Lobsters are a common seafood delicacy, typically bluish-gray or red in color. Blue lobsters , however, are extremely rare. Due to their rarity and unique appearance, they are considered one of the most expensive lobsters in the world. So what kind of lobster is a blue lobster? Details are as follows:
1. Origin of Varieties
Blue lobsters generally refer to Florida blue lobsters, also known as "blue devil lobsters." They are a type of lobster with a blue shell due to genetic mutation and belong to the genus *Lobster* in the family Lobotomidae.
2. Geographical Distribution
Blue lobsters originated in Florida, USA, and are commonly known as Florida crayfish. They are a relatively ancient species of American crayfish. A few were later introduced to Germany, where they were bred. They were then introduced to Japan and Taiwan, where the aquarium industry is well-developed, and finally entered mainland China around 2004.
3. Morphological characteristics
Florida blue lobsters are relatively large, with a maximum weight of 500 grams. Compared to other lobster species, they have a more robust cephalothorax and a thicker exoskeleton. The claws of the Florida blue lobster are reddish-brown, while its body color ranges from olive green to dark blue.
4. Growth Habits
Florida blue lobsters are a type of freshwater lobster. They thrive in water temperatures between 20 and 28°C and typically live in waters 0.5 to 2.5 meters deep. They prefer clear, flowing water rich in food and feed mainly on tender grass roots, humus, and aquatic plankton.
5. Main Value
Blue lobsters were originally bred as ornamental shrimp. Because of their hardiness and resilience, and because they are less sensitive to water temperature than other ornamental crayfish, they are very suitable for beginners to raise.

With their rich lobster flavor and high nutritional value, they are highly favored by diners.
