Day 21: Taillbud Stage



This photo was taken Friday, only 2 days after the photos of the neural tube folding!  These guys are developing quickly.  They are about a 1/4" in length, about the size of a pencil tip.  This is the tailbud stage and you can easily make out the start of the tail, eyes, mouth, and backbone.  I can't tell if the buds under the neck area are arms or what will be the external gills of the larval stage.  We'll find out soon.

  1. They look like manatees! Love how you can see the detail of the backbone. Very cool.

  2. They do look like manatees! The detail is cool, it will be interesting to see when the gel outter covering breaks down at what stage the little guy will be.
