a fish
Most fish lay eggs, so the embryo develops there. In viviparous or oviviviparous fish, the development is often in the oviduct.
An embryo is protected within the mother's uterus by the amniotic sac, which contains amniotic fluid to cushion and support it. The uterus also provides a physical barrier and nourishment through the placenta, which facilitates the exchange of oxygen, nutrients, and waste products between the mother and the embryo. Hormones produced by the mother and the embryo help to maintain the pregnancy and support the embryo's growth and development.
A fish embryo feeds from the yolk in the egg. Once they are hatched, they still have a supply of yolk in a sac to last them for a few days.
