Name: Halieutichthys intermedius
Common Name: The Louisiana Pancake Batfish
How it made the Top 10: This species was discovered just before the Gulf of Mexico oil spill in 2010 and its entire known distribution is in the region of the spill. It is also a remarkably hideous (in a good way) animal. It is flat like a pancake, spikey, hops on its fins and has huge bulging eyes. Its discovery and precarious existence due to the oil spill was the lead article on cnn.com and a number of other outlets.
