@MHowell @FlockOfCats clams do clammunicate, through pheromone signals and sometimes even by living close together to feel each others' body language. If one clam closes the others know a threat is nearby! #clamFacts

Blue and green are rare colors for shells (and rare across life in general). A new study finds blue shells may be due to carotenoid pigments, while green is due to structural coloration! https:// www.nature.com/articles/s41598-026-61670-9 #clamFacts

@anubis2814 yes, depends on the species and area, but sometimes bivalves help bury carbon through their ability to grab particles and spit them out as pseudofeces, causing them to become a net sink for carbon! #clamFacts

The global bivalve trade is growing almost 10% a year. Challenges include harmful algae, pollution, invasive predators, and diseases, but overall, bivalves are a highly sustainable source of protein! Check the Monterey Seafood Guide to be sure, but many bivalve fisheries worldwide are stable and generally very low carbon footprint #clamFacts https://www.fao.org/in-action/globefish/news-events/news/news-detail/bivalve-trade-expands-despite-on-going-challenges/en

A new study found that when they sense parasitic flatworms in their vicinity, mussels stop filtering to avoid infection. Even more interestingly, they also stop filtering when they detect periwinkles that are an intermediate host for the flatworm. "Oh God, those filthy periwinkles are back, everyone clam up!" #clamFacts

@RussellsBarbershopQuartet a shell is a biomineral with an organic protein matrix! So it is a rock, an organ and a work of art all in one! #clamFacts

@llewelly scallops have some of the most centralized nervous systems of bivalves. They aggregate to mate at certain times of year. They can watch a screen of plankton go by and show signs of increased feeding activity, like us salivating at the Food Channel. They are mesmerized by certain wavelengths of light. They recognize different predators and respond differently to each. They have a lot going on in those nervous systems! #clamFacts

When you hold a shell to your ear, your ear hears the resonation of thousands of environmental noises. But your brain hears the sea. Our ocean is the resonator of our planet. Your brain is right. #clamFacts https://en.wikipedia.org/wiki/Seashell_resonance?wprov=sfla1

@FaithfullJohn re-replying so it can be seen publicly...
according to Williams 2016, "The red fluorescence is a useful character to identify porphyrins, as red fluorescence of non-porphyrin molluscan pigments is rare." I think all that you pictured can be found shallowly/intertidally where UV is more present, (Gibbula more frequently than the others I think, though I'd have to review), so could experience UV in life. Comfort 1948 observed the same thing you have, John, that the fluorescence is only seen in the top whorl for Gibbula. Perhaps it relates to a porphyrin the snail only expresses early in life. Williams observes "porphyrins are
often associated with red, brown or purple shell colouration". It does seem to overlap with the brown color they have at the protoconch in your pic, so I wonder if in this case it is a coincidental property of the porphyrin pigment they use for shell coloration as juveniles. Either way, seems like a lot of research to be done on the evolutionary purposes of shell fluorescence, if any! #clamFacts -

The Po River Delta in Italy was a huge Manila clam fishery in the 20th century. The clams are native to Asia as their name suggests, but they thrived in huge numbers in coastal lagoons of the Po estuary. They became a huge part of Italian cuisine. Recently, clam harvests have declined 70% due to the introduction of Atlantic blue crabs, which have taken well to the Adriatic and exploded in population, merrily eating the clams by peeling their shells open. One invasion after another, but so far blue crab has not been adopted as a staple in Italian cooking, partially because of their horror at the loss of the clams. I get it! #clamFacts https://www.ctvnews.ca/climate-and-environment/article/an-american-blue-crab-took-over-italian-lagoons-now-fishers-are-looking-for-new-careers/

Giant clams love light. As a general rule, the more light they can get for their symbiotic algae, the better. Some species will even continue to photosynthesize in air for hours exposed by the tide, since their photosynthesis provides them some oxygen. Which makes the "devil clam" (Tridacna mbalavuana) from Tonga and Fiji so weird. It lives up to 100 ft down! The super clear waters where it's found allow it to live as a kind of counterpart to mesophotic corals, which are able to photosynthesize even far from the sunlit surface. Since they are so rare, the devil clams are not well studied, but researchers determined it is able to compensate for its very deep lifestyle through some of the greatest photosynthetic efficiency known from giant clams! #clamFacts https://www.inaturalist.org/taxa/479982-Tridacna-mbalavuana

Clams can integrate all sorts of toxins from the phytoplankton they eat. Some prominent marine ones include paralytic shellfish poisoning, amnesic shellfish poisoning, and diarrhetic shellfish poisoning. There are dozens of known toxins around the world. In freshwater they can accumulate microcystin, which damages the liver. Before collecting clams for eating, always check for warnings from the local water quality or public health agency! #clamFacts

@Virginicus great question! Yes, freshwater mussels draw down both nitrogen and phosphorus through their filtering and carbon burial activities. This is both through direct assimilation of phosphorus in their tissue and buried feces, as well as by encouraging denitrification in the sediment, which turns nitrate back into N2 gas! #clamFacts

Psst...clams already provide us with tens of billions of free nitrogen removal services a year, and that's just a fraction of their power. If we helped them more through active aquaculture, we could cut nitrogen pollution from farming by about half! #clamFacts
