OK... CRAZY IDEA. Who's bored right now? Maybe you're back at work (like me) but not necessarily motivated to start anything new?


Our #citizenscience project is only 250 IDs away from being done (out of nearly 100,000)!
@echinoblog @SpinyDag @alisonkestrel @jebyrnes @NMNH @mccullermi @mariavsharova @bmtracy This is not a drill. Who ever is out there - we're so close! Image

Today on our #citizenscience board we're discussing which inverts are easiest to ID from photos. Our recent #InvasionsLabPub showed that conspicuous taxa (large or arborescent) are best. Do you agree? Try yourself & let us know which animals you recognize fastest! #FunFactFriday Image

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. (1/4) Image
#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! #FridayFact (2/4) Image
Scientists say #InvasiveSpecies impacts will worsen as climate change allows shipping routes to open in places like the Arctic. They predict international shipping could increase between 240% & 1,209% by 2050 – creating new travel routes for many #HullFouling organisms. (3/4) Image

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 SERC researcher holds a blu...
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. A bushel of blue crabs.
Researchers from the University of Alicante Marine Research Center in Spain are working with fishermen to develop ways to control the expansion and minimize impacts on local fisheries.…

ICYMI, our #FunFactFriday is about new research from us, @DarwinFound and @WilliamsMystic - Scientists found >50 new non-native species in the #galapagosislands! But we're not shocked that there are new species, non-natives are everywhere! Invasive Bugula on a foulin...
However the number that we found (10 times what we previously thought) was surprising.

Part of the reason that this was such a surprise was that it had been nearly 30 years since the last comprehensive sampling (see photo!) of fouling organisms on the Islands. SERC scientist Linda McCann...
This is a huge part of why we started the #InvaderID project on @the_zooniverse. By increasing the speed and frequency with which we can track new invaders, we have a better chance of detecting the invasion while in its early stages. You can try it here:…

For today's #FunFactFriday we're featuring an invertebrate that also celebrates #InternationalWomensDay - the slipper limpet!

(they're the gastropods on this gastropod and the gastropod on the gastropod on the gastropod) Three limpets sit atop a sn...
Slipper limpets reproduce by stacking themselves on top of each other like a jenga pile. Interestingly slipper limpets can change sex depending on which level of the pile it lands in. The limpet on the bottom of the stack will change to the female sex. Limpets in a pile.

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) Image
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) Image
Loxo can take over at least 9 different kinds of crabs – including the white-fingered mud crabs in the Chesapeake Bay! #NISAW #ZombieCrabs (3/6) Image

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! Map of Cocos Island
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. View of a waterfall from a ...
Despite these extraordinary efforts, the island still faces damage from #invasivespecies. No mammals are native to the island, but deer, wild boar, cats and rats have been introduced. We're there trying to understand how invasive marine species are impacting the ocean ecosystem. SERC scientist examines a f...

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.
There are many more ways OA can hurt coastal systems. It might reduce the amount of food available from zooplankton, increase the growth of harmful algae, or even potentially dissolve carbonate structures. Any of these changes might cause unpredictable ecosystem breakdowns. Image

We use many methods to find #invasivespecies: intertidal searches, settlement panel projects, & plankton tows.
You might not know each method can find the same species, rather than each looking for different species! #FunFactFriday We're exploring invertebrate planktonic phases!
The animals that settle on our shores can spend some portion of their life floating in the ocean. We call this part of their life the #planktonic phase, and depending on the species it defines how far a population can spread.
Some adult tunicates, like salps, spend their whole lives swimming in the open ocean. But most tunis we study are benthic (attached to the shore) as adults, so spend only a small period swimming as larvae. Here's a new tuni tadpole, just released from a Botryllid on our panels. A tunicate tadpole, which h...

#DYK some of the animals that live on our #FoulingProject panels are too small to see with a naked eye? For example, encrusting bryozoans live in small "cells" that group together to form circular discs with intricate designs. (1/3) Image
Each of the bryozoan cells - or zooids - contains an animal! All the zooids are clones of the original "ancestrula" zooid. Here's an example of a close-up photo of what an encrusting bryozoan looks like. #FunFactFriday #UnscienceAnAnimal (2/3) Image
Bryozoans can be ID'd by the color, shape, and size of the zooids, as well as the shape of the hole they use to emerge from to grab floating food. You can try to find bryozoans on our panels by checking out our #CitizenScience project: (3/3) 🔬 #InvaderID

#FunFactFriday on #biocontrol: We focus on finding new #invasivespecies & preventing introductions b/c #eradication, especially in the ocean, is hard. Removing small animals by hand is almost always impossible, so sci's must use a mechanical, chemical, or biological solution. 🔎
Introducing known predators of invasives is an effort called "biocontrol" but sometimes these predators don't follow orders. Check out this @SmithsonianMag article about a wasp that *might* save Florida oranges!
A well known biocontrol failure is the introduction of the South Am. Cane Toad to AUS 🇦🇺. It was brought to eat an insect pest but the toad didn't like the habitat of the pest & moved quickly to a new area, where its population exploded - a problem since cane toads are poisonous!

Are you interested in learning more about coastal marine animals? We're launching a new #CitizenScience project! #InvaderID 👨🏾‍💻 Image
Yesterday we hosted 2nd beta-test of new @the_zooniverse project. Dedicated @SmithsonianEnv volunteers tested an ID game anyone can play @ 🏡 ImageImage
@the_zooniverse @SmithsonianEnv If the project gets approved - we can monitor coastal communities on a much larger scale than our #FoulingTeam can travel to every year. 😂✈️
