YouTube video by Todd Snider - Topic Enjoy Yourself

Sad to learn that Todd Snider, one of my very favorite folk singers, died last week. I am grateful I got to see him play several times. I found out from an email saying that the concert I bought tickets for had been cancelled...

Here's my favorite recording of his: youtu.be/3RWAuSdQWoM?...

Exciting! I am teaching about this very topic tomorrow morning. I guess I should read this paper tonight!

One of my favorite animals to find in the hydroids are Pycnogonids, aka, sea spiders. We had a real treat today because we found one carrying eggs. In sea spiders the males carry the eggs.

These are from a wild collection. I do run field trips for my lab, but the hydroids live a little too far away for us to visit during a lab period. (This is also a bit of a double dip for me because some of my students have a research project with one of the nudibranchs).

A brittle star with six arms. Half of the arms are very small because they are regenerating. The arms have brown stripes.

Next up a six armed brittle star! This one is in the process of regenerating half of its arms. Does anyone know the ID? I would love to figure out this one.

My research microscope needs repairs, so I am trying out some alternative methods for my photos. This isn't my best work, but I am having fun with it and these critters are too cool not to share.

Today in my Invertebrate Zoology course we are doing one of my all time favorite labs where we search through hydroid colonies to find macroinvertebrates. Here are some of my favorite finds from today!

First two hydroid feeding nudibranchs! IDs in alt text.

Spiders and Springtails Underwater …what’s next? - UF/IFAS Extension Franklin County Who would ever imagine spiders living underwater on an oyster reef? Believe it or not, they do. The tremendous productivity of our Gulf coastal waters has made them important to humans throughout hist...

I am think these are Paratheuma insulana and they feed on tiny springtails that also live on the oyster.

We found oyster spiders today during my oyster lab field trip for my Invertebrate Zoology class! These are marine spiders! They have special setae (hairs) that trap air and let them live underwater. #invertebrates #spider

Okay, I knew about the carcinoecium. But, I did know it evolved more than once! Convergent evolution is so cool!

Since sea hares are hermaphrodites this is also the ideal female body. This is the ideal body.
