Stung by a Moon – Celebration of the Aurelia aurita genome

On 3 December 2018, the first jellyfish genome was published online at Nature Ecology and Evolution. To be clear, the is the first genome of a cnidarian with a jellyfish stage (i.e. medusa). What was the lucky species? Aurelia aurita (species 1 complex), the Moon jelly. Moon jellies are a commonly encountered species around the world, and probably one of the first jellies most

I was completely mesmerized by the hundreds of jellies in various industrial-sized aquaria. I am frequently mesmerized by jellies, big and small, in an aquarium or under the scope in the lab. And I take a lot of pictures. I

The answer: important. In fact, probably more important than we have been giving them credit for. Jellyfish (often referring to both cnidarians and ctenophores) have typically been considered trophic

Stinging Cells from the Summer!

I am busy cranking away at the Smithsonian NMNH, but I wanted to share some photos of one of my favorite complex animal features: the stinging cell! Stinging cells house nematocysts, the stinging cell organelles distinctive to all cnidarians (hence the Latin translation, nettle-bearing animals). Nematocysts are thread-like capsules secreted by stinging cells that are mechanically or chemically discharged through

Lives of Jellies at the Mall!

In the 95F heat, jetlagged, and arriving in DC less than 24 hours prior, I cannot describe how happy I was to do a little jellyfish outreach with the interns and researchers of the National Museum of Natural History (NMNH) Invertebrate Biology Aquaroom at the Annual Smithsonian Staff Picnic! Along with Dr. Allen Collins, Dr. Cheryl Ames, and interns Christine,
