Marine Snails Have Unique Swimming Patterns, New Study

In the world's oceans, billions of tiny marine snails commute daily between surface waters, where they feed at night, to depths of several hundred meters during the day to rest.

Marine snails play an important role in geochemical cycles and climate: 12-13% of the global carbonate flux occurs when the calcium carbonate shells of dead snails sink to the depths, where they dissolve and contribute to atmospheric carbon and ocean acidification. But because they are difficult to study and can't be kept in the laboratory, the behavior of these animals is poorly known, especially for the subtropical and tropical regions where their diversity is greatest.

According to a study published Monday in the Frontiers in Marine Science journal, a US team led by researchers at the University of South Florida tried to address this lack of information. They filmed the movements of tropical marine snails and analyzed these both from a fluid physics and ecological perspective. They showed that each species has a distinct style of swimming and sinking depending on the shape of their shell (coiled, elongated, or round), and body size.

Between 2017 and 2019, the researchers caught multiple individuals of nine species of marine snails and transported them to the laboratory, where they recorded their behavior in a salt-water aquarium with a high-speed technique that tracks movement in 3-D with a pair of cameras. For each species, they calculated the absolute and normalized speed (relative to body length) during active swimming and passive sinking, the frequency of wing movement, the angle of descent during sinking, the tortuosity of the path of ascent during swimming, and the shells number.

The researchers found that each species has a distinct swimming pattern. Tiny snails with coiled shells swim more slowly whereas larger snails with bottle-shaped or wing-shaped shells swim faster because their larger sizes allow them to overcome the effects of water viscosity.

In a report published by the Frontiers in Marine Science journal, author Dr. David Murphy, assistant professor at the Department of Mechanical Engineering of the University of South Florida, said: "Understanding the swimming ability of these animals is helping us better understand their ecological importance and distribution in the ocean. Further, we hope to learn from the swimming style of these organisms to design a new generation of bio-inspired underwater vehicles."

iRead Marathon Records over 6.5 Million Pages Read

The fifth edition of the iRead Marathon achieved a remarkable milestone, surpassing 6.5 million pages read over three consecutive days, in a cultural setting that reaffirmed reading as a collective practice with impact beyond the moment.

Hosted at the Library of the King Abdulaziz Center for World Culture (Ithra) and held in parallel with 52 libraries across 13 Arab countries, including digital libraries participating for the first time, the marathon reflected the transformation of libraries into open, inclusive spaces that transcend physical boundaries and accommodate diverse readers and formats.

Participants agreed that the number of pages read was not merely a numerical milestone, but a reflection of growing engagement and a deepening belief in reading as a daily, shared activity accessible to all, free from elitism or narrow specialization.

Pages were read in multiple languages and formats, united by a common conviction that reading remains a powerful way to build genuine connections and foster knowledge-based bonds across geographically distant yet intellectually aligned communities, SPA reported.

The marathon also underscored its humanitarian and environmental dimension, as every 100 pages read is linked to the planting of one tree, translating this edition’s outcome into a pledge of more than 65,000 trees. This simple equation connects knowledge with sustainability, turning reading into a tangible, real-world contribution.

The involvement of digital libraries marked a notable development, expanding access, strengthening engagement, and reinforcing the library’s ability to adapt to technological change without compromising its cultural role. Integrating print and digital reading added a contemporary dimension to the marathon while preserving its core spirit of gathering around the book.

With the conclusion of the iRead Marathon, the experience proved to be more than a temporary event, becoming a cultural moment that raised fundamental questions about reading’s role in shaping awareness and the capacity of cultural initiatives to create lasting impact. Three days confirmed that reading, when practiced collectively, can serve as a meeting point and the start of a longer cultural journey.

The Imam Turki bin Abdullah Royal Nature Reserve Development Authority launched the fifth annual beekeeping season for 2026 as part of its programs to empower the local community and regulate beekeeping activities within the reserve.

The launch aligns with the authority's objectives of biodiversity conservation, the promotion of sustainable environmental practices, and the generation of economic returns for beekeepers, SPA reported.

The authority explained that this year’s beekeeping season comprises three main periods associated with spring flowers, acacia, and Sidr, with the start date of each period serving as the official deadline for submitting participation applications.

The authority encouraged all interested beekeepers to review the season details and attend the scheduled virtual meetings to ensure organized participation in accordance with the approved regulations and the specified dates for each season.

The Hail Region Municipality has secured first place in the Arab Green City award for 2024-2025 at the 15th session of the Arab Towns Organization.

This recognition honors the municipality’s commitment to environmental sustainability, the expansion of green spaces, and the implementation of urban practices that elevate the quality of life, SPA reported.

The award follows a series of strategic environmental initiatives, including large-scale afforestation, the modernization of public parks, and the adoption of eco-friendly solutions to enhance the urban landscape and resource efficiency.

By aligning its projects with the sustainability goals of Saudi Vision 2030, the municipality continues to foster a healthy and safe environment for residents and visitors.

This achievement establishes Hail as a leading Arab model for sustainable urban development.
