The posterior of the two brain vesicles formed by specialization of the rhombencephalon in the developing embryo, it comprises the medulla oblongata. [TFD][VHOG]

UBPROP 0000003

The early development of most vertebrate brains is similar (...). The zebrafish neural tube follows the same basic differentiation pattern as the mammalian neural tube (reference 1); The brain develops from three embryonic enlargements of the neural tube, which later differentiate into five regions. A forebrain differentiates into telencephalon and diencephalon. The midbrain, or mesencephalon, remains undivided. The hindbrain divides into the metencephalon and myelencephalon. Cavities within the brain enlarge to form a series of interconnected ventricles (reference 2).[well established][VHOG]

the terms metencephalon and myelencephalon are only meaningful in mammals and birds - Neuroanatomy of the Zebrafish Brain. Note that its not clear if this refers to the developing medulla oblongata - MA (adult) has two distinct classes
