08-FEB-2006: Here is one of my pregnant Artemia SeaMonkeys - Age: 42 days - Size: ~10mm.
Enjoy this incredible close-up photo - even the individual eggs in the egg-sack (uterus or brood pouch) are visible!
One individual egg has a diameter of about 250(!) micrometer(!).

1. male graspers to hold the female during the reproduction process; bent back due fast swimming speed
2. male reproduction organ
16-FEB-2006: Artemia Head of a female - Age: 50 days
This female is already grown up (the one in the 2 photos above). The photo clearly shows the left and right eye (dark-brown circles),
aswell as the remnants of the nauplius eye in the middle (dark-brown spot in between of the large eyes).
16-FEB-2006: Artemia female while excretion - Age: 50 days
1. End of the tail; 2. "fins" on the tail; 3. oocytes in ovaries; 4. the uterus or brood pouch
Clearly visible that the tail "extends" - this is animal feces. A few seconds after taking this photo
it fell off. Furthermore there are some white dots (3) near the uterus (brood pouch) -
Those are oocytes (eggs in development) in the ovaries.
17-FEB-2006: Artemia brood pouch and ovaries of a female (eggs in uterus and 2nd brood developing) - Age: 51 days
Here we have a photo of the brood pouch and ovaries - the ovaries themselfs are not visible, but
the eggs in development (oocytes) are the light-yellow dots along the tail. As the eggs progress in
development, they get bigger and are pushed into the uterus (brood pouch).
19-FEB-2006: Artemia female ovaries with empty brood pouch - Age: 53 days
The first brood is already born and the brood pouch is empty. But the next broods eggs are already
developing in the ovaries. Recognize the lined up eggs left and right of the gut. The eggs get slightly
bigger near the brood pouch. This indicates that those are the more ripe eggs and they will soon be
pushed into the brood pouch for further development.
19-FEB-2006: Artemia female - Age: 53 days
Here we have a top view of the female: As described in the upper right photo, one can clearly
see the ovaries (left and right of the gut near the brood pouch) where the new whitish eggs are produced.
The brood pouch itself is currently empty since all other nauplii have been released.
