What’s the real story behind the unforgettable “Dory” from Finding Nemo? Let’s dive in and explore the reality of Dory fish.
Exploring the Iconic Blue Tang Fish
When we think of Dory, most of us picture the bubbly, forgetful character from the Disney-Pixar’s Finding Nemo and its sequel, Finding Dory. The real fish behind this character is the Blue Tang, scientifically known as Paracanthurus hepatus.
Dory Fish Characteristics
One of the most striking features of Dory fish is their bright blue colour. It serves as a natural camouflage in the deep blue sea, hiding them from predators.
Blue Tangs have a unique elongated body shape, with a length of up to 12 inches in adulthood. Look out for a black ‘palette’ design, which is the reason for its alternate name – the Palette Surgeonfish.
Interestingly, their tail fins aren’t just for show. They host a pair of spine-like structures, reminiscent of a surgeon’s scalpel. Hence the name, surgeonfish. They are also equipped with distinctive dorsal fins and sharp, retractable spines.
Habitat and Distribution
These fish inhabit the warmer parts of the Atlantic Ocean, especially the Caribbean and the Gulf of Mexico. Blue Tangs are synonymous with coral reef environments, adding a dash of colour to these underwater landscapes.
They’ve been spotted from New York all the way to Brazil, demonstrating a wide geographical range. Snorkelers and divers can observe them in various reef locales like the Great Barrier Reef and the Red Sea.
Blue Tang Fish Behaviour
Blue Tangs are social fish. They often swim in schools during the day, especially when they are juveniles. Did you know that Dory fish are algae grazers? They help keep coral reefs healthy by consuming excess algae.
Blue Tangs have a fascinating life cycle. They begin life as translucent larvae, gradually developing their iconic colour as they mature. They show notable migration patterns, usually associated with spawning events.
