Uncharismatic Fact of the Day

Siblings can be a pain-- especially when they're all clones of you. The aggregating anemone is often found in masses of up to a hundred polyps, all of them identical to each other. The ones on the edge of the mass are smaller and unable to reproduce, but have larger, specialized tentacles called acrorhagi that they use to defend their territory from invading anemone masses.

Sea Creature of the Day, July 7: The coolest sea anemone wants to remind you that you have 60 hours left to back the Be the Sea Kickstarter!

Please help us reach the final stretch goal, which adds foil artwork on the hardcover’s cloth cover and doubles the amount of Sea Creature postcards.

Thanks to all of you, we have achieved a better quality of hardcover, and a bonus story by Clara Ward!

An anenome in a crevice! Couuuld be a Green Anemone but can't say for sure. Though they may not look it these are predatory animals!

A predatory marine animalcrum of the order Actiniaria, named for the terrestrial (where else, hardly likely to be Martian) plant anemone because of the flower's colorful past.

Phylogenomics reveals coincident divergence between giant host sea anemones and the clownfish adaptive radiation.

The mutualism between clownfishes (or anemonefishes) and their giant host sea anemones are among the most immediately recognizable animal interactions on the planet and have attracted a great deal of popular and scientific attention. However, our evolutionary understanding of this iconic symbiosis comes almost entirely from studies on clownfishes- a charismatic group of 28 described species in the genus Amphiprion. Adaptation to venomous sea anemones (Anthozoa: Actiniaria) provided clownfishes with novel habitat space, ultimately triggering the adaptive radiation of the group. Clownfishes diverged from their free-living ancestors 25-30 MYA with their adaptive radiation to sea anemones dating to 13.2 MYA. Far from being mere habitat space, the host sea anemones also receive substantial benefits from hosting clownfishes, making the mutualistic and co-dependent nature of the symbiosis well established. Yet the evolutionary consequences of mutualism with clownfishes have remained a mystery from the host perspective. Here we use bait-capture sequencing to fully resolve the evolutionary relationships among the 10 nominal species of clownfish-hosting sea anemones for the first time. Using time-calibrated divergence dating analyses we calculate divergence times of less than 25 MYA for each host species, with 9 of 10 host species having divergence times within the last 13 MYA. The clownfish-hosting sea anemones thus diversified coincidently with clownfishes, potentially facilitating the clownfish adaptive radiation, and providing the first strong evidence for co-evolutionary patterns in this iconic partnership. http://dlvr.it/T1rZYz
