A Microsoft wireless optical mouse. An optical mouse is a computer mouse which uses a light source, typically a light-emitting diode (LED), and a light detector, such as an array of photodiodes, to detect movement relative to a surface. Variations of the optical mouse have largely replaced the older mechanical mouse design, which uses moving ...
In addition to being weakly bioluminescent in blues and greens, comb jellies produce a rainbow effect similar to that seen on an oil slick, and which is caused by interference of incident light on the eight rows of moving cilia or comb rows which propel the organism. The comb rows beat sequentially, rather like the action of a Mexican wave. The ...
Cydippida is an order of comb jellies. They are distinguished from other comb jellies by their spherical or oval bodies, and the fact their tentacles are branched, and can be retracted into pouches on either side of the pharynx. The order is not monophyletic, that is, more than one common ancestor is believed to exist. [1]
Future comb jelly research. What Rodriguez-Santiago finds most interesting about the study is the way it calls into question what she thought of as “pretty hard boundaries” between self and other.
The comb jellies have more than 80 different cell types, exceeding the numbers from other groups like placozoans, sponges, cnidarians, and some deep-branching bilaterians. [ 23 ] Ranging from about 1 millimeter (0.04 in) to 1.5 meters (5 ft) in size, [ 22 ] [ 24 ] ctenophores are the largest non-colonial animals that use cilia as their main ...
The theory of evolution shows that all life stems from a single root and that we are related, more or less distantly, to every other living thing on Earth. More extraordinarily, if the first ...
