在此次的潛水調查中,發現了2種潛在的新種海葵。海洋生物學教授,同時也是這次潛水探險隊隊長的朱伊特(Stephen Jewett)教授表示,這些是「會走路」或是「會游泳」的海葵,因為他們會沿著覓食的路線在海底慢慢移動。

通常大部分的海葵都是固定生長於海底,而「會游泳」的海葵則可以隨著海流移動漂流,這些海葵的體型從壘球到籃球的大小都有。

New Marine Species Found in Alaska's Aleutian Islands

This year's dives surveyed the western region of the Aleutians, from Attu to Amlia Island, while last year's assessment covered the eastern region.

During the dives, two potentially new species of sea anemones have been discovered. Stephen Jewett, a professor of marine biology and dive leader on the expedition, says that these are "walking" or "swimming" anemones because they move across the seafloor as they feed.

While most sea anemones are anchored to the seabed, a "swimming" anemone can detach and drift with ocean currents. The size of these anemones ranges from the size of a softball to the size of a basketball.

Another new species is a kelp or brown algae that scientists have named the "Golden V Kelp" or Aureophycus aleuticus. According to Mandy Lindeberg, an algae expert with NOAA's National Marine Fisheries Service and a member of the expedition, the kelp may represent a new genus, or even family, of the seaweed.
