Cientistas confirmaram que um polvo azul do tamanho de uma bola de golfe é uma espécie desconhecida até então, após examinarem um espécime coletado em águas profundas próximas às Ilhas Galápagos.

O animal, chamado Microeledone galapagensis, foi observado pela primeira vez em 2015 durante uma expedição em águas profundas a bordo do E/V Nautilus, perto da Ilha Darwin. Pesquisadores da Fundação Charles Darwin e da Direção do Parque Nacional de Galápagos usaram um veículo operado remotamente para avistar a criatura a uma profundidade de cerca de 1.768 metros. Eles coletaram um espécime e registraram em vídeo outros dois do mesmo tipo.

A mother-and-daughter duo of citizen scientists has uncovered the largest known coral colony on Australia's Great Barrier Reef, measuring 111 meters across and covering nearly 4,000 square meters. The J-shaped formation of Pavona clavus was found during a dive as part of the Great Reef Census initiative. Advanced 3D modeling confirmed its size, highlighting the role of community involvement in marine conservation.

Giant squid traces reveal hidden marine world off australia

Scientists have uncovered evidence of giant squid and hundreds of other species in deep submarine canyons off Western Australia. The findings come from an expedition that used environmental DNA analysis to explore depths exceeding 4 kilometers.

Fossil jaws reveal giant ancient octopuses as apex predators

25 de abril de 2026 Reportado por IA

Researchers have uncovered evidence that octopuses from the Late Cretaceous period, around 100 million years ago, grew to lengths of nearly 20 meters and hunted as top predators. The findings, based on well-preserved fossil jaws from Japan and Vancouver Island, challenge previous views of early octopus evolution. Professor Yasuhiro Iba of Hokkaido University led the study, published in Science on April 23.

Scientists warn US actions accelerate Pacific coral reef collapse

A team of international researchers has accused the US government of hastening the collapse of coral reefs around Guam through military expansions and proposed rollbacks to the Endangered Species Act. In a letter published in Science this month, they highlight how national security priorities are overriding conservation efforts. Without changes, these reefs face functional extinction similar to those in Florida.

Researchers launch EuroWorm project to document European marine worms

An international team of scientists has started the EuroWorm project to create an open-access genomic database of European marine annelids, aiming to discover species before they vanish. Led by the Leibniz Institute for Biodiversity Change Analysis, the initiative focuses on these vital segmented worms that support ocean ecosystems. The effort combines museum collections with modern genomics to accelerate global biodiversity research.
