• Ensis
  • These mainly included the mussel Mytilus platensis and the ribbed mussel Aulacomya atra (Mytilidae), the Puelche oyster Ostrea puelchana (Ostreidae), the "geoduck" Panopea abbreviata (Hiatellidae), the razor clam Ensis macha (Pharidae) and the venerid Leukoma antiqua and Amiantis purpurata clams.

  • The proboscis is everted (turned inside out) and the lower half of the Atlantic jackknife clam (Ensis directus) is enveloped. (wikipedia.org)
  • sediment
  • The three variables, water temperature, clam size, and sediment particle size were highly significant (1% level), in influencing clam reburial activities by the end of the second hour through the termination of the experiment 48 hours later. (naver.com)
  • In an effort to escape, the clam works its way out of the sediment and may then be at risk of predation by birds. (wikipedia.org)
  • abundance
  • It is not clear whether the ribbonworm preys on hard clams, but a high abundance of this worm at one location near Prince Edward Island was thought to be responsible for the high mortality among newly transplanted hard clams. (wikipedia.org)
  • experimental
  • Optimum water temperatures for reburrowing were between 8.8 and 21 C. After 48 hours, 62% of the small, 39% of the medium, and 21% of the large clams had reburrowed in all experimental tests combined. (naver.com)
  • size
  • The aquarium with less than 0.5 mm substrate particle size had the greatest percentage of reburrowed clams of each size. (naver.com)
