Arbacia dufresnei The Biggest of All Time!
54.2 mm     Antarctic, Petermann Island     465,00 €
Item# 0004050472
FamilyECHINOIDEA
NameArbacia dufresnei - The Biggest of All Time! , (Blainville, 1825)
Size54.2 mm
LocalityAntarctic, Petermann Island
NoteGEM. The biggest of all time. Crazy mega giant specimen and probably the largest specimen ever offer in Shellauction. Much larger than the maximum known size reported in Heinke's book - "Sea Urchins" of 50mm diameter. The usual size is 25mm ~ 35mm. Thus at 54.2mm, it dwarf any specimen you seen online. Perfectly cleaned with apical disc fully intact and preserved with the 4 conspicuous anal plates. Absolutely stunning blight green colour with lovely cleaned and beautiful tubercles. Found by trawling in 100m deep, Dec 2001. My very last pc and the biggest one I kept for decades. Rarely seen such a huge specimen that comes with the preserved 4 conspicuous anal plates. Top collector pc! Click on the second photo to see higher resolution and clearer image.
