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! 😍
This gorgeous green nudibranchs was photographed by Chela Zabin in the Phillipines. #SeaSlugSquad

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!

Nuestro proyecto #cienciaciudadana#InvaderID acaba de ser traducido al español! Nosotros colaboramos con muchos científicos hispanoparlantes en Suramérica y Europa, y estamos super emocionados de difundir nuestro amor por los invertebrados a estudiantes alrededor del mundo.
Nuestra excelente voluntaria Luz Futrell tradujo al español todas las instrucciones para el proyecto en línea. Estamos muy agradecidos por todo su arduo trabajo para aumentar el alcance de nuestro proyecto y...

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.
We developed these for #BeringSeaDays 2019 in St. Paul, AK. Learn about the local fauna of coastal Alaska! #SciArt#scicomm
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!

We're going to #livetweet this event! Watch along with us here and send us your follow up questions.
#InvasionsLabPub Alert! @SmithsonianEnv scientist Erica Keppel led a new paper re-describing the sabellid tubeworm Parasabella fullo after our team discovered the first record of the #invasive worm on a ship hull in California. #WormWednesday#THREAD tandfonline.com/doi/full/10.10…
Parasabella fullo <pic> looks remarkably similar to native CA worm P. pallida, and lacked a comprehensive description or illustration to easily decipher between the two worms. By re-describing the species, we strengthen taxonomists’ ability to id the worm in non-native habitats.
Plastic can bring coastal animals with it when swept out to sea, like these anemones on a fish basket. This week, postdoc @LinseyHaram visited SERC-West to catalog a sampling of life #VortexSwim collected from plastic in the North Pacific Gyre. #InvasionsFlotilla (📸@ahaigh126)
Getting to the Gyre isn't easy, so we're grateful we could rely on the #VortexSwim crew, who collected the samples while following @BenLecomteSwim's epic swim from Hawaii to San Francisco—all to raise awareness about plastic pollution. (📸@ahaigh126)

This week's #GlobalAssessment on biodiversity warns that 1 million species face extinction due to human activity. Invasive species are cited as a main threat, as they move to new habitats, effectively tipping the scales & threatening native species. ow.ly/66GI50u6pKQ (1/4) #InvasiveSpecies are considered one of the most dangerous threats to marine ecosystems worldwide, second only to habitat loss. Since the 1900s, scientists have documented a 20% decline in native species due to their impacts! #FridayFactow.ly/IyuG50u6qdv (2/4)

The way people feel about a species is all about location, location, location! #BlueCrabs (Callinectes sapidus) are a delicacy in the Chesapeake. They're the most valuable fishery in the Bay, and every restaurant around claims to have the best crab cakes. #FunFactFriday
But in Spain, blue crabs are a problematic #invasivespecies. First observed in 2012, the crabs have spread throughout wetlands, estuaries and rivers. They're causing severe negative impacts to fishermen because the crabs cut through nets.

To wrap up National Invasive Species Week – let's explore one of our favorite invaders: Loxothylacus panopaei, the body-snatching parasite. #NISAW#ZombieCrabs (1/6)
The parasite, which is technically a barnacle, takes over a crab and turns it into a #ZombieCrab. Loxo infects and assumes control over a host crab, controlling major functions such as molting and reproduction as well as compromising the crab’s immune system. (2/6)

The encrusting #bryozoan (Watersipora sp.) is giving our taxonomists a headache! Through genetics, we've discovered what we thought was one species is actually MULTIPLE & they cannot be identified by morphological characters alone! #InvasiveSpecies#NISAW (1/6)
One species, Watersipora subtorquata complex, is wide spread as an #InvasiveSpecies across the globe. However, we have a poor understanding of its native region since it has been so often confused with several other species! #InvasiveSpeciesWeek#NISAW (2/6)

#DYK one of the most voracious ocean predators is the sea star? Most species are generalist predators, eating mollusks, crustaceans, bivalves, microalgae, and other echinoderms. Acanthasteridae, commonly known as the Crown-of-Thorns seastar, will even feed on coral polyps! (1/5)
The Northern Pacific sea star (Asterias amurensis) was named one of the world’s 100 worst #InvasiveSpecies. These stars will eat almost anything causing huge economic consequences – the Tasmanian fishing industry alone has suffered an estimated billion dollar loss! #NISAW (2/5)
In honor of our #ScientistsInTheField, for this week's #FunFactFriday we're exploring the impact of marine protections, like the designation of current #FoulingSurvey site Cocos Island as an UNESCO World Heritage Site in 1997 and as a National Park of Costa Rica!
Efforts have been made to preserve the natural ecosystem on and around Cocos. The only permanent residents are park rangers. All visitors (a few tourists and scientists) require permission to visit. No camping, agriculture, fishing, or businesses are allowed on the island.

It may be a #SnowDay for those of us at the main @SmithsonianEnv campus - but some of our researchers are enjoying rustic, tropical lab digs on Cocos Island, Costa Rica. Any ideas what book’s fictional island was based off of Cocos? HINT: 🦖🦕 #ScientistsInTheField
Did you guess #JurassicPark!? Michael Crichton's novel (and the subsequent movies) take place on the fictitious "Isla Nublar" of Costa Rica, which is modeled after Cocos Island! #TheMoreYouKnow

We study #invasivespecies & the issues that spawn when a newcomer joins an already balanced ecosystem. But we know that invasions don't always happen in a perfect system.
Ocean acidification will unbalance our coastal ecosystems and open a door to more invasions. #FunFactFriday
OA, which increases as CO2 is added to the ocean, can make growing calcium-based shells very difficult for young bivalves. Oysters, mussels, and clams might grow softer or smaller shells, leaving ample opportunity for better adapted invasive species to take their place.
