A new species of Nembrotha nudibranch (also known as sea slug) that was discovered during the California Academy of Sciences' 2011 Philippine Biodiversity Expedition
No sign of hippogriffs or screaming Mandrake plants yet, but Potter fans take heart: the Blast-Ended Skrewt, a shell-less lobster with no visible head but a very bad temper may exist after all. First sighted in "Harry Potter and the Goblet of Fire," the skrewt turns out to have some Muggle-world friends, in the form of three new species of shell-less lobsters that were one more great find by the Philippine expedition. Unlike the Hogwarts skrewts, those from the Philippines are very timid — spending most of their time squeezed into rock crevices. That makes sense; when you've got the lobster family name but no armor to back it up, it's best to keep a low profile.
