@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

The Japanese littleneck or Manila clam (Ruditapes phippinarum) is a widely eaten and well traveled clam native to Asia that has spread to Western N. America and Europe via the aquaculture industry. A recent study confirmed from iNaturalist observations that it is now on the American East coast, giving it a global home run of invasions. In SF Bay these are quite common in the muddy intertidal. They burrow shallowly under the sand but are otherwise completely unpicky about where they live, which is part of why they're so happy to be transported to new places by us! #clamFacts

Once zebra or quagga mussels get into a water body, it is very difficult to remove them. Many common molluscicides like copper or chlorine are also very harmful to other life forms. Pseudomonas fluorescens strain CL145A is a bacterium that produces a toxin highly specific to zebra and quagga mussels. It can be released as dead cells near the mussels, which ingest it, with the toxin destroying their digestive system. In this way it is similar to Bacillus thuringiensis israelensis (Bti), which is valued for its very specific toxicity to certain insect pests. CL145A is specific enough that it has been used to kill zebra mussels smothering native freshwater mussels, leaving the native mussel unharmed! It is sold as a product called Zequanox, which hasn't been a huge hit due to its comparative expense compared to other solutions. It also can reduce dissolved oxygen in the water when applied indiscriminately. Scientists are trying to find similar targeted solutions that will kill invasive golden mussels, currently spreading through aqueducts and reservoirs in California. #clamFacts
