Sea Otters dive to the seafloor to obtain a variety of invertebrate animals. The most common prey of Sea Otters are sea urchins, mussels, abalone, clams, scallops, crabs, sea snails, chitons, octopus, and squid. An acute sense of touch, using paws, nose, and whiskers, is very important for finding prey in crevices or bottom sediments, and during dim light.
Who invented antimony? Antimony has been in use since the ancient Egyptian's used one its  minerals, stibnite (Sb2S3) as black eyeliner up to 5000 years ago.  Roman author Pliny described how heat â¦ ing this mineral formed what  he called lead. We now know that this was actually antimony.
High-energy photons, when they come near another nucleus, can spontaneously turn into an electron-positron pair (conserving charge and the number of electrons, which both add to zero since a positron has positive charge and is an anti-electron).he answer is yes, but it's not new news. Antimatter has been created in abundance by high energy cosmic rays and with past and current accelerators like Fermilab. The anti-electron, or positron, was postulated in1928 by Paul Dirac, and was observed in a cloud chamber by Carl Anderson in 1932.
