Summary

This is a drawing of a human fetus at 10 weeks' <a href="https://en.wikipedia.org/wiki/gestational_age" class="extiw" title="wikipedia:gestational age">gestational age</a> (i.e. 8 weeks after fertilization).

This particular picture was drawn by Melchior Meijer who is a 3D artist. He and 3Dpregnancy.com used various resources to produce the illustration, including books, DVD's and websites to verify how a fetus looks at this stage of development.

Sources for assessment of accuracy

Some of the resources relied upon to create this image were as follows:

When comparing this image to other images, it should be kept in mind that this stage of development is often referenced using different numerical descriptions. This is an approximate drawing of a fetus eight weeks after <a href="https://en.wikipedia.org/wiki/fertilization" class="extiw" title="wikipedia:fertilization">fertilization</a>, i.e. at the beginning of the ninth week after fertilization. This is equivalent to a <a href="https://en.wikipedia.org/wiki/gestational_age" class="extiw" title="wikipedia:gestational age">gestational age</a> of about ten weeks, i.e. at the beginning of the eleventh week of gestational age. This drawing can be compared to other online images of a fetus at approximately the same stage of development, including the following images:

VIII. <a href="//commons.wikimedia.org/wiki/File:Human_fetus_10_weeks_-_therapeutic_abortion.jpg" title="File:Human fetus 10 weeks - therapeutic abortion.jpg">Photo</a> of intact fetus removed from 44 year-old female who was diagnosed with carcinoma in situ of cervix (early stage cancer of womb). Abortion was deemed inevitable for future health of the woman. This fetus is at 10 weeks gestation (i.e. from LMP), instead of 10 weeks from fertilisation.

Note that by the fetal stage, the tail is gone. See <a rel="nofollow" class="external text" href="http://www.mayoclinic.com/health/prenatal-care/PR00112">Mayo Clinic website.</a> An atrophied embryonic tail bud remains, but typically there is no tail.<a rel="nofollow" class="external autonumber" href="http://www.embryology.ch/anglais/jfetalperiod/entwicklung01.html">[2]</a> Additionally, note that a human fetus does not have gills.

Also see James S. Trefil <a rel="nofollow" class="external text" href="http://books.google.com/books?id=JVj9SylSuB4C&pg=PA309&dq=gills+and+fetus+embryo&sig=EfRf062fMxIoyKEYGtcIwu0O3Lc">The Nature of Science</a>, page 309 (2003). A fetus 8 weeks after fertilization is typically about 1.25 inches crown to rump. This donor-approved image is in black and white, although the originally-uploaded version is in a pinkish color. According to the pro-choice organization <a rel="nofollow" class="external text" href="http://www.lifeandlibertyforwomen.org/printer_friendly_pages/truth_about_photos.pdf">"Life and Liberty for Women"</a>, the color of a fetus after removal from the uterus (e.g. after an abortion) depends upon the method of removal. Gray skin will result from “laminaria through an intra-amniotic injection." On the other hand, "If the procedure was done while the fetus was alive, its skin would be the pinkish color....", as in the drawing that was originally uploaded.
