Patella ulyssiponensis Patella ulyssiponensis Patella ulyssiponensis, common name the rough limpet, or China limpet is a species of sea snail, a true limpet, a marine gastropod mollusk in the family Patellidae, one of the families of true limpets. Compared with the common limpet, "Patella vulgata", the rough limpet has a similar shell (maximum size 50mm long x 40 mm wide x 20 mm high, apex closer to the front of the animal/ anterior than to the back/ posterior) but with radiating ridges that are finer and which alternate 1-ridge/ 3-ridges around the shell in a distinct pattern. The interior of the shell
Composition of the human body are averages of different numbers reported by different references. The adult human body averages ~53% water. This varies substantially by age, sex, and adiposity. In a large sample of adults of all ages and both sexes, the figure for water fraction by weight was found to be 48 ±6% for females and 58 ±8% water for males. Water is ~11% hydrogen by mass but ~67% hydrogen by atomic percent, and these numbers along with the complementary % numbers for oxygen in water, are the largest contributors to overall mass and atomic composition figures. Because of water content, the human body
