Aspidodiadema Jacobi
''Aspidodiadema'' is a genus of echinoderms belonging to the family Aspidodiadematidae. The species of this genus are found in the Indo-Pacific and Caribbean. Description The test is small and subglobular with fragile plating which is firmly tessellated. The apical disc is monocyclic. The plates membrane is embedded and does not touch the coronal plates. The ambulacral plating is pseudocompound with single large primary tubercle on every third plate which is much enlarged compared to the others. The primary tubercles form an alternate series down the perradius. These traits distinguish this genus from ''Plesiodiadema'' and ''Gymnotiara.'' The primary tubercles are perforated and notched. The secondary tuberculation confined to plate margins. The peristome has shallow, rounded buccal notches. The spines are slender and arranged in whorls. The lumens are filled with a mesh of horizontal dividers and vertical pillars. Species The following species are recognised: *''Aspidod ...

Aspidodiadema Jacobyi
''Aspidodiadema jacobyi'' is a small sea urchin in the family Aspidodiadematidae. It lives in tropical seas at great depths. Aspidodiadema jacobyi was first scientifically described in 1880 by Alexander Emanuel Agassiz, an American scientist. Description ''Aspidodiadema jacobyi'' has a globular hard test or shell protecting the inner organs. The mouth has 10 buccal plates and small rounded buccal notches and is on the oral (bottom) surface which is slightly flattened. The aboral (top) surface has a small coronal ring of tubercles surrounding the anus. The test is composed of 5 radial ambulacral sets of 3 plates, separated by 5 ambulacral grooves. There are rows of pairs of pores between the ambulacral areas through which the tube feet protrude. Every third row of plates is larger than the other 2 and has a zig-zag row of large primary tubercles. This row does not extend quite as far as the other 2 rows of plates which have similar primary tubercles set serially in a straight lin ...

Echinoderm
An echinoderm () is any animal of the phylum Echinodermata (), which includes starfish, brittle stars, sea urchins, sand dollars and sea cucumbers, as well as the sessile sea lilies or "stone lilies". While bilaterally symmetrical as larvae, as adults echinoderms are recognisable by their usually five-pointed radial symmetry (pentamerous symmetry), and are found on the sea bed at every ocean depth from the intertidal zone to the abyssal zone. The phylum contains about 7,600 living species, making it the second-largest group of deuterostomes after the chordates, as well as the largest marine-only phylum. The first definitive echinoderms appeared near the start of the Cambrian. Echinoderms are important both ecologically and geologically. Ecologically, there are few other groupings so abundant in the deep sea, as well as shallower oceans. Most echinoderms are able to reproduce asexually and regenerate tissue, organs and limbs; in some cases, they can undergo ...
