From @joannechocolat

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.

The Chambered Nautilus is one of the oldest surviving marine species on Earth, with a lineage that dates back more than 500 million years. Long before dinosaurs existed, these creatures were already drifting through ancient oceans, and remarkably, they have changed very little since then.
Unlike octopuses or squids, the nautilus retains an external shell, divided into chambers that help control buoyancy.

Meet the 19 metre octopus that may have prowled ancient seas

Giant octopuses may have ruled the oceans 100 million years ago, according to fossil evidence.

One blue whale song unlocks oceans of data

Trying to find a whale song in the ocean is like trying to find a needle in a haystack. But now, UNSW Sydney researchers say they've trained a model, with just a single case study, to find blue whale songs in recordings that span across decades and entire ocean basins.

Drones aid dugong conservation as threats mount across their range

Drone technology is providing important new insights into the lives of dugongs, while also revealing the vital role they play in managing seagrass meadows, one of the ocean’s most important carbon sinks. Often referred to as sea cows, dugongs (Dugong dugon) are marine herbivores that can grow up to 3 meters (10 feet) long and […]

Oyster growers enduring 'death by a thousand cuts' after being closed again
By Tom Mann and Isabella Kelly

Oyster growing areas on the Yorke Peninsula are ordered to close due to the detection of a toxic phytoplankton for the second time this year.
