Dear colleagues,
There are two important papers on intracellular calcium phosphate granules
in Nephtys, that might be interesting to look at, since they indicate a
(another) unique feature of these worms. The papers are:
Bryan GW & PE Gibbs 1986 Occurrence, composition and function of
intracellular calcium phosphate granules in the musculature of nephtyid
polychaetes (Annelida). J. Mar. Biol. Ass. U.K. 66:343-365
(Abstract: 40 species from 26 polychaeta familes were analysed; most had
less than 1% DW of Ca and P; Nephtys has 3-6% dw of Ca and 2-4.5% dw of
P).
Gibbs PE & GW Bryan 1984 Calcium phosphate granules in muscle cells
of Nephtys (Annelida, Polychaeta) -- A novel skeleton? Nature 310:494-495
(p. 495: "We suggest that a novel flexible skeleton has evolved in _Nephtys_
as an integral part of its highly successful burrowing mechanism").
Best wishes,
Sergio
