Camera lucida sketches of the zebrafish embryo at selected stages. This image is in the Blastula period at the 4.7 hour 30% epiboly stage. The animal pole is to the top for the early stages, and anter...

Camera lucida sketches of the zebrafish embryo at selected stages. This image is in the Gastrula period at the 8 hour 75% epiboly stage. The animal pole is to the top for the early stages, and anterio...

Camera lucida sketches of the zebrafish embryo at selected stages. This image is in the Gastrula period at the 10 hour bud stage. The animal pole is to the top for the early stages, and anterior is to...

Camera lucida sketches of the zebrafish embryo at selected stages. This image is from the Pharyngula period at the 25 hour Prim-6 stage. The animal pole is to the top for the early stages, and anterio...

This study of the zebrafish eye is a series of four images taken at increasing magnifications. This image, the first image is the SEM block face of the zebrafish eye. This is followed by a second im...

This study on the zebrafish optic tectum is a series of four images with magnifications ranging from the SEM block face overview to of the zebrafish head to high magnification (80,000X) showing optic ...

Prewave pulse and axial wave. This prewave pulse appears to arise predominantly from the animal pole region, others however appear to emerge nearly simultaneously over large regions of the blastoderm...

Pre-wave pulse (PWP). The apparently whole-embryo calcium pulse appears to initiate (the PWP region on the wave graphs) over a widespread area of blastoderm, possibly earliest at the animal pole, and...

Four cell stage zebrafish embryo, stained with 100 micromolar Bodipy 505/515. In the upper portion of the image, the yolk cell contains large spherical yolk platelets. The blastomeres undergoing merob...
