Commonly referred to as the inland crab or tropical freshwater crab, this hardy species is well known for its ability to survive in harsh, dry environments and is the most widely distributed member of its genus.\u003c\/p\u003e\n\u003ch2 data-section-id=\"1hnfsvs\" data-start=\"562\" data-end=\"576\"\u003eAppearance\u003c\/h2\u003e\n\u003cp data-start=\"578\" data-end=\"923\"\u003eThese crabs typically display earthy tones such as brown, grey, maroon, or reddish shades that help them blend into their natural surroundings. Adults usually grow to around 5 cm across the shell. Like other freshwater crabs, they have a rounded carapace, four pairs of walking legs, and two claws, with one claw generally larger than the other.\u003c\/p\u003e\n\u003ch2 data-section-id=\"w8xrnd\" data-start=\"925\" data-end=\"951\"\u003eDistribution \u0026amp; Habitat\u003c\/h2\u003e\n\u003cp data-start=\"953\" data-end=\"1221\"\u003eInland freshwater crabs are found across much of northern and central Australia. Their range extends throughout Queensland and the Northern Territory, with smaller populations occurring in parts of Western Australia, South Australia, and north-western New South Wales.\u003c\/p\u003e\n\u003cp data-start=\"1223\" data-end=\"1385\"\u003eThey inhabit temporary waterways such as creeks, rivers, floodplains, and waterholes, including regions that experience long dry periods and extreme temperatures.\u003c\/p\u003e\n\u003ch2 data-section-id=\"16of5fg\" data-start=\"1387\" data-end=\"1420\"\u003eAdaptations to Dry Conditions\u003c\/h2\u003e\n\u003cp data-start=\"1422\" data-end=\"1770\"\u003eOne of the most remarkable traits of this species is its ability to survive drought through a process known as aestivation. During dry seasons, the crab digs deep burrows into mud or clay banks, often reaching depths of 50–100 cm. These burrows help retain moisture and protect the crab from dehydration until rainfall returns and waterways refill.\u003c\/p\u003e\n\u003cp data-start=\"1772\" data-end=\"1921\"\u003eThe entrance to the burrow is sealed with a plug of mud, creating a humid chamber underground where the crab can remain dormant for extended periods.\u003c\/p\u003e\n\u003ch2 data-section-id=\"1v5iars\" data-start=\"1923\" data-end=\"1947\"\u003eAmphibious Lifestyle\u003c\/h2\u003e\n\u003cp data-start=\"1949\" data-end=\"2256\"\u003eThe inland crab is semi-amphibious and can survive both in water and on land. Its modified gills are capable of functioning similarly to lungs when exposed to air. This adaptation allows the crab to leave shallow pools if water conditions become unsuitable, such as during low oxygen levels or extreme heat.\u003c\/p\u003e\n\u003cp data-start=\"2258\" data-end=\"2352\"\u003eOut of water, they often shelter beneath leaf litter, roots, or debris to stay cool and moist.\u003c\/p\u003e\n\u003ch2 data-section-id=\"ynen8a\" data-start=\"2354\" data-end=\"2362\"\u003eDiet\u003c\/h2\u003e\n\u003cp data-start=\"2364\" data-end=\"2589\"\u003eThese crabs are omnivorous scavengers. They primarily feed on algae and plant material that flourish after seasonal rains, but they will also consume decaying organic matter, insects, and small aquatic animals when available.\u003c\/p\u003e\n\u003ch2 data-section-id=\"1ur3dua\" data-start=\"2591\" data-end=\"2607\"\u003eReproduction\u003c\/h2\u003e\n\u003cp data-start=\"2609\" data-end=\"2795\"\u003eFemale inland freshwater crabs carry their fertilised eggs beneath their abdomen until the young have developed into juvenile crabs. A single female may produce between 100 and 350 eggs.\u003c\/p\u003e\n\u003cp data-start=\"2797\" data-end=\"3009\"\u003eThe young remain protected by the mother during development and are often released after the wet season begins, giving them the best possible chance of survival as waterways refill and food becomes more abundant.\u003c\/p\u003e","brand":"Aquaristic Online","offers":[{"title":"Default Title","offer_id":46044586868970,"sku":"19939","price":25.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0854\/0866\/files\/Freshwater-Crab.jpg?v=1779182849"}],"url":"https:\/\/www.aquaristiconline.com.au\/collections\/invertebrates-miscellaneous.oembed","provider":"Aquaristic Online","version":"1.0","type":"link"}
