A phyllosoma larva of the spiny lobster Palinurus elephas, from Ernst Haeckel's Kunstformen der Natur. The larvae of the Achelata (slipper lobsters, spiny lobsters and furry lobsters) are unlike any other crustacean larvae. The larvae are known as phyllosoma, after the genus Phyllosoma erected by William Elford Leach in 1817. They are flattened ...
A new critter is creeping into the United States' waters. The invasive Australian redclaw crayfish has been spotted in southern Texas, roughly 8,000 miles from its home. The freshwater crustacean ...
The adult forms have never been recognized, and the group is known only from its larvae, the "y-nauplius" and "y-cyprid" larvae. [2] The only known genus is Hansenocaris and the family Hansenocarididae. They are mostly found in the north Atlantic Ocean, neritic waters around Japan, [3] and the Mediterranean Basin, where they also survive in ...
Emerita is a small genus of decapod crustaceans, [3] known as mole crabs, sand fiddlers, sand fleas or sand crabs. These small animals burrow in the sand in the swash zone and use their antennae for filter feeding. [4] [5]
Crustaceans (from Latin meaning: "those with shells" or "crusted ones") are invertebrate animals that constitute one group of arthropods that are traditionally a part of the proposed subphylum Crustacea (/ k r ə ˈ s t eɪ ʃ ə /), a large, diverse group of mainly aquatic arthropods including decapods (shrimps, prawns, crabs, lobsters and crayfish), seed shrimp, branchiopods, fish lice ...
Copepods (/ ˈ k oʊ p ə p ɒ d /; meaning "oar-feet") are a group of small crustaceans found in nearly every freshwater and saltwater habitat.Some species are planktonic (living in the water column), some are benthic (living on the sediments), several species have parasitic phases, and some continental species may live in limnoterrestrial habitats and other wet terrestrial places, such as ...
Scientists discovered a 520-million-year-old fossilized larva with brains and guts intact, offering unprecedented insights into early arthropod evolution. ... With the exception of those found in ...
Emerita analoga, the Pacific sand crab, Pacific mole crab or coldwater mole crab, is a species of small, sand-burrowing decapod crustacean found living in the sand along the temperate western coasts of North and South America. It is found on exposed sandy beaches in the swash region of the intertidal zone.
