The otocysts contain smaller otoliths, and they are irregular in shape; the heart tube is attached by a thin strand of cells to the pericardial wall; and blood cells pool on the ventral side of the embryo at the level of the hindbrain and along the length of the tail.
The hindbrain (hb) develops just posterior to any retinal tissue, but the otocysts have been deleted.
