From Wikipedia, the free encyclopedia. In behavioral finance, the ostrich effect is the attempt made by investors to avoid negative financial information. The name comes from the common (but false) legend that ostriches bury their heads in the sand to avoid danger.
Jellyfish have cells called cnidocytes, which contain nematocysts, and located on their tentacles and on their manubrium.Whenever a predator comes in contact with cnidocytes, hundreds to thousands of cnidae (filaments of the nematocysts) are ejected in the predator's direction.one ostriches have been known to kill lions with their kicks. ostriches protect themselves by lying very close to the ground â¦ in an attempt to hide. If this doesn't work they will use speed to run from predators. It is not true that they bury their heads in the ground.
