Strongylocentrotus pallidus Sars 1871 (Str. sachalinicus as junior synonym)

Family: Strongylcentrotidae

Order: Echinoida

Locality: Japan, The Sea of Japan, off Nigata, 500 m

Dimensions: 59 Ø x 28 mm


I got this specimen as Echinus lucidus, but this taxon was apparently wrong, because Echinus has only three pore-pairs. After cleaning with bleach the former more or less violet colour disappeared and the test became green.
