...bial mat that blanketed the floor periodically and protected thesand below from any disturbances above. The ancient worm-like animals may havemigrated through the sand just below the mats, using them as a source for foodand oxygen since the water within the sand layers was probably "reduced," orpoor in oxygen.......through 1997, sea otter numbers were stable in the protected Clam Lagoon, whilein the adjacent Kuluk Bay they declined by 76 percent. According to calculations based on the team's observations in one section of theAleutian Islands, killer whales must have killed 6,788 sea otters per yearbetween 1991 and 1997 t...Ohio State Professor Receives Patent For Infectious Bursal Disease Virus Detection Kit
