Edwardsiella andrillae is a species of sea anemone that uniquely lives anchored to the underside of sea ice offshore of Antarctica. It was discovered in December 2010 during a test run of an undersea robot by a team of researchers associated with the Antarctic Geological Drilling (ANDRILL) Program. The newly discovered anemone was named for the aforementioned program.^[2]

Description

According to the scientists, the anemones were less than an inch long when contracted, but would feature between twenty and twenty four tentacles and expand out to three to four times their original size when they relaxed. This includes eight longer tentacles placed in a ring around the inside of the animal, and twelve to sixteen on the outer ring.^[2]

Distribution

As of January 2014, the anemone has only been spotted under the Ross Ice Shelf.^[2]

Habitat

It is unclear how the species attaches itself to the sea ice, as it would be unable to conventionally burrow into it as other members of the family do in sand. It is the only known species of anemone to live in ice. Additionally, scientists are unsure of how the species survives the temperatures without freezing, and their methods of reproduction. It is speculated that the creatures feed on the plankton in the water.^[2]

Discovery

The

On 23 May 2014 International Institute for Species Exploration declared Edwardsiella andrillae as one of the "Top 10 New Species of 2014" among different species discovered in 2013, chosen for its unique habitat.^[3][4]
