Hydrophis belcheri
Belcher's sea snake, which many times is mistakenly called the "hook-nosed sea snake" ("Enhydrina schistosa"), has been erroneously popularized as the most venomous snake in the world, due to Ernst and Zug's published book "Snakes in Question: The Smithsonian Answer Book" from 1996.
Associate Professor Bryan Grieg Fry, a prominent venom expert, has clarified the error: "The hook nosed myth was due to a fundamental error in a book called 'Snakes in question'. In there, all the toxicity testing results were lumped in together, regardless of the mode of testing (e.g. subcutaneous vs. intramuscular vs intravenous vs intraperitoneal). As the mode can influence the relative number, venoms can only be compared within a mode. Otherwise, its apples and rocks.". Studies on mice and human cardiac cell culture shows that venom of the inland taipan, drop by drop, is the most toxic among all snakes; land or sea. The most venomous sea snake is actually Dubois' seasnake ("Aipysurus duboisii" ).
Spectral bat
The spectral bat ("Vampyrum spectrum"), also called the great false vampire bat or Linnaeus's false vampire bat, is a large, carnivorous leaf-nosed bat found in Mexico, Central America, and South America.
It is the only member of the genus Vampyrum; its closest living relative is the big-eared woolly bat.
It is the largest bat species in the New World, as well as the largest carnivorous bat: its wingspan is .
It has a robust skull and teeth, with which it delivers a powerful bite to kill its prey.
Birds are frequent prey items, though it may also consume rodents, insects, and other bats.
