Jeanne Villepreux-Power (1794 – 1871), was a pioneering #French marine biologist, described by English biologist Richard Owen as the "Mother of Aquariophily."

In 1832 she was the first person to invent and create aquaria for experimenting with aquatic organisms.

Personal note: She created the first offshore research stations — a system of immense cages she anchored off the coast of #Sicily, complete with observation windows through which she could study #argonauts * undisturbed. 🐙

(* an octopus known as paper #nautilus for the thin, intricately corrugated shell of its females and the sail-like membranes protruding from it like a pair of bunny ears)

Every day, she prepared food for them, rowed her boat to the cages in her long skirts (👀 !!), and knelt at the platform, observing for hours on end.

As one can imagine, that got old fast (!!) so, in order to transfer her observations and experiments ashore, she pioneered the #aquarium.

Massive kraken-like octopuses may have ruled the seas 100 million years ago.
New analyses of fossilized jaws reveal that massive, kraken-like octopuses once hunted alongside other marine predators. They boasted eight arms and long bodies that extended more than 60 feet (18 metres), rivaling other carnivorous marine reptiles

Nice to visit the #Octopus #Kraken tentacle, just across the road from the #OggCamp #OggCamp2026 venue 
'Kraken' #octopus that lived at the time of the dinosaurs was a 62-foot-long apex predator of the ocean. "These were not just Cretaceous octopuses, but giant, intelligent, and highly formidable marine predators."

A close inspection of 27 fossil jaws from finned octopuses challenge the longstanding belief that the apex oceanic predators of the Cretaceous were all vertebrates.

just when you thought it was safe to go back into the Cretaceous again… #GiantOctopus #octopus #octopodes #cephalapoda

A massive kraken-like octopus may have prowled the seas during the age of dinosaurs.

From @AssociatedPress: "Researchers studied the jaws of 15 ancient octopus fossils that were previously found in Japan and Canada’s Vancouver Island."

Kraken-like octopuses may have been top predators during the Cretaceous

The top predator prowling the seas during the age of the dinosaurs 100 million years ago may have been an octopus. New analyses of fossilized jaws reveal that massive, kraken-like octopuses once hunted alongside other marine predators. Their bodies extended more than 60 feet, rivaling other carnivorous marine reptiles. It's difficult for scientists studying ancient octopuses to figure out exactly how big they got because their soft bodies don’t preserve well. In a new study, researchers used fossil jaws to estimate the creatures' size and what they might have eaten. The findings were published Thursday in the journal Science.
