There are said to be some 35,000 species of snail, including terrestrial and aquatic species. Snails hail from the Mollusca phylum, the second largest phylum of invertebrates, and gastropods (snails and slugs) account for about 80 percent of it. Gastropods are nearly as diverse as insects. Snails sometimes come with naturally armored, ornate, or transparent shells. Some glow. Others could kill a person. Here are 10 of the most fascinating and unique-looking snail species on the planet. 1 of 10 Candy Cane Snails LagunaticPhoto / Getty Images The candy cane snail (Liguus virgineus) is possibly the most colorful gastropod in the world. Sporting a white, conical shell decorated with distinctive rainbow-colored stripes, the charismatic snail can be found in the Caribbean — particularly on the island of Hispaniola. The candy cane snail is arboreal (it lives in trees), but it lays its eggs in the sand. 2 of 10 Sea Butterflies helovi / Getty Images Not all snail species are air-breathing, though. Sea butterflies (Thecosomata) are a suborder of pelagic snails. Instead of crawling along the moist forest floor, their feet have evolved into wing-like lobes that allow them to swim around in the top roughly 80 feet of the Arctic and Southern Oceans. They are the world's most abundant gastropod, but they are threatened by ocean acidification. A number of species have lost their shells entirely to this phenomenon, and having no shell leaves their fragile skeletons naked and vulnerable. 3 of 10 Giant African Snails Paul Starosta / Getty Images Giant African snails (Achatina fulica) are the largest known land gastropods. They usually reach about 7 inches long from nose to tail and roughly 3.5 inches in diameter, but the largest ever recorded was a whopping 15.5 inches long. Unsurprisingly, they are voracious eaters, known to feed on some 500 types of plants. It's because of their insatiable appetites that they are considered an invasive species in the U.S. If fruits or vegetables are not available, the snails will devour whatever is available, including the paint and stucco on houses. (Don't worry — they're vegetarian.) 4 of 10 Golden Elephant Snails shadowshador / Flickr The mango-colored golden elephant snail (Tylomelania zemis), otherwise known as the rabbit snail, has several distinguishing features. Firstly, its bright shade is quite recognizable, but not more so than its bunny-like "ears" and elephant-centric "trunk," hence its common names. The freshwater species also has an especially long, conical shell. The golden elephant snail has an extremely limited distribution, mostly restricted to Indonesia's Lake Poso and Malili Lake systems. It really does use its trunk to search for food in the sand, but the "ears" are actually antennae. 5 of 10 Melting Snails Leonardo Castro / Flickr Flat-bodied South American snails are also called "melting" snails (Megalobulimus capillaceus) because their pancake-thin bodies appear to spill out like melting butter on all sides of their shells. They are air-breathing and endemic to San Martín, Huánuco, and Cusco, Peru, although some scientists define the Cusco population as a whole other species (Megalobulimus florezi). There are more than 50 species within the genus genus Megalobulimus, belonging to the subfamily Megalobuliminae. 6 of 10 Geography Cones Reinhard Dirscherl / Getty Images The geography cone (Conus geographus) is a common type of snail that occurs in the Red Sea, Indian Ocean, the Indo-Pacific region, and off the coast of Australia. Its shell has a distinctive mottled appearance and is highly coveted among collectors, but what really sets it apart from other snails? It's the most venomous snail — and, in fact, one of the most venomous creatures — in the world. It fires a complex concoction of toxins via a harpoon-like tooth propelled from an extendable proboscis at speeds of up to 400 mph. 7 of 10 Violet Sea Snails CatMiche / Getty Images The beautiful purple shell of the violet sea snail (Janthina janthina) is only part of what makes this gastropod so interesting. Otherwise known as the bubble-raft snail, the critter collects bubbles in its mucus, then uses its bubbly concoction as a raft for long-distance ocean travel. Floating is their only means of transportation as they cannot swim. They can be found in warm tropical and temperate waters worldwide but high concentrations of them occur in the subtropical Atlantic, Indian, and Pacific oceans. 8 of 10 Opisthostoma Snails Claude & Amandine EVANNO / Flickr Opisthostoma is a genus of tiny land snails with some of the most fascinating shells in the snail world. Many species from this genus have shells that twist in complicated, tangled axes, but the species with the most ornate exterior is perhaps the Opisthostoma vermiculum, whose shell possesses the most discernible coiling axes of any gastropod (four). 9 of 10 Croatian Cave Snails J. Bedek, Alexander M. Weigand / Wikimedia Commons This ghostly Croatian cave snail (Zospeum tholussum) was discovered deep in the Lukina jama–Trojama cave system — the deepest cave in Croatia and 14th deepest in the world — in 2013. Apart from being so recently described, it is also particularly noteworthy for being almost entirely transparent — even its shell. Because the see-through gastropods spend their entire lives in extreme darkness, they have no sense of sight. 10 of 10 Hairy Triton's Trumpets Dave C. / Flickr The most sinister-looking shell in the snail world might belong to the hairy triton's trumpet (Cymatium pileare), which resides in a spike- or "hair"-covered shell that juts off into a blunted point or "spire." Though it does have a rather voracious appetite, it's herbivorous and doesn't prey on other animals. Hairy triton's trumpets live in shallow water around coral.
