在高压舱中，一个活的成熟庞贝螺标本承受了8.05兆帕（80.5公斤/平方厘米）的静水压力，相当于785米深的海水。此后，它被炮弹的内爆立即杀死。在内爆之前，动物对不断增加的压力做出了生理反应。785 m的深度可被指定为凤尾莲的深度极限。这一结果对具有相似壳的已灭绝鹦鹉螺和菊石的古生态学和古生物学解释具有重要意义。
In a hyperbaric chamber, a living mature specimen of N. pompilius withstood a hydrostatic pressure of 8.05 MPa (80.5 kg/cm2), equivalent to 785 m deep in the sea. Thereafter it was killed instantly by implosion of the shell. Before implosion, the animal reacted physiologically to increasing pressure. The depth of 785 m can be assigned as the depth limit of N. pompilius. The result bears on critical interpretations of the paleoecology and paleobiology of extinct nautiloids and ammonoids with similar shells.
