Why are there no insects in the sea?

Before I start this post, I would like to make it clear that I am not an entomologist, so I apologize if I say anything very wrong; I hope not. Although I am sure many of you, indeed connoisseurs of the subject, are already thinking, “there are insects in the sea”. Certainly, several species of Halobates liveContinue reading “Why are there no insects in the sea?”

PLASTIC: You are plankton and to plankton you shall return

Today, I’m going to talk about public enemy number 1, plastic; and more specifically, I’ll tell you about their interaction with marine plankton. Plastic, from the Greek plastikos: which can be shaped, is a word that includes a multitude of products of different origin and chemical composition. Some are more or less natural, but most areContinue reading “PLASTIC: You are plankton and to plankton you shall return”

Sapphirina, an astonishing show of light and color

Today I present to you a copepod that has been called the most beautiful animal in the world, the Sapphirina. Sapphirins are parasites of gelatinous plankton, especially doliolids, into which they enter and devour. While this fact is terrifying and would make them worthy of a post within this blog, this copepod also has otherContinue reading “Sapphirina, an astonishing show of light and color”

Plankton, mussels with french fries, and diarrhea

The Belgians have the culinary tradition of eating mussels with French fries; it is all a matter of taste. In Catalonia, on the other hand, we serve them alone, in sauce, or in paellas or other equally delicious dishes. Mussels, apart from being a gastronomic delight, available to everyone, are incredibly efficient filtering machines. InContinue reading “Plankton, mussels with french fries, and diarrhea”

Are there carnivorous plants in the sea?

Whether because of Audrey from Frank Oz’s musical Little Shop of Horrors, or because of The day of the Triffids of John Wyndham’s, or even because of the little venus fly trap plants sold in the flower shops, everybody knows what carnivorous or mixotrophic plants are. You may even have tried to grow one at home, probablyContinue reading “Are there carnivorous plants in the sea?”

Copepods: Good things come in small packages

Imagine a group of organisms more abundant than insects; so abundant that if we place them in a row touching each other by the antennas one could reach the sun and return. That they were the main source of food for fish, to the point that without them there would probably be none left inContinue reading “Copepods: Good things come in small packages”

The rhythms of plankton

The dichotomy between day and night drives most rhythms in nature. The sun activates photosynthesis and with it, thousands of biochemical, physiological, and ethological processes. Humans sleep mostly at night, but many beasts thrive in the dark. During the night we see the moon, which also has its rhythms around 28-29 days. The duration betweenContinue reading “The rhythms of plankton”
