The Moon Jellyfish, or Aurelia aurita, are boneless, heartless, brainless, and made most entirely of water and relatives of the Portuguese man-of-war, other siphonophores and Donald J. Trump (except for the bone thing). The Moon Jelly's color can change depending on its diet. If the jelly feeds extensively on crustaceans, it turns pink or lavender. An orange tint indicates that a jelly's been feeding on brine shrimp. It's clear the Donald variety of Moon Jelly has been munchin' exclusively on shrimp cock...tail.
A new super neat study says that when a juvenile loses tentacles it rapidly reorganizes its remaining limbs to maintain symmetry through a repeated contraction of muscles that the jellyfishes use continually. Wow, how neat is that?
Finally, Moon Jellies are out of this world, or have been. About 2,500 moon jelly polyps and ephyrae—two early stages in the jelly life cycle—went into orbit aboard the space shuttle Columbia in May 1991 studying the effects of weightlessness on development of internal organs in juvenile jellies. My brain is literally about the explode thinking about neat little moon jelly bros and bras floatin' around in Space. How neat and freaky is that?
