The news is bleak for North Atlantic right whales, a critically endangered species with only around 400 left.  After a year which saw 18 known deaths (most of which are due to getting tangled up in fishing gear), there have been no new calves sighted this year, worsening an already downward trend in births.  That kind of math doesn’t bode well for the future of this species.

The Boston Globe has a longer article on this if you’re interested.
