At four days, nearly the entire body of the
embryo has risen off the yolk and turned to lay
on its left side. The upper portion of the
embryo is even more curved and the tail is also
beginning to curve. The heart is the dark red
area within the upper curve of the embryo. Just
a fraction of an inch from the heart, the eye is
visible. The large node just above and to the
right of the eye is a portion of the brain.
