Petroleum jelly in one patient. However, petroleum jelly is used extensively by otolaryngologists—ear, nose, and throat surgeons—for nasal moisture and epistaxis treatment, and to combat nasal crusting. Large studies have assessed petroleum jelly applied to the nose for short durations to have no significant side effects. Historically, it was also consumed for internal use and even promoted as "Vaseline confection". Most petroleum jelly today is used as an ingredient in skin lotions and cosmetics, providing various types of skin care and protection by minimizing friction or reducing moisture loss, or by functioning as a grooming aid, e. g. pomade. By reducing moisture
Jelly-falls can lead zones around jelly-falls to become hypoxic and inhospitable to larger scavengers. Researching jelly-falls relies on direct observational data such as video, photography, or benthic trawls. This means that jelly-falls are not always observed in the time period in which they exist. Because jelly-falls can be fully processed and degraded within a number of hours by scavengers and the fact that some jelly-falls will not sink below 500m in tropical and subtropical waters, the importance and prevalence of jelly-falls may be underestimated. Jelly-falls Jelly-falls are marine carbon cycling events whereby gelatinous zooplankton sink to the seafloor and enhance carbon
