Ectopic Pregnancy - Abdominal - Fatal to mother and fetus at ~30 weeks due to placental abruption

This is far more developed than most ectopic pregnancies become, and prior to 1999, there were no documented cases where both mother and child survived (and were healthy/not extremely premature) during an ectopic pregnancy.

The Mastoid Vault

The vault behind the ear is opened for a mastoidectomy - removal of part of the mastoid bone to drain infection of the mastoid air cells (mastoiditis). 

The mastoid is a very interesting part of the anatomy of the skull, though I may be a bit biased; at age 7, I had a bilateral mastoidectomy. In today’s era of antibiotics and other interventions to care for pediatric otitis media and other ear problems, having a single mastoidectomy called for is very uncommon, and a bilateral mastoidectomy (on both sides of the head) pretty much unheard of.

1. Risso’s Dolphin

2. Beluga Whale

3. Narwhal

4. Chinese River Dolphin [Baiji]

The Baiji is now thought to be completely extinct. It was declared functionally extinct in 2006, since there were no populations of the species left, and the few recent sightings (as in the past 10 years) were of solitary dolphins that were already clearly high in age.

The sad truth is that any large animal hoping to live within the Yangtze catchment area is probably not going to make it. Over 12% of the world’s population lives in that comparatively tiny zone, and damming the river, allowing heavy pollution, and re-routing the water for agriculture, makes it an extremely harsh environment.

Despite the extinction of one of the world’s four fresh-water dolphins, the other dolphin that lives near China,  the Chinese White Dolphin, is actually stable in population right now. Thanks to eco-tourism and Hong Kong-based dolphin watching boat trips, it’s far more profitable to support the population and help bolster it, than to hunt it for the comparatively small amount of food it can bring in.
