Here are some images from Chad DeVoe's 7th grade life science classes at Groton Middle School.
BEAUTIFUL. Thanks, Guys!
First up- the "eyed" egg. Notice the visible eye and head. Its just about ready to hatch...
And here is a new-born "alevin", or "sack-fry". The attached yolk-sack will provide nutrition for the first 3-4 weeks in our aquarium setting.
We will be able to observe capillary formation, as the alevins utilize their food source. The yolk sacks will gradually be incorporated into the growing digestive tract. The alevins will also be growing gills, fins and a mroe complete body-structure in teh coming weeks. All viewable in class!
