My first visit to the National Aquarium was also a behind-the-scenes tour of the jellyfish room with Jennie Janssen (@JellyJanssen). I was completely mesmerized by hundreds of jellies in various industrial-sized aquaria. But I should also note, I am frequently mesmerized by jellies, big and small, be they in an aquarium or under the scope… Continue reading So many jelly photos!
A couple of weeks ago, New York Times’s science writer Carl Zimmer wrote about a recent review of Hays et al (2018), which asked: how important are jellyfish in marine ecosystems?

Nematocysts are thread-like capsules secreted by stinging cells that are… Continue reading Stinging Cells from the Summer!

The species… Continue reading Species spotlight: Egg Yolk Jellies

Sea nettles have that stereotypical look that the word “jellyfish” most folks conjure up in their mind: large, round bell, tentacles coming out from the edges and semi-transparent with… Continue reading So When You Say Jellyfish?
