I showed my latest wheatpaste to my friend Alex and he said

"Wait. Are there other sea nuts?"

Which broke my brain for a minute.

There are: Acorn Barnacles Acorn Worms Peanut Worms

Almond❌ Cashew❌ Pistachio❌ Brazil Nut❌

I feel like there SHOULD be a sea pecan, but no.

status: Species of Special Concern

These neat creatures do not sting and naturally occur along the east coast North and South America. Unfortunately these voracious eaters have become an invasive species of European waters.

Some comb jellies survive the winter by eating their young

You wouldn’t want this creature as a parent. An invasive species of jellyfishlike animal in the Baltic Sea may survive harsh winters by consuming large numbers of its larvae, new research suggests.

Mnemiopsis leidyi—commonly known as the sea walnut (above), because of its shape—is native to the western North Atlantic Ocean. But it has proliferated in European waters in recent decades, likely after hitching rides in the ballast waters of cargo ships. In the western parts of the Baltic Sea, the species’ end-of-the-summer population booms ravage the base of the marine food web, including fish eggs, fish larvae, and small crustaceans. But the creatures need lots of food to bulk up for winter—and the largest source of sustenance at that point is their own offspring.

What a Nut!— Invasive Species Week

This ctenophore (a stingless jellyfish-like animal) called a sea walnut is native to the east coast of North and South America. In 1982, it was discovered in the Black Sea, where it was transported by ballast water. It subsequently spread to the Caspian Sea. In both places, it multiplied and formed immense populations. The sea walnuts contributed to the collapse of local fisheries because they feed on zooplankton that the commercial fish also consume. Mnemiopsis leidy has also been discovered in the Mediterranean, Baltic, and North Seas.
