by Giovanna GIRARDI Agence France-Presse VENICE, Italy (AFP) — “The flora and fauna of the lagoon have not changed during lockdown. What has changed is our chance to see them,” says zoologist Andrea Mangoni, plunging his camera into Venice’s normally murky waters to observe life. A crab tries to grab the intruding lens, jellyfish propel themselves along near the surface, schools of fish swim peacefully by, crustaceans cling to the city’s famous jetties, and seaweed of […]
PARIS, France (AFP) — A species of jellyfish hunts its prey by hurling venom grenades to create “stinging water”, researchers said Thursday, solving a long-standing mystery as to how they gather food without tentacles. The Cassiopea xamachana jellyfish, found in shallow waters around Florida, the Caribbean and Micronesia, is a frequent nuisance to snorkelers and surfers who appear to get stung without touching the creatures. It was thought that the stings came from detached tentacles […]
SYDNEY, Australia (AFP) — Australian researchers believe they have found an antidote to a sting from the world’s most venomous creature, the much-feared box jellyfish. Researchers at the University of Sydney had been investigating how the venom is so deadly that one box jellyfish can kill 60 people. The team noticed the venom needs cholesterol to kill human cells and decided to test whether existing drugs could stop it. “Since there are lots of drugs […]
CALIFORNIA, United States (Reuters) — A brainless, spineless, pulsating organism has a key behavior in common with humans: sleep. While sleep has been confirmed in other invertebrates such as worms and fruit flies, the jellyfish is the most evolutionarily ancient animal that has been shown to slumber. Jellyfish have thrived in the seas for at least 600 million years, longer than nearly any other animal. By comparison, dinosaurs appeared roughly 230 million years ago […]

A prominent feature of the exhibit is the Jellyfish Dream Theater, or the Kurage Dream Theater, measuring five meters in diameter, where about 2000 Moon Jellies float. Many […]
JERUSALEM, Israel (AFP) — Swimmers wanting to avoid being stung by jellyfish may want to watch the sky as much as the sea after Israeli researchers found a link between their arrival and the phase of the moon. The Israeli study found the lunar calendar is a key determinant of when jellyfish arrive on the Mediterranean country’s shores. In the middle of the lunar months — the days before and during the full moon — […]
Reuters — Colorful jellyfish were captured on camera at a depth of 3,700 meters (12,139 feet) on April 24 in waters off south-east Asia. Stunning footage showed two luminous creatures swimming in the dark waters around the Marianas Trench Marine National Monument, east of the Philippines. The footage was captured by a remotely operated vehicle “Deep Discoverer” which holds 20 LED lights and nine video cameras. In an operation running from April 20 to […]
