'Squiggly wiggly' fossils rise from a Jurassic sea 2021-07-21T04:00:00Z These are the only echinoderms that demonstrate “functional” bilateral symmetry as adults, because the uniquely extended oral-aboral axis compels the animal to lie horizontally rather than stand vertically. Fundamentals of Biology 2015-01-01T00:00:00Z Along with sea urchins and starfish, sea cucumbers belong to a group called echinoderms. Why Smuggling of This Ocean Creature May Skyrocket 2017-06-02T04:00:00Z This group includes vertebrates - fish, amphibians, reptiles, birds and mammals including people - as well as animals called echinoderms including starfish and sea urchins and obscure creatures called hemichordates including acorn worms. Your oldest ancestor was really weird and had a big mouth 2017-01-30T05:00:00Z On a Friday in September, three of teacher Michael Knight’s classes got the chance to see, touch and study - but not eat - some of the echinoderms. Echinoderm Academy 2016-10-01T04:00:00Z The leathery echinoderms only emerge from their hiding-places in the dark. Silver in the deep 2016-03-31T04:00:00Z In echinoderms like sea stars, every arm bears two rows of tube feet on the oral side. Fundamentals of Biology 2015-01-01T00:00:00Z Congresswoman Pingree, whose past voting record falls firmly on the side of environmental and wildlife protections, is an unlikely champion for an exemption to echinoderm inspections. Why Smuggling of This Ocean Creature May Skyrocket 2017-06-02T04:00:00Z Because, of course, sea stars are echinoderms, not fish. In search of the starfish killer: The quest to save the original keystone species 2014-11-18T05:00:00Z Some existing echinoderms, such as brittle stars, are covered in crystal calcite microlenses that are sensitive to light. Palaeontology: Ancient starfish spotted predators 2014-04-04T13:51:04.774Z Thus, it looks like acorn worms, echinoderms, and chordates all shared a common ancestor. What Lives at the Bottom of the Mariana Trench? More Than You Might Think 2013-04-15T00:15:05.547Z Most of the main groups of the animal kingdom—arthropods, brachiopods, coelenterates, echinoderms, molluscs and even chordates, the branch from which vertebrates went on to develop—are found in the fossil beds of the Cambrian. The Cambrian explosion: Kingdom come 2013-03-21T16:02:17Z Jamie Pang, with the Center for Biological Diversity, was among those who tried to stop the echinoderm exemption last year. Why Smuggling of This Ocean Creature May Skyrocket 2017-06-02T04:00:00Z Gregory in 1906 After graduation he found work at the British Museum for Natural History, where he worked on the collections of rocks, fossil echinoderms and corals. Travels & Troubles in Geology: Africa 2012-07-16T14:15:10.627Z My initial interest in this project was spurred by a conversation with my friend Gordon Hendler, curator of echinoderms at the Natural History Museum of Los Angeles. USC Dornsife Scientific Diving: "Think Like a Brittle Star" 2012-06-18T13:45:00.380Z Sea cucumbers are echinoderms like sea stars, and they specialize in roving the abyssal plains of the world, harvesting food from the sediment with their feeding appendages. What Lives at the Bottom of the Mariana Trench? More Than You Might Think 2013-04-15T00:15:05.547Z How do you motivate an echinoderm to move when you want it to? 5-Armed Brittle Stars Always Face Front [Video] 2012-05-10T17:45:00.197Z "These roots oddly resemble echinoderms," said Doctor Lane, looking at the roots of the Eremurus. The Vanity Girl 2012-04-12T02:00:26.883Z Of or pertaining to ambulacra; avenuelike; as, the ambulacral ossicles, plates, spines, and suckers of echinoderms. Webster's Unabridged Dictionary 2012-03-24T02:00:23.513Z Pluteus, a free-swimming larval stage in the development of echinoderms, 54. The Biological Problem of To-day Preformation Or Epigenesis? The Basis of a Theory of Organic Development 2011-08-29T02:01:04.170Z You may know that echinoderms — like sea stars, sea cucumbers, and sea pigs — are the group of animals most closely related to our own group, the chordates, animals with a dorsal nerve cord. What Lives at the Bottom of the Mariana Trench? More Than You Might Think 2013-04-15T00:15:05.547Z We might find them slow, but for echinoderms—a group that includes sea urchins and sand dollars—brittle stars are pretty quick. 5-Armed Brittle Stars Always Face Front [Video] 2012-05-10T17:45:00.197Z Rich Mooi, curator of invertebrate zoology and geology at the California Academy of Sciences, writes about his expedition to the Philippines, where he surveyed echinoderms off the coast of Luzon Island. Scientist at Work: Chasing Down Sea Lilies 2011-07-08T21:14:54Z Rich Mooi, curator of invertebrate zoology and geology at the California Academy of Sciences, writes from the Philippines, where he is surveying echinoderms off the coast of Luzon Island. Scientist at Work: Exploring Biodiversity in the Philippines 2011-05-25T21:52:32Z And the reasons why he does become a man, rather than an echinoderm, or a fish, or a monkey, is only some slightly modifying circumstance, as, for instance, a longer gestation. The Religion of Geology and Its Connected Sciences 2011-02-28T03:00:28.890Z What