Saddle Wrasse
thalassoma duperrey
The Saddle Wrasse (Thalassoma duperrey), known locally in Hawaii as hinalealauwili, is one of the most common and curious reef fish found in the Hawaiian archipelago. Extremely abundant in shallow coastal waters, these active, diurnal swimmers are famous for their bold, inquisitive nature. They often follow divers and snorkelers, hoping the disturbance will kick up tasty invertebrates from the sandy bottom or reef crevices. As protogynous hermaphrodites, their life history is a fascinating journey of transformation, transitioning from female to male when social structures demand. Their ubiquitous presence and playful behavior make them an absolute favorite for marine life observers in Hawaiian waters.
生息地: Found in shallow coral reefs, rocky shorelines, and sandy-bottomed lagoons throughout the Hawaiian Islands.
外見
Easily recognized by their vibrant, multicolored bodies, adult Saddle Wrasses feature a deep blue-green head, a prominent bright orange-red vertical band (or 'saddle') just behind the gill covers, and a greenish-blue body. Their tail fin is lyre-shaped, particularly in terminal phase males. Juveniles look strikingly different, displaying a horizontal dark stripe along a pale body, which helps them blend in. They grow to a maximum length of about 25 centimeters.

おもしろい事実
If the dominant male in a social group dies, the largest female will begin changing color and behavior to take his place within hours, fully transitioning into a fertile male in a matter of weeks.
The Hawaiian name for this fish is hinalealauwili, which refers to its erratic, twisting swimming pattern around the reef.
They are so bold and inquisitive that snorkelers often find themselves surrounded by them just by gently kicking sand with their fins.
特殊能力
Sequential Hermaphroditism
They begin life as females and can transition into colorful terminal males when the dominant male of a harem dies.
Inquisitive Foraging
They actively follow larger marine animals or human divers to feed on small organisms exposed by disturbed substrate.
Pectoral Fin Propulsion
They use their pectoral fins in a wing-like flapping motion to maneuver agilely around complex coral structures.
