Thanks for visiting! A few years back, I briefly covered a throwaway Yahoo! article about how âcarbs will make you lose weightâ because so many readers had emailed about it. It turned out that the âcarbsâ in the article were resistant starch, a type of carbohydrate that our digestive enzymes cannot break down.

Prehensile tails acts like a fifth limb. Monkeys are the most famous creatures with prehensile tails and many tourists on safari have realized this a few moments too late after things vanished before their eyes. Most other animals have non-prehensile tails. source: Kirill Kurashov/shutterstock.com.
Chordata-Vertebrates, Tunicates, Lancelets. At some point, all of the organisms in this phylum have a structure called a notochord. A notochord is a flexible rod-like cord of cells that provides the main support for the organism's body during its embryonic stage.n some primitive species, the slits are used to filter food out of the water. In other species, like fish, the pharyngeal slits have gills. In other species, like mammals, the pharyngeal slits are only present during the embryonic stage. Chordates also have a dorsal nerve cord that runs down the length of the organism.
