Underwater photos of California’s coast featured in books and magazines almost always showcase a certain fish: the garibaldi. Within the underwater kaleidoscope of California’s coastal waters, the Garibaldi fish stands out with its fiery orange hue. The garibaldi, a member of the damselfish family, is the California State marine fish, and its possession is illegal.
The fish is likely named after the 19th-century Italian revolutionary Giuseppe Garibaldi, whose army wore bright red shirts, or after the “garibaldi”, a woman’s red blouse worn in the 1890’s.
Biologically speaking, the Garibaldi fish owe their orange coloring mainly to pigments called carotenoids. These carotenoids are pretty interesting; you’ll find them in many fruits and vegetables, like carrots, for example, where they give off that familiar orange glow. Garibaldi eat a diet rich in crustaceans, such as crabs and shrimps, which are packed with these pigments. When the fish ingest them, the carotenoids are absorbed and deposited into the skin tissues.
Carotenoids can also act as antioxidants, which means they might even play a role in protecting the fish’s cells from damage. This is a bit of a two-for-one deal: not only do they get to look good, but they also get some potential health benefits as well.
Interestingly, there’s a bit of a territorial aspect to the bright orange coloration. Garibaldi fish are known to be quite territorial, and the males are especially flashy. They use their bright coloration to ward off rivals and also to attract mates.
The color isn’t just a superficial beauty mark; it plays a significant role in the fish’s survival and reproductive strategies. The orange hue signals strength, dominance, and overall fitness. It’s like a badge of honor they wear to proclaim, “Look at me, I’m strong, healthy, and in charge here!”
The Garibaldi is more than just a pretty face in the crowd. This fish, found from Monterey Bay down to Baja California, displays behaviors and characteristics that make it a subject of intrigue for marine biologists and diving enthusiasts alike.
One of the best places to see Garibaldi if you are a diver or enjoy snorkeling is off the coast of Catalina Island, about 20 miles from Long Beach. One particularly popular spot is Casino Point in the city of Avalon on the island.
Known for being highly territorial, the male Garibaldi is an underwater homeowner, meticulously crafting nests from red algae during mating season. This homemaking process is not just about building; it’s about showmanship. The males showcase their algae-laden nests to prospective females in an underwater dance, swimming around their creation with pride, hoping to entice the females to lay their eggs there.
But the courtship doesn’t end with the dance. Once the female is wooed and the eggs are laid, the male Garibaldi takes on the role of a nurturing parent. He stands guard over the eggs, fanning them with his pectoral fins to ensure they are well-oxygenated. He even goes to the extent of confronting divers or other fish that venture too close to his precious brood.
The Garibaldi’s territorial nature also extends to a curious interaction with humans. Despite their fierceness in protecting their domain, these fish are known to approach divers, examining them with an inquisitive gaze. This friendliness, coupled with their radiant color, makes them a favorite subject among underwater photographers.
“The only thing that seems to affect their fearless behavior is the color of the animal that’s approaching them,” said Cabrillo Marine Aquarium (CMA) Research Curator Dr. Kiersten Darrow. “They will attack everybody else, but if they see that it’s a garibaldi fish of a certain type then they will back away.”
Perhaps even more fascinating is the Garibaldi’s voice – a distinctive thumping sound that some divers have reported hearing. Though the exact reason for this sound is not entirely understood, it’s believed to be related to their territorial behavior, adding another layer to the mystique of this remarkable fish.
Beyond its engaging behaviors, the Garibaldi’s story carries a note of triumph in conservation. Its popularity led to overfishing in the past, which spurred protective measures. Today, the Garibaldi enjoys protected status in California waters, safeguarding it from harm and allowing it to thrive.
A testament to resilience, the Garibaldi can live for over 20 years, growing slowly and reaching full maturity at about six years of age. This longevity, coupled with its unique characteristics, makes it a symbol of the diverse and vibrant marine life that graces California’s coastline.
In the world of marine biology, where hidden wonders often lie beneath the waves, the Garibaldi emerges as a charismatic star. With its bold color, intricate courtship rituals, protective parenting, and friendly curiosity, it captures the imagination, not just as a beautiful spectacle but as a complex character in the grand tapestry of ocean life. Whether seen during a dive or behind the glass of an aquarium, the Garibaldi remains a fascinating glimpse into the rich and often surprising world beneath the sea.
