From: Seahorses in focus: local ecological knowledge of seahorse-watching operators in a tropical estuary

Aspect Number of different responses Consensual responses C.I. Fidelity level (%) Correspondence with scientific data
Taxonomy
 No. of species 4 One species: Longsnout
(H. Reidi)
20 62.5 Yes [20]
 Classification criteria 2 Body shape (not coloration) 31 97 Yes [24]
Distribution
 Habitat 1 Mangrove and reef 32 100 Yes [20]
 Vertical distribution 3 No specific depth. (daily intense tidal depth variations in the estuary) 26 81 Yes [2]
 Occurrence determinant 1 Determined by the presence of mangrove roots as anchoring points and shelter 32 100 Yes [30]
 Exposition to water currents 2 Preferentially inhabit backwater areas protected from strong currents 31 97 Yes [3, 30]
 Salinity 1 In the mangrove, are abundant in sites with high salinity levels 32 100 Yes [3, 35]
 Water transparency 1 Abundant in high transparency level conditions 32 100 No data
 Seasonal abundance 2 Abundant in summer (dry season), scarce in winter (wet season). 31 97 Yes [3]
 Migration period 2 Rainy season, in winter (May to September) 32 100 Yes [3]
 Reason for migration 2 To avoid low salinity levels caused by the rainy season’s freshwater input. Also are removed out of the mangrove to the sea by floods and currents 32 100 Yes [3]
 Anchoring points 6 Mangrove roots 32 100 Yes [30, 33, 44]
Trophic ecology

 Predators 10 Crabs and fishes 32 100 Yes [3, 40, 44]
 Is camouflage related to color shift? 2 Yes. Is capable of changing its own color 30 94 Yes [24]
Reproduction
 Sexual dimorphism 1 Brooding pouch present on males 32 100 Yes [25]
 Reproductive behavior 2 Contraction to give birth, releasing neonates as a “dust cloud”. 20 62.5 Yes [45]
 Brood size 3 500 to 1000 newborns 29 91 Yes [2]
 Survival rate 3 Up to 15 % 29 91 Yes [24]
 Reproductive period 1 Throughout the year 32 100 Yes [3, 20, 33]
