The front legs of a bat include large webbed, spooky-looking wings, but describing them as such is the fault of all those ridiculous horror movies and television shows that portray vampires and Draculas in this fashion. Other mammals described as having the ability to fly are simply only gliding for short distances. After that process, those fertilised eggs, now known as spats, either sink down into a suitable site on the sea floor, or attach themselves to other places such as mature oyster mantles nearby, and begin to develop.īats are the only mammals capable of long distance flying. She releases these into the water, where the father's sperm, floating hopefully nearby, attaches itself to them. Wow, this is amazing: A single female oyster usually produces one hundred MILLION eggs every year. Oysters create their pearls by covering an intruder - such as a grain of sand - that has made its way past the mantle into the soft insides, with a protective layer of nacre, and then successive layers of that lovely substance are added to this over time, until the perfect translucent pearl has formed. References state that the largest pearl oyster is about the size of a dinner plate.

Pearl oysters are the creatures that produce the much sought after valuable gems, and these creatures can grow to a rather impressive size. Don't get excited though, for most of those created are worthless. Oyster is a name given to any member of the family of clams and molluscs, and, interestingly, most of these have the ability to produce a pearl. The family lives in saltwater environments, where, if they're wise, they'll keep a wary eye out for humans who consider slurping down the slithery creatures that reside within their hard protective mantles a great delicacy (shudder). Mr and Mrs Oyster have children known as spats.
