Seahorses in laboratory and field displaying biofluorescence.
Hippocampus reidi exhibiting biofluorescence in green and red spectrum in laboratory (A) and field (B) conditions. Male seahorses of 101 mm (A) shows dots of green biofluorescence in the trunk and head areas, while male seahorse (B) 123 mm, shows stripes of green biofluorescence in the trunk and head areas. Biofluorescence lighting in green spectrum in the eyes in laboratory (C) and field (D) conditions. Two-day-old seahorses showing no biofluorescence (E,F). A young seahorse, 4.3cm, exhibits mostly red biofluorescence under exciting light (G). The same individual is depicted in orange under natural white light (H). Photos: AAB.
