Animals were transported into the laboratory, separated according to sex, and kept individually in finger bowls. Animals were kept at 18 ° C on a seawater table. Freshly spawned eggs were mixed with active sperm isolated from a ripe male and diluted in seawater (Lowe et al. 2004). Fertilization envelopes were ruptured using fine forceps, and embryonic and juvenile stages were collected using Pasteur pipettes. Embryos were relaxed in a mix of 7 % MgCl 2 and seawater (1: 1) for 5 – 10 min prior to fixation for transmission electron microscopy (TEM) and scanning electron microscopy (SEM)		1	2007-09									United States of America	Massachusetts	Woods Hole	Adult	https://treatment.plazi.org/id/AB59ED17564FFFBEFF16FC30FC9EFF7D#9398565C564FFFBFFF16FBF2FE4DFA31				MaterialCitation
