1. Cephalopod Color Conversations

The next time you walk into a mollusk bar, you might just catch an octopus channeling its inner Beyoncé: "Who run the world? Squids!": Cephalopods, including squids, octopuses, and cuttlefishes, don't just change their skin color and pattern for camouflage but also to communicate with their fellow invertebrates. Male Caribbean reef squids flirt in red and throw out white signals to keep rivals at bay, while the Humboldt Squid's flashing colors are believed to be their unique silent disco-esque mode of conversation.

They say laughter is the best medicine, but it seems mollusks might have a more solid prescription: they're armed with teeth made of the strongest natural material known to humankind! No joke here: mollusks possess teeth made from a mixture of goethite nanofibers and a protein matrix, which tests from the University of Portsmouth have shown to withstand pressures that are capable of turning carbon into diamond – putting their dental fortitude well ahead of Kevlar, on par with top-tier carbon fibers, and undeniably stronger than spider silk. Now that's something to chew on!

Giant clams: the DJs of the sea, laying down colorful vibes and wicked algae mixes on their reef decks.

Their reproduction involves external fertilization, and their protein-rich soft body has led to overexploitation. Luckily, conservation efforts and aquaculture are striving to save these disco mollusks from extinction.
