What's the difference between brachiopod and deltidium?

Brachiopod

Definition:

(n.) One of the Brachiopoda, or its shell.

Example Sentences:

(1) In contrast to hemoglobins, ligand binding to the deoxy and met forms is noncooperative for brachiopod (and sipunculid) Hrs.
(2) This carotenoid-protein complex was isolated from within the calcite shell of three different brachiopod genera and may therefore be involved in the process of biomineralization.
(3) The deduced translation products of brachiopod en and ciD share high levels of sequence identity with their Drosophila homologues.
(4) The crustaceans and the ascidian, Ciona intestinalis, displayed strongest activity, with low levels found in the starfish, Asterias rubens, the sea urchin, D. antillarum, and the brachiopod, Liothyrella uva.
(5) Spectroscopic comparisons of the sipunculid and brachiopod Hrs show no significant differences in the active site structures; therefore, modulation of oxygen affinity is attributable to effects linking the site to quaternary structural changes in the octamer.
(6) The red colour of some terebratulid brachiopod shells is caused by a small chromoprotein that occurs within the calcium carbonate matrix of the shell.
(7) The fine structure of the shell and underlying mantle in young juveniles of the articulate brachiopod Terebratalia transversa has been examined by electron microscopy.
(8) Single myosin control is present in the muscles of molluscs, brachiopods, echinoderms, echiuroids, and nemertine worms.
(9) Of the 11 species examined, 3 bivalves, 2 ophiuroids, 2 isopods, 1 amphipod, and 1 polychaete breed year-round, and 1 brachiopod and 1 scaphopod spawn seasonally.
(10) Chemical and spectroscopic consequences of allosteric interactions for ligand binding to sipunculid (Phascolopsis gouldii) and brachiopod (Lingula reevii) hemerythrins (Hrs) have been investigated.
(11) The morphology of the mantle in free-swimming and metamorphosing larvae of the articulate brachiopod Terebratalia transversa has been examined by scanning and transmission electron microscopy.
(12) We have used the polymerase chain reaction (PCR) to amplify, clone and sequence homologues of the Drosophila segment polarity genes engrailed (en), cubitus interruptus Dominant (ciD) and wingless (wg) from the genome of the brachiopod, Terebratulina retusa (Linnaeus).
(13) Reported are results on the subunit composition of octameric hemerythrin (Hr) from the brachiopod Lingula reevii.
(14) The partial N-terminal amino acid sequence of the protein is virtually identical in three different brachiopod genera, indicating homology.
(15) The orientation relationship between apatite and organic matrix in shell of Lingula unguis (inarticulate brachiopod) was studied.
(16) Very recently, one other Hr, that from the brachiopod Lingula unguis, was also shown to contain equimolar proportions of two different subunits [Satake, K., Yugi, M., Kamo, M., Kihara, H., & Tsugita, A.
