Blue lobsters are a real phenomenon and can be cooked and enjoyed like any other type of lobster. They are typically found in two varieties: mutated regular lobsters and European blue lobsters. Mutated blue lobsters are the result of a genetic defect that causes the lobster to produce a certain protein in excess, making them bright blue instead of brownish-green or red. These lobsters are extremely rare, with odds of finding one being 1 in 2 million. European blue lobsters, on the other hand, have a cooler blue hue and are mostly found in the Mediterranean Sea and Black Sea. While they do turn red during the cooking process, they can still be cooked and served to impress. In terms of size, the Cobalt Blue Lobster, a type of crayfish, typically reaches about 5 inches within an aquarium environment.

The Australian Redclaw Crayfish is a species of Australian blue lobster
The Australian Redclaw Crayfish, or *Cherax quadricarinatus*, is a species of Australian blue lobster. This species is native to the tropical regions of Northern Australia and Southern New Guinea. While they are not as brightly coloured as the mutated American blue lobsters, they do exhibit a cool blue hue, particularly when cooked.
The Australian Redclaw Crayfish is a sought-after product due to its delicate crustacean flavour. They are non-aggressive and highly fertile, making them ideal for breeding in large numbers in captivity. Commercial farming of this species occurs in Queensland and the Northern Territory, with individuals harvested at between 35 and 130 grams.
This species is also the only species of crayfish that can be kept in indoor aquaria for ornamental use in the UK (excluding Scotland) without a licence. In the wild, they are found in tropical freshwater environments, typically inhabiting swamps, rivers, and billabongs.
The Australian Redclaw Crayfish is an important part of the ecosystem in these regions, serving as a food source for larger predators and contributing to nutrient cycling through their feeding and waste disposal behaviours. They are also culturally significant to the indigenous peoples of Australia, featuring in traditional stories and art.

They are native to North Australia and thrive in tropical freshwater environments
The Australian Redclaw Crayfish, often called "freshwater lobsters", are native to North Australia and thrive in tropical freshwater environments. They are the more common species of "yabby" in the Northern Territory and are found in most lakes and rivers in North Australia. They are also found in the state of Florida, but you must have a Florida Aquaculture License to own them.
The Redclaw Crayfish is a tropical freshwater crayfish that can grow to a large size comparable to a lobster. They are valued as a food source and as ornamental species. They are less aggressive than most crayfish and reproduce rapidly and easily, making them ideal for aquaculture and aquarium life. The ideal water temperature for Redclaw Crayfish is between 75˚ and 85˚ F, and they can withstand low oxygen levels.
In terms of their physical appearance, Redclaw Crayfish have exotic coloration and are sometimes referred to as Tropical Blue Crayfish or Blue Lobsters. They have a whitish background with large areas of bluish-black, and their antennae are pinkish with thick black spines.
It is important to note that true lobsters, belonging to the family Nephropidae, are saltwater creatures. While there are no true lobsters native to Australia, the country does have a diverse range of crayfish species, including the largest freshwater invertebrate in the world, the Tasmanian giant freshwater crayfish.

They are also known as Tropical Blue Crayfish and Queensland Redclaw
The Australian Blue Yabbie, also known as the Tropical Blue Crayfish or Queensland Redclaw, is a species of crayfish native to Australia and New Guinea. They are known for their bright blue coloration, which can vary from light blue to cobalt blue, with the intensity of the blue colour depending on the cleanliness of the water. These crayfish are also sometimes referred to as lobsters due to their large size, comparable to that of a lobster. They are considered a delicacy and are popular in both the culinary world and the aquarium trade.
In the wild, the Australian Blue Yabbie can reach appreciably larger sizes, but the selective breeding that produces their bright blue coloration limits their adult size. They typically reach about 5 inches within an aquarium environment, and their average market size is between 50 and 150 grams. However, they can reach up to 600 grams each. The larger Australian Redclaw Crayfish requires a tank that is at least 40 inches long and 20 inches deep, with at least 40 gallons of water.
The Queensland Redclaw is a tropical freshwater crayfish and is often kept as a pet in tropical aquariums due to its exotic coloration, ease of care, and rapid reproduction rate. They are less aggressive than most crayfish and can be housed with fish species and other invertebrates, although they will eat very small and slow fish. They are scavengers and will eat any leftover food, detritus, and waste at the bottom of the aquarium.
The ideal tank environment for the Queensland Redclaw consists of about 5 inches of aquarium sand or gravel on the bottom, with pipes, tunnels, decorative rocks, and caves. The water temperature should be between 75˚ and 85˚ F, and the pH should be maintained between 6.5 and 8. Regular partial water changes and filtration are also necessary to keep the aquarium clean and healthy for these crayfish.

They are valued as a food source and ornamental species
Australian blue lobsters are valued as a food source and ornamental species due to their rarity and unique appearance. They are a type of lobster that is characterised by their bright blue colour, which is caused by a genetic mutation resulting in the overproduction of a particular protein. The chances of encountering a blue lobster are estimated to be approximately one in two million, making them highly sought-after by both culinary enthusiasts and collectors.
As a food source, blue lobsters are considered a delicacy and are known to fetch high prices in restaurants. Some establishments have offered blue lobsters on their menus for upwards of $500, with one restaurant featuring a blue lobster and wagyu menu priced at $560. While the taste of blue lobsters is speculated to be sweeter than that of regular lobsters, it is generally agreed upon that cooking methods and proper seasoning play a more significant role in enhancing their flavour.
The rarity and visual appeal of blue lobsters also contribute to their value as ornamental species. Fishermen who catch these rare crustaceans often become famous, as the odds of finding a blue lobster are exceptionally low. Additionally, blue lobsters are often donated to aquariums, where they become attractions due to their unusual colouration. The likelihood of discovering a blue lobster in the wild or even in captivity is quite slim, making them a source of fascination for both experts and the general public.
The ornamental value of blue lobsters extends beyond their role in aquariums. Their unique colour has inspired the creation of rare Nike "Blue Lobster" sneakers, which can fetch several thousand dollars, further emphasising the demand for anything associated with these rare crustaceans. Additionally, there may be a collectors' market for blue lobsters, with prices fluctuating based on supply and demand dynamics.
While Australian blue lobsters are valued for their rarity and aesthetic appeal, their impact on the culinary world and the interest they generate among collectors and enthusiasts cannot be overlooked. The high prices commanded by blue lobsters in restaurants and the existence of a potential collectors' market underscore the multifaceted value of these rare crustaceans.
