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
A marine spider, Paratheuma insulana, on an oyster shell. The spider is brown with some darker brown stripes. The oyster shell is mostly white with some dirty yellow/brown edges. A marine spider, Paratheuma insulana, on an oyster shell. The spider is brown with some darker brown stripes.

Some lovely nudibranchs for #seaslugday. These photos are from this summer when I was scuba diving in Komodo National Park, Indonesia. #invertebrates 🦑
An orange cladobranch nudibranch with white tips on rhinophores and tentacles. The slug has a white stripe on the body and some blue dots at the tip of the cerata. It is sitting on an orange sponge. A dorid nudibranch sea slug. The slug has a cream yellow mantle skirt with a thin black edge. The foot is white. The gills, center of the slug and rhinophores are orange. There is a wavy black line around the orange part of the center of the slug's body. A very colorful dorid nudibranch. The slug has a brown body with orange stripes. The gills and rhinophores are bright orange. There are also some yellow and blue areas around the head and tail. An adorable white dorid nudibranch.

After several attempts I bought some concert tickets from AXS. It is mindboggling that they have managed to make an app and website that is somehow worse to use than Ticketmaster. It's criminal that these companies charge us "convenience/service" fees on their janky apps.

We had one of my favorite crabs in the invertebrate teaching lab today! This is Dromidia sp. a carrier crab. Their last pair of legs is modified to carry sponges and other animals as a defensive mechanism. This one is carrying a colonial tunicate. #invertebrates 🦑🦀

Two for one invertebrates for #InverteFest. Here is the nudibranch Hypselodoris tryoni, in Komodo Indonesia, where you can see the purple eggs of a parasitic copepod sticking out from the slug's gill pocket.

Last night the state of Florida painted over the crosswalk at the Pulse nightclub memorial in Orlando under the guise of road safety. They claim that rainbow crosswalks are distracting to drivers.

One of my favorite snails, the velutinid Coriocella nigra! Velutinid snails have an internal shell so they often get mistaken for slugs or other organisms. I saw this one while scuba diving in Komodo National Park, Indonesia last month. #molluscmonday #snail #invertebrate #komodo #indonesia 🦑
A photograph of the velutinid snail Coriocella nigra. The snail does not have a visible shell because it is covered by the mantle. The snail is velvety black green in color and has five large lobes on the dorsal side plus a siphon sticking forward which looks similar to the lobe. The snail is sitting on some red calcareous algae next to some orange coral polyps which are retracted.

This hermit crab may have been a bit ambitious with the choice of shell. #hermit #crustacean #invertebrate #Indonesia #Komodo 🦑 🦀

I've got another new paper out this week, this time in Symbiosis! In this paper we use DNA barcoding to describe the diet of the sacoglossan sea slug Elysia diomedea from the Gulf of California, Mexico. Read it here: rdcu.be/ezcoD
#sluglife #invertebrates #slug #academicsky 🦑🧪
The sea slug Elysia diomedea. The slug is green with some white spots on the body. The parapodia are quite ruffly with some yellow around the edges. The rhinophores of the slug have black and yellow stripes running from the tip towards the eye of the slug. The eye is a small black dot on the head. The slug is sitting on a mixture of red algae.

Recently got back from an amazing trip to Flores, Indonesia with @elizabeth-in-fla.bsky.social. We had some fantastic scuba dives and got to see some wild Komodo dragons! They are so cool! #indonesia #komodo #dragon

The photo on the left, labeled A, is a lighter green color and is the specimen from Tampa Bay. The one on the right labeled B, is from Massachusetts, and is a darker color green. There is a 1cm scale bar on the image.

Look at the colors on these sea slugs! These must be the most colorful lettuce slugs, Elysia crispata, that I have ever found. I ran across these two on a dive in Roatan, Honduras while I was there teaching my Coral Reefs course. #sluglife #invertebrates 🦑
A very colorful lettuce sea slug, Elysia crispata. This slug has frilly parapodia that are white at the tip followed by a red band and then a yellow band. The body of the animal is green, but parts of it are blue and it also has some large white and yellow spots. The slug is sitting on some limestone on a coral reef.

I'm in Roatan, Honduras teaching my Coral Reefs class. Yesterday my students took part in some of the coral restoration efforts by cleaning the coral nursery and outplanting a few coral colonies. Today is their underwater lab practical exam. I love getting students underwater and into the field!
