another hiding place when disturbed. It feeds on crustaceans, snails, sea urchins, ophiuroids (brittle stars), polychaete worms and other fish. It breeds in territories on the bottom, and the males guard the eggs. It has little commercial use and is sold for aquariums.
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 hairy blenny.
identification
A sturdy body, with a pointed or slightly rounded snout, and a diagonal row of fleshy cirri on the back of the head. It has four irregular dark brown bands, a black spot with a pale edge on the gill cover and often a dark spot in front of the dorsal fin. Adult males have red on the underside of the head, chest and belly. Because it lives in holes and crevices, it is usually seen only up close.
where found
It lives on shallow rocky shores of the Caribbean, Central America and northern South America, as far as Brazil, where it ranges from Ceará to Santa Catarina. It also occurs in the eastern Atlantic, from Madeira and the Canaries to the west coast of Africa.
Habitat: Rocky shores, gravel bottoms with algae, reefs and seagrass beds, between the surface and 5 m.

best time of day
Daytime. A daytime species, living on the bottom and usually hiding in holes and crevices.
rules for the hairy blenny
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 has spines in the dorsal fin, but is not dangerous. Since it hides, it is rarely hooked; if it comes on the line, release it quickly.
how much it weighs without taking it out of the water
Length-weight relationship W = a·Lb (a = 0.00933, b = 3.12; 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:
