أكد علماء أن أخطبوطاً أزرق بحجم كرة الغولف هو نوع غير معروف سابقاً، وذلك بعد فحص عينة تم جمعها من أعماق المياه قبالة جزر غالاباغوس.

تمت ملاحظة هذا الكائن، الذي أطلق عليه اسم Microeledone galapagensis، لأول مرة في عام 2015 خلال بعثة استكشافية في أعماق البحار على متن السفينة E/V Nautilus بالقرب من جزيرة داروين. واستخدم باحثون من مؤسسة تشارلز داروين ومديرية حديقة غالاباغوس الوطنية مركبة تعمل عن بعد لرصد الكائن على عمق حوالي 5800 قدم. وقد جمع الباحثون عينة واحدة وسجلوا مقاطع فيديو لاثنين آخرين من نفس النوع.

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 أبريل، 2026 من إعداد الذكاء الاصطناعي

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.

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.
