Danionella dracula, named after Bram Stoker's famed vampire, is a 16-millimetre-long Southeast Asian fish with a big bite.
Phallus-shaped mushrooms and bioluminescent-bombing worms - now those are important scientific discoveries.
The top 10 new species of 2010 have been announced by Arizona State University's International Institute for Species Exploration. It is an annual list that raises awareness of global biodiversity .
Attenborough's Pitcher (Nepenthes attenboroughii)
The pitcher plant is named after British broadcaster Sir David Attenborough to commemorate his 80th birthday.
The nepenthes attenboroughii is an endangered, football-sized plant found in Palawan, an island province of the Philippines. It is a carnivore that feeds off of insects trapped in its fluid-filled, 30-by-16-centimetre pitcher.
Bombardier Worm (Swima bombiviridis)
The translucent, deep-sea annelid is found off the central coast of California and has no affiliation to the Canadian transportation company. Commonly referred to as the Green Bombers, this deep sea worm has the ability to shoot off bomb-like gills that glow green for defensive purposes.
Udderly Weird Yam (Dioscorea orangeana)
The unsightly but edible yam was discovered in the unprotected, harvest-heavy, northern part of Madagascar. Authors have called for this multiple-lobed yam to be listed as "critically endangered."
Bug-eating Slug (Aiteng ater)
Found in Pak Phanang Bay, Thailand, the aiteng ater is named after a jovial shadow puppet from plays popular with the locals. Most slug species eat algae but this mud-dwelling slug feasts on insects.
Far-out Frogfish (Histiophryne psychedelica)
This "psychedelic frogfish" can be found in Indonesia and is part of the Antennariidae family. A unique, maze-like pattern adorns its flat face that can work defensively by helping it blend into coral reefs.
Uber Orb-weaver (Nephila komaci)
Also known as Komac's golden orb spider, it is largest and first Nephila species to be discovered since 1879. Female spiders can be as long as 39.7 mm, while males only grow to be 8.7 mm. It is suspected of being endangered and can be found in Maptuland or Madagascar.
Small Favour (Phallus drewesii)
The two-inch stinkhorn mushroom is part of the Phallaceae family and grows on wood. It was discovered in 2009 on the African island Sao Tome. They emit a foul odour similar to rotting meat. In a span of four hours, they grow from egg to an elongated mushroom.
Fanged Fish (Danionella dracula)
This 16-millimetre-long fish has bite. Named after Bram Stoker's Dracula, the males are adversarial and often spar with each other. They were first discovered in Burma and continue to be indigenous to the area.
They are believed to be the first to have vampire-like teeth in the Cyprinidae family of freshwater fishes.
Short-circuited Electric Fish (Gymnotus omarorum)
This fish can be found in Uruguay in local streams and lagoons. For over 30 years, scientists have shown interest in studying the Gymnotus omarorum for its electrical organ physiology.
Killer Sponge (Chondrocladia (Meliiderma) turbiformis)
The deep-sea sponge was discovered more than 10 years ago as being part of the carnivorous Cladorhizidae family. They flourish in the Pacific and can be found near New Zealand.
