• The everted sac experiments are prone to methodological errors, especially damage caused by the everting procedure, but we took great care to minimize these.

• No trematodes were observed in the lung or air sac, heart, liver, spleen and kidney of all bats and swallows.

• To bypass some of the potentially complex requirements for fertilisation, we used isolated embryo sacs rather than isolated egg cells.

• The visceral yolk sac, allantois and amnion were dissected away from the fetal material and excess fluid was wiped clear prior to measuring the weight.

• The exocoelomic cavity contains the yolk sac, which is connected to the primitive digestive tract and fetal circulation.

• Tested organs include lung or air sac, heart, spleen, liver, kidneys and intestine.

• Various-sized blebs developed in the area between the oral sucker and ventrogenital sac.

• This in turn was shown to depend on the growth rates of the embryo and embryo sac, both of which differed between genotypes.

• We estimate that two experimenters can microinject a maximum of 15 embryo sacs per experiment with a 14% success rate of injecting recipient cells.

• The trend was in the order yolk sac endoderm epiblast derivatives > placenta.

• The eye movement classification is indicated in the upper left corner of the histogram (saccade sac, mixed mix, position 0drift activated pos).

• These two tubes expand partially into five pairs of sac-like structures.

• Part of the filler wire protruded from the final sac.

• Visualisation of the complete cervical canal with a gestational sac over it and an empty uterine cavity confirms placental insertion in the scar.

• The paired ovaries of these caecilians are elongated sac-like structures each including numerous vitellogenic follicles.
