The disco clam is an aptly named creature that appears to be generating electricity in pulsating waves. It gives off the appearance of a light show that is mesmerizing and fascinating to watch. The light comes from thin bands along the outer surface of the clam when it is open.
But the truth is that the clam does not generate electricity, and it does not even generate light. This is not an example of bioluminescence. The thin bands are reflective tissue that are merely reflecting the light that is already present. The clam is able to expose and hide the thin band of reflective tissue very quickly. These tissues consist of nano-spheres made of silica. The appearance that this presents is reflection of light, alternating with red tissue in a rapid fashion. To the human eye, or the eye of a predator, this appears to be flashing light or even electricity that warns the predator to stay away and avoid contact.
The clam is able to reflect sunlight, or lights from a scuba diver's camera. This is an incredible and unique adaptation that is very effective as a survival tool. Nature provides many creatures of the ocean with the tools to create a defence. The variations of these mechanisms inspire awe and wonder. There are more mysteries in the ocean than we have answers for.

Help me its my first video so like and share it plz Raven is a big puppy with a big attitude and a big appetite. She has just been fed a big dinner, but her big stomach is still growling in a big way. Her owners have just sat down to their dinner and Raven can smell it. She gets the odd treat here and there but she is never fed from the table. She should know that she won't be getting any steak or potatoes, at least until the human dinner time is over, and only from her dish.
But Raven is a saucy dog and she complains loudly about the house rules. She reluctantly listens as she is told to distance herself from the table and the food, but she insists on not being forgotten as each bite is taken. A slight head nod, or even a raised eyebrow will make Raven jump back because she knows that the table food is off limits. She nudges Kristy with her nose with such enthusiasm that Kristy is knocked back slightly. Great Danes don't know their own strength and they seem to lack understanding of their size. Her attempt at a gentle nudge is anything but gentle.
Raven's owners adore her and she gets treated like true family. She is treated to free runs in the nearby forest almost every day. She has her own couch to stretch out on and she has an oversized dog bed by the fire when the winter comes. She gets to share the king sized bed and she has a whole bench seat in the family van. Great Danes are enormous and they are more than a handful, but they are endearing and fiercely loyal. Anyone who has ever owned one has fallen completely in love with these gentle giants.
