It's finally wildcard day for #SlugsVsFish #SlugsVsFishes!

One of the most amazing things about sea slugs is the diversity of morphology! Here's a thread of some the amazing shapes of nudibranchs our scientists have found in the field.

First up check out these colors! 😍 Bright blue nudibranch
This gorgeous green nudibranchs was photographed by Chela Zabin in the Phillipines. #SeaSlugSquad Green nudibranch with orang...
But what if you prefer stripes to one standard color? 🤔 A white and purple striped ...
Or spots? Nudibranchs have it all! A yellow and blue spotted n...
Now let's look at how different their body shapes can be! A blue nudibranch with curl...A light blue nudibranch wit...
Nudibranchs' cerrata can be in many different shapes, branched or curly, and different colors, some with shooting venomous nematocysts. A nudibranchs with spiky ce...
Or maybe intense cerrata aren't your favorite... Perhaps a more simple shape and color is to your style? A white Dorid nudibranch.A big white nudibranch.
Some sea slugs still even have a pronounced shell! A green sea slugs with a la...
Don't forget size! Even though these two are the same colors, the one on the left (on a bryozoan colony) is many times smaller than the one on the right (in a sandwich Tupperware). A small black and yellow nu...A large black and yellow st...
Basically what we're saying is that you never know what to expect when you find a sea slug. And that is part of the joy of finding them!

This species is Bulla gouldiana from Palos Verdes, CA. It is a type of bubble snail.
This nudibranch is Doris cf. kerguelensis, and was photographed in Antarctica!
Photographed on a dive in Monterey, CA, we think this one is cf. Dendronotus iris.
This bright blue nudibranch is Doris pecten from Maui, HI!
This is Antiopella fusca, formerly called Janolus fuscus.

Eek! We've been so busy studying the two biggest estuaries in the US, we almost forgot about #EstuariesWeek
As part of the #FoulingProject we are collecting samples from marinas around both #ChesBay and #SFBay scientist sitting on a dock...scientist sitting on a dock...
We then take them back to the labs at @SmithsonianEnv and #SERCWest @EOS_Center and process the panels with a coarse identification of the invertebrates that settle on them and take vouchers and samples for DNA analysis.

Depending on location in the bay, the panels can look very different and contain different assemblages of organisms. #InvertebratesRule #FoulingProject #EstuariesWeek #ChesBay fouling panel with barnacle...fouling panel with encrusti...

Please help us welcome our 2020 #intern class! Some of the class is virtual, focusing on coding and data analysis, while a few of our interns will be able to do limited socially distant #fieldwork.
First up is Rémy Barbiéro! Rémy is a rising senior at @Occidental, and will be working on the #ZombieCrabs Project. Rémy will help create a #CitizenScience project on @the_zooniverse to count parasitized crabs from Chesapeake Bay. Welcome! Intern Rémy Barbiéro in the...
Time to meet another of our amazing summer #interns

Welcome Tyler Kempton! Tyler is a local high school student who is working on using #R to prepare an analyze data from our #InvaderID project. He works with the @SmithsonianEnv Citizen Science department. Tyler stands on a rock by t...

Our #citizenscience project #InvaderID on @the_zooniverse has just been translated into Spanish! We collaborate with many Spanish-speaking scientists in South America and Europe, and we're excited to spread the invertebrate love to interested students around the world!
Our amazing volunteer, Luz Futrell, translated all the instructions for the online project into Spanish. We are so appreciative of her hard work to increase the reach of our project and are amazed by all the wonderful work done by volunteers on this special research.
To view the project in Spanish, follow the link to Invader ID below and look for a tab to switch languages at the top menu.

#InvasionsLabPub Alert! @SmithsonianEnv scientists Brenda Soler-Figueroa led a paper on the characteristics of global port phytoplankton and their implications for current #BallastWater regulations @sciencedirect #Thread
ow.ly/2fHi50zE29S
1/4-Thirty-one major ports in the Northern Hemisphere over a wide range of latitudes and salinities were selected to evaluate: a) how natural communities compare to challenge requirements and b) the abundance of unregulated size fractions. #BallastWater #PlanktonSampling #Thread Map of port sampling locati...
2/4-Phytoplankton <10 μm comprised over 80% of total abundance and yet are unregulated. Some of the organisms in this size class pose serious threats to ecosystem, fisheries and human health. #BallastWater #PlanktonSampling #Thread Average and percent composi...

Are you looking for some low stress #RemoteLearning activities this Friday? How about some #ocean #invertebrate coloring sheets? 🌊🦀

We developed these for #BeringSeaDays 2019 in St. Paul, AK. Learn about the local fauna of coastal Alaska! #SciArt #scicomm A coloring sheet featuring ...
Use the sheet to do a hunt! Do you think you can match all the names to the pictures? 🔎🐚

Post below if you think you know who is who! We'll post the answers on Monday! Image
Or, if you're looking for a simpler option, learn three new ocean animals and color them!

Animals use colors to show predators that they are poisonous - how do you think that would look?
