Two New Species of Anemones Discovered

June 27, 2013 – 01:19 pm

The species belong to the genus Neozoanthus, which was previously known only from a single species in the Indian Ocean. Surprisingly, the new species were found in the Pacific Ocean, in southern Japan and on the Great Barrier Reef, Australia.

The only previous species of Neozoanthus was described in 1972 from Madagascar, and subsequently it was not seen for almost 40 years, until recent research had ascertained that new Pacific specimens likely belonged to Neozoanthus.

The members of the Neozoanthus genus are small, with individual polyps no more than 6 mm in diameter, and have red, gray, blue or purple oral discs; all inhabit coral reef ecosystems in areas with strong currents and some siltation. Both new species and the species from Madagascar contain symbiotic, photosynthetic, single-celled algae that can provide them with energy from the Sun.

“We were very surprised in 2008 to discover Neozoanthus in the Pacific, in Japan, and initially thought that perhaps these were very rare, ” said Prof James Davis Reimer, lead author of a paper reporting both new species in the journal ZooKeys.

However, further research in southern Japan revealed that the Japanese species was locally common. A further surprise came during the Census of Marine Life’s Census of Coral Reef Ecosystems surveys on the Great Barrier Reef in 2009 and 2010, when similar encrusting anemones were found thousands of kilometers away from both Madagascar and Japan.

“These findings can be explained by the fact that there are very few zoanthid researchers in the world. These species are not particularly hard to find, but there was no one looking for them, ” Prof Reimer said. “This research demonstrates how little we know about marine biodiversity, even in regions relatively well researched.”

I learn the hard way, unfortunately

I don't just go to class, I test and learn in the field. Because I though I knew better, I figured I could bend the rules.
In fall four years ago I sheet-mulched over a bed full of Agapanthus and Japanese Anemones. I spread a 5 inch layer of compost (two strikes) over newspaper. We'd spread compost (in a one to two inch layer) over a client's soil for years as a sort-of "mulch." What could go wrong?
Although I carefully covered the soil, the Anemone had already reached the bed's perimeter and enmeshed itself amongst the Box edging. I cut down and dug out as much of the Agapanthus as I could before I sheeted
