The name pedicellaria comes from the Latin root words ped- meaning foot and -icellus meaning little. In the course of purification studies on the pedicellarial venom of T. pileolus, we have found that the venom contains lectin components (Nakagawa et al. The final purification was achieved using an immobilized D-galactose column (2 ml) equilibrated with 150 mM phosphate buffer solution (Na2HPO4 73 mM, KH2PO4 37 mM, NaCl 40 mM) (PBS) (pH 7.2). They are typically attached to the echinoderm body at the base of the spines. The Division of Invertebrate Zoology of the Society for Integrative and Comparative Biology joins with AMS in promoting the journal, which is co-published with Blackwell Publishing. Delle Chiaje, in his work on invertebrate animals, asserted that pedicellari formed an integral portion of the Echinus, and were simply appendages of the test.

Rostra are found only among irregular echinoids and have narrow, slightly curved valves that come together at the ends. SUL-IA is a monomeric protein with a molecular weight of 32 kDa.
