Hyastenus elatus is a species of crab in the family Epialtidae. [1] It is one of several decorator crabs, habitually covering itself in aposematic sponges which may also serve as camouflage.
There were several figures named Elatus or Élatos in Greek mythology.
Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting tail-like abdomen, usually hidden entirely under the thorax. They live in all the world's oceans, in freshwater, and on land. They are generally covered with a thick exoskeleton. They generally have five pairs of legs, and they have pincer claws on the ends of the frontmost pair. They first appeared during the Jurassic period, around 200 million years ago.
Hermit crabs are anomuran decapod crustaceans of the superfamily Paguroidea that have adapted to occupy empty scavenged mollusc shells to protect their fragile exoskeletons. There are over 800 species of hermit crab, most of which possess an asymmetric abdomen concealed by a snug-fitting shell. Hermit crabs' soft (non-calcified) abdominal exoskeleton means they must occupy shelter produced by other organisms or risk being defenseless.
Callinectes sapidus, the blue crab, Atlantic blue crab, or, regionally, the Maryland blue crab, is a species of crab native to the waters of the western Atlantic Ocean and the Gulf of Mexico, and introduced internationally.
The Japanese spider crab is a species of marine crab and is the biggest one that lives in the waters around Japan. At around 3.7 meters, it has the largest leg-span of any arthropod. The Japanese name for this species is taka-ashi-gani,, literally translating to “tall legs crab”. It goes through three main larval stages along with a prezoeal stage to grow to its great size.
Horseshoe crabs are arthropods of the family Limulidae and are the only surviving xiphosurans. Despite their name, they are not true crabs or even crustaceans. Rather, they are chelicerates. This makes them more closely related to arachnids like spiders, ticks, and scorpions. The body of a horseshoe crab is divided into three main parts: the cephalothorax, abdomen, and telson. The largest of these, the cephalothorax, houses most of the animal's eyes, limbs, and internal organs. It is also where the animal gets its name, as its shape somewhat resembles that of a horseshoe. Horseshoe crabs have changed little in appearance since they first evolved in the Triassic, earning them the title of "living fossil".
The Chinese mitten crab, also known as the Shanghai hairy crab, is a medium-sized burrowing crab that is named for its furry claws, which resemble mittens. It is native to rivers, estuaries and other coastal habitats of East Asia from Korea in the north to Fujian, China in the south. It has also been introduced to Europe and North America, where it is considered an invasive species. The species features on the list of invasive alien species of Union concern. This means that the import of the species and trade in the species is forbidden in the whole of the European Union.
Hibiscus elatus, synonym Talipariti elatum, known typically as the blue mahoe or majó azul, is a species of flowering tree in the mallow family, Malvaceae.
Portunus pelagicus, also known as the blue crab, blue swimmer crab, blue manna crab and flower crab is a species of large crab found in the Indo-Pacific, including off the coasts Indonesia, Malaysia, Cambodia, Thailand, the Philippines, and Vietnam; and in the intertidal estuaries around most of Australia and east to New Caledonia.
Podocarpus elatus, known as the plum pine, the brown pine, the Illawarra plum or the Queensland Christmas tree, is a species of Podocarpus endemic to the east coast of Australia, in eastern New South Wales and eastern Queensland.
The coconut crab is a terrestrial species of giant hermit crab, and is also known as the robber crab or palm thief. It is the largest terrestrial arthropod known, with a weight of up to 4.1 kg (9 lb). The distance from the tip of one leg to the tip of another can be as wide as 1 m. It is found on islands across the Indian and Pacific Oceans, as far east as the Gambier Islands, Pitcairn Islands and Caroline Island and as far west as Zanzibar. While its range broadly shadows the distribution of the coconut palm, the coconut crab has been extirpated from most areas with a significant human population such as mainland Australia and Madagascar.
Pisinae is a subfamily of crabs in the family Epialtidae, comprising the following genera:
Hyastenus bispinosus is a species of crab in the family Epialtidae, found around Ambon, the Banda Islands, Timor and the Lembeh Strait off Sulawesi.
Hyastenus is a genus of crabs in the family Epialtidae, subfamily Pisinae, containing the following extant species:
Lestes elatus is a species of damselfly in the family Lestidae, the spreadwings. It is known commonly as the emerald spreadwing. It is native to India, Thailand and Sri Lanka.
Hyastenus borradailei, sometimes called white-v hydroid spider crab, is a small crustacean belonging to the Epialtidae family. It is native to the Indo-Pacific.
John Robertson Henderson CIE FRSE FZS FLS was a Scottish zoologist who specialized in the taxonomy of marine crustaceans, particularly the decapods, and worked on specimens collected by the oceanic research vessels Investigator and Challenger. From 1892 until 1911 he was Professor of Zoology at Madras Christian College in India. From 1908 to 1920 he was Superintendent of the Government Museum in Madras. He also took an interest in numismatics and Indian history.
Hyastenus hilgendorfi is a species of spider crab from the family Epialtidae, classified in the sub-family Pisinae, from the Indo-Pacific region. It has been recorded in the Suez Canal and there have been a few records in the eastern Mediterranean, making it a Lessepsian migrant.
The wildlife of Christmas Island is composed of the flora and fauna of this isolated island in the tropical Indian Ocean. Christmas Island is the summit plateau of an underwater volcano. It is mostly clad in tropical rainforest and has karst, cliffs, wetlands, coasts and sea. It is a small island with a land area of 135 km2 (52 sq mi), 63% of which has been declared a National park. Most of the rainforest remains intact and supports a large range of endemic species of animals and plants.
The Christmas and Cocos Islands tropical forests ecoregion covers forested areas of Christmas Island and North Keeling Island, two small seamount islands south of the Indonesian island of Java. The forests of these two islands share tree species of the Indo-Pacific and Melanesian types on nearby islands, the forests of Christmas Island and North Keeling Island are unique in how they reflect the effects of large populations of terrestrial red crabs. Because of the remoteness of the islands, there are many endemic species.
