All isolates are seven days old. A) Aboral half from eight cell stage embryo. Note the anterior pneumatophore rudiment (arrow). B) Oral half from same eight cell stage embryo as (A). Note the anterior tentacle with a cnidoband and the posterior mouth and pigment cells. C) Aboral half from eight cell stage embryo. Note the lack of a mouth and tentacle.

D) Oral half from 15 hour embryo. The embryo has a mouth and a tentacle rudiment. The arrow points to an abnormal nectophore rudiment. E) Oral half from the same eight cell stage embryo as (C). Note the mouth and tentacle. F) Oral half from 22 hour embryo. The embryo has an anterior protrusion, a tentacle with a position along the body which is more anterior than normal and a posterior mouth. All photographs are at the same magnification. The bar indicates 50 of the embryo is specified to form the nectophore some time prior to the eight cell stage. Oral isolates produced at early developmental stages can form a normal larva with a nectophore, tentacle, and mouth. While the larva is smaller than normal, the.
