Lobsters are marine animals that live in cold oceans and seas. There are two species of true lobsters: the European or Breton lobster, found all around Europe, and the American lobster, found on the Atlantic coast of North America. However, there are several species of Australian lobsters, which are not true lobsters but belong to the family Palinuridae. These include the Eastern Rock Lobster, the largest spiny lobster in the world, and the Western Rock Lobster, found in southern Western Australia. Rock lobsters, or spiny lobsters, are often called sea crayfish or crays, and are found in tropical areas like coral reefs and rocky crevices in the Pacific, Atlantic, and Indian Oceans. Australia also has a diverse range of crayfish species, including the largest freshwater invertebrate in the world, the Tasmanian giant freshwater crayfish.

What You'll Learn
Rock lobsters are found in Australia
Rock lobsters, also known as spiny lobsters, are found in Australia. They are sometimes brown, red, or very colourful and live in coral reefs and in crevices of rocks in tropical areas. Rock lobsters occur in the hot waters of the Pacific, Atlantic, and Indian Oceans, as well as in the Red and Mediterranean Seas.
In Australia, the Southern Rock Lobster is found in the southeast, while the Western Rock Lobster is found in the south and west of the country. The Western Rock Lobster, or Panulirus cygnus, is the basis of Australia's most valuable fishery, contributing 20% of the value of the country's fishing industry. The species was first described in 1962, and is found along the western coastline of Australia, from Hamelin Bay to the North West Cape, as well as islands such as the Houtman Abrolhos and Rottnest Island. The larvae of the species develop in the meadows of seagrasses of Western Australia, migrating towards the deeper ocean and coral reefs.
The Southern Rock Lobster is the largest spiny lobster in the world and can grow to over 15 kg. The largest recorded specimen of the Western Rock Lobster is 5.5 kg, but a maximum weight of 5 kg is considered typical. The average accepted form of measurement, that of the carapace, is from 80 to 100 millimetres in length.
Slipper lobsters, which are more closely related to rock lobsters than "true" lobsters, are also found in Australia. They are known as "bugs" in the country.

True lobsters are not found in Australia
Rock lobsters in Australia include the Eastern Rock Lobster, which is the largest spiny lobster in the world and can grow to over 15 kg. It is found in New South Wales, Victoria, South Australia, Tasmania, and New Zealand waters. Another species is the Western Rock Lobster, found in southern Western Australia, which can grow up to 5.5 kg. The Western Rock Lobster is the basis of Australia's most valuable fishery, making up 20% of the value of the country's fishing industry.
Crayfish, also known as "freshwater lobsters," have a similar appearance to true lobsters with their large front claws. However, their bodies are smoother, and they have longer legs. There are several different species of crayfish in Australia, including yabbies, red claws, marron, koonacs, and the endangered giant crayfish in Tasmania, which can grow to over 5 kg in size.
Other lobster-like creatures found in Australia include scampi, also known as Dublin Bay prawns or langoustines, which are rare and expensive in the country. Additionally, there are "bugs," which are marine animals also known as flathead lobsters or slipper lobsters, and blind lobsters, which are eyeless and found in the Western Australian Museum crustacean collection.

Lobster-like creatures such as scampi are found in Australia
Australia is home to a variety of unique marine creatures, including some that resemble lobsters. While the "true" lobsters, which belong to the genus Homarus, are not found on the Australian coastline, there are other lobster-like creatures that inhabit the country's waters. One such creature is the scampi, which is also known as the Norwegian Lobster or Dublin Bay Prawn. Scampi belong to the family Nephropidae, the same family as "true" lobsters. They are found in deep waters off the west coast of Australia, particularly near Port Hedland. Scampi are a benthic species, inhabiting the continental shelf at depths of 420-500 meters. They are managed under the North West Slope Trawl Fishery, which implements sustainable fishing practices to maintain the population.
In addition to scampi, there are other lobster-like creatures found in Australia, including rock lobsters and crayfish. Rock lobsters, also known as spiny lobsters, are found in tropical areas and can be brown, red, or very colourful. In Australia, the Southern Rock Lobster is found in south-eastern regions, while the Western Rock Lobster, or Panulirus cygnus, is found off the west coast. This species is the basis of Australia's most valuable fishery, contributing significantly to the country's fishing industry. Crayfish, on the other hand, are freshwater crustaceans that inhabit rivers, lakes, and streams. Australia is home to the largest freshwater invertebrate in the world, the Tasmanian giant freshwater crayfish, which is endemic to Tasmania.
It is worth noting that the term "lobster" is also sometimes used to refer to other crustaceans in Australia, such as the Lord Howe Island Phasmid or Land Lobster (Dryococelus australis), which may be the rarest insect in the world. Additionally, the term "scampi" can have different meanings in different parts of the world. In South Asia, for example, Macrobrachium rosenbergii is often referred to as freshwater scampi.
Overall, while the traditional lobsters of the genus Homarus are not found in Australia, the country is home to a diverse range of lobster-like creatures, including scampi, rock lobsters, and crayfish, each with their own unique characteristics and ecological significance. These creatures play an important role in Australia's marine ecosystem and contribute to the country's cultural and economic landscape, particularly in the fishing industry.

Bugs, a type of crustacean, are found in Australia
While lobsters are not typically referred to as bugs, the term ""bug"" is often used colloquially to refer to any creepy-crawly arthropod. With this understanding, lobsters can be considered bugs, and they are found in Australia.
The Australian Museum recognises the Eastern Rock Lobster as the largest spiny lobster in the world, sometimes growing to over 15 kg. The Southern Rock Lobster is found in southeastern Australia, while the Western Rock Lobster is found in southern Western Australia.
Australia is also home to a diverse range of other unique bugs and insects. For example, the Loboscelidia wasp, native to the country, has horns and looks like it has "escaped some hellish nest." The Australian walking stick is another insect that is so unusual-looking that it "screams 'I don't exist.'"
Australia also boasts a wide variety of ants, with over 1,200 known species in the country and over 15,000 worldwide. Ants can be found in almost every environment, from rainforests to arid deserts and even underwater. The Blue Ant, found in Tasmania, New South Wales, South Australia, and Victoria, is a particularly distinctive species, growing up to 2.5 cm long.
In addition to its abundance of ants, Australia is home to other fascinating insects, including the Australian Painted Lady butterfly, which migrates from place to place, and the Australian earthworm, which can grow to an average length of one meter.

Crayfish, or freshwater lobsters, are found in Australia
Australia is home to the largest freshwater invertebrate in the world, the Tasmanian giant freshwater crayfish (*Astacopsis gouldi*). This species is native to Tasmania and is listed as endangered due to overfishing and human activity destroying its habitat. In the past, it was possible to find specimens weighing up to 5 kg in the northern rivers of Tasmania, but today, specimens over 2 kg are rare.
Other species of crayfish in Australia include the marron, a native freshwater crayfish species from south-western Australia that is cultivated in dams and has a small aquaculture industry built around it. Marron is considered sweeter than other crayfish and is preferred by some people. Another species found in Australia is the yabby, which is found in freshwater rivers and dams and is similar to a prawn (shrimp) but with large nippers.
Rock lobsters, also known as spiny lobsters, are sometimes mistaken for crayfish in Australia, New Zealand, and South Africa. However, they are not the same. Spiny lobsters are found in the Pacific, Atlantic, and Indian Oceans, as well as in the Red and Mediterranean Seas. They live in coral reefs and crevices of rocks in tropical areas and can be brown, red, or very colourful. In Australia, the Southern Rock Lobster is found in south-eastern Australia, while the Western Rock Lobster is found in southern Western Australia.