is the significance in the fact that the lobster hatches in the "mysis stage"?What are some of the peculiar names given to the larv� in the case of echinoderms, worms, and mollusks? A Guide for the Study of Animals 2011-01-18T03:00:14.913Z There seems to be little or no literature on the central nervous system of this form of echinoderm. Journal of Entomology and Zoology Volume Eleven, Number Two, June 1919 The particles are mostly the broken tests of foraminifera, along with the d�bris of echinoderm and molluscan shells, and many minute bodies, like coccoliths, of somewhat obscure nature. Encyclopaedia Britannica, 11th Edition, Volume 5, Slice 7 "Cerargyrite" to "Charing Cross" The first known denizens of great depths were the foraminifera and few echinoderms brought up by various sounding apparatus. Encyclopaedia Britannica, 11th Edition, Volume 8, Slice 7 "Drama" to "Dublin" These deposits are highly fossiliferous in parts, and contain the remains of pteropods, lamellibranchs and echinoderms, embedded in a foraminiferous deposit mixed with volcanic debris, like the deep-sea muds brought up by 134 the “Challenger.” Encyclopaedia Britannica, 11th Edition, Volume 7, Slice 4 "Coquelin" to "Costume" These would imbed and preserve for us the numerous echinoderms, sponges, and mollusca, which lived upon the bottom, the fishes and turtles which swam in its waters, and sometimes the winged reptiles that flew overhead. Island Life Or the Phenomena and Causes of Insular Faunas and Floras Sometimes they have internal cavities, and very frequently they contain shells of echinoderms, molluscs, &c., partly or entirely replaced by silica, but preserving their original forms. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 7 "Columbus" to "Condottiere" In this torpor the echinoderms and even the molluscs live to-day. Creative Evolution The naturalists of the “Porcupine” and other expeditions found that echinoderms, corals and sponges were often carried up adhering to the outer surface of the dredge and the last few fathoms of dredge rope. Encyclopaedia Britannica, 11th Edition, Volume 8, Slice 7 "Drama" to "Dublin" Beautiful results are thus obtained with echinoderms, zoophytes, worms and marine arthropoda. Practical Taxidermy A manual of instruction to the amateur in collecting, preserving, and setting up natural history specimens of all kinds. To which is added a chapter upon the pictorial arrangement of museums. With additional instructions in modelling and artistic taxidermy. Upon their bottom there gathered a vast mass of calcareous mud, composed in great part of foraminifera, corals, echinoderms, and molluscs. Island Life Or the Phenomena and Causes of Insular Faunas and Floras Also, the hard calcareous external covering of the mollusca, crustacea, and echinoderms. The Sailor's Word-Book An Alphabetical Digest of Nautical Terms, including Some More Especially Military and Scientific, but Useful to Seamen; as well as Archaisms of Early Voyagers, etc. It is all very fine to recognise in the ascending series of protozoa, cœlenterata, echinoderms, worms, mollusks, fishes, amphibia, reptiles, the stages of progress toward birds and finally to mammals and man. The Silesian Horseherd - Questions of the Hour Dividing the vertebrate animals—as Linnæus had already divided them—into mammals, birds, reptiles, and fishes, he divided the invertebrates into molluscs, insects, worms, echinoderms, and polyps. Evolution, Old & New Or, the Theories of Buffon, Dr. Erasmus Darwin and Lamarck, as compared with that of Charles Darwin "It's an echinoderm," he said, "generally with five arms, that lives only in the sea, has a simple stomach, and feeds on the minute organisms in the water." The Boy With the U. S. Fisheries Lamarck thus accounts for the production of the radial symmetry of the medusæ and echinoderms, his Radiaires. Lamarck, the Founder of Evolution His Life and Work In the animal kingdom it occurs as both calcite and aragonite in the tests of the foraminifera, echinoderms, brachiopoda, and mollusca; also in the skeletons of sponges and corals. Encyclopaedia Britannica, 11th Edition, Volume 4, Part 4 "Bulgaria" to "Calgary" A few molluscs, many kinds of worms, echinoderms, and their allies, crab and lobster-like creatures in innumerable different stages of development, are to be found there, while unnumbered polyps and jelly-fish are always present. Thomas Henry Huxley; A Sketch Of His Life And Work The four great branches are the echinoderms, mollusks, articulates, and vertebrates. The Whence and the Whither of Man A Brief History of His Origin and Development through Conformity to Environment; Being the Morse Lectures of 1895 Fancy an ambitious echinoderm claiming a private interview with Agassiz, to demonstrate by verbal arguments that he is a mollusk! The Atlantic Monthly, Volume 09, No. 54, April, 1862 He also showed the distinctness of echinoderms from polyps, thus anticipating Leuckart, who established the phylum of Cœlenterata nearly half a century later. Lamarck, the Founder of Evolution His Life and Work Then it was on the radiates, echinoderms, acalephes, polypes, entozoons, sponges, and infusoria, that he had for such a long time burned the midnight oil? Dick Sand A Captain at Fifteen Such forms he distinguished as Coelentera, and showed that they had no special affinity with echinoderms, polyzoa, &c. The Project Gutenberg Encyclopedia Volume 1 of 28 The echinoderms, including starfishes, sea-urchins, and others straggled early from the great army. The Whence and the Whither of Man A Brief History of His Origin and Development through Conformity to Environment; Being the Morse Lectures of 1895 Bivalve and univalve mollusca seem to be rare at the greatest depths; but starfishes, sea urchins and other echinoderms, zoophytes, sponges, and protozoa abound. Discourses Biological and Geological Essays Already the collections of insects, crustacea, worms, molluscs, echinoderms, corals, etc., at the Museum were enormous. Lamarck, the Founder of Evolution His Life and Work Of these we have no interest just now in the echinoderms, molluscs, and articulates, as they are independent branches of the animal-tree, and have nothing to do with the vertebrates. The Evolution of Man — Volume 2 This we find in the lower cnidaria and worms, as well as in the more highly-developed molluscs, echinoderms, articulates, and vertebrates. The Evolution of Man — Volume 1 Agassiz had asked him for some help in his work upon echinoderms. Louis Agassiz: His Life and Correspondence If it is more culpable to kill an ignorant human savage than an elephant, it is also more culpable to kill an elephant than an echinoderm. The Minds and Manners of Wild Animals A Book of Personal Observations These shells and armors begat a kind of torpor and immobility which has continued down to our day with the echinoderms and mollusks, but the arthropods and vertebrates escaped it by some lucky stroke. Time and Change Of the higher, free-moving classes of the echinoderms, starfish are more numerous than in the Cambrian, and sea urchins make their appearance in rare archaic forms. The Elements of Geology Hertwig has shown that the tiny transparent ova of the echinoderms are the most convenient for following the details of this important process of impregnation. The Evolution of Man — Volume 1 The collections here, therefore, were small; but a good haul was made with the trawl net, which gathered half-a-dozen species of echinoderms, some small fishes, and a number of shells. Louis Agassiz: His Life and Correspondence They are the Sphaeronites of old authors, and were considered by Professor E. Forbes as intermediate between the crinoids and echinoderms. The Student's Elements of Geology Among the echinoderms, notable for being covered with spines: starfish, feather stars, sea lilies, free–swimming crinoids, brittle stars, sea urchins, sea cucumbers, etc., represented a complete collection of the individuals in this group. Twenty Thousand Leagues Under the Sea Among the echinoderms, crinoids are now exceedingly abundant, sea urchins are more plentiful, and sea cucumbers are found now for the first time. The Elements of Geology The way was opened through this obscure province by the studies of the famous Berlin zoologist, Johannes Muller, on the echinoderms. The Evolution of Man — Volume 1 An ardent student of the early fossil echinoderms, it was a great pleasure to Agassiz to gather their fresh and living representatives. Louis Agassiz: His Life and Correspondence At the same time, some of the accompanying bivalve shells, echinoderms, and zoophytes, are specifically identical with fossils of the true Cretaceous series. The Student's Elements of Geology The zoophyte branch offered some very unusual specimens from its two groups, the polyps and the echinoderms. Twenty Thousand Leagues Under the Sea The cystoid reaches its climax, but there appear now two higher types of echinoderms,—the crinoid and the starfish. The Elements of Geology In particular, the indefatigable Russian zoologist, Kowalevsky, found them in all the most diverse sections of the invertebrates—the worms, tunicates, echinoderms, molluscs, articulates, etc. The Evolution of Man — Volume 1 Especially has the minute examination of the thickness of the test in echinoderms revealed to me unexpected relations between the sea-urchin and the medusa. Louis Agassiz: His Life and Correspondence At Claiborne, in Alabama, no less than 400 species of marine shells, with many echinoderms and teeth of fish, characterise one member of this system. The Student's Elements of Geology Our dragnets brought up many specimens of polyps and echinoderms plus some unusual shells from the branch Mollusca. Twenty Thousand Leagues Under the Sea Is this not quite a parallel case with the monkeys and pachyderms? for once crinoids were the only representatives of the class of echinoderms. Louis Agassiz: His Life and Correspondence No more ice, not much of echinoderms, plenty of fish, recall of ambassadors in partibus, and great severity toward the book-sellers, an infernal race, two or three of whom have been killed under me. Louis Agassiz: His Life and Correspondence The pentacrinites, the lowest of the echinoderms, have only one living representative in tropical America, where we find at the same time the highest and largest spatangi and holothuridae.
