Admittedly, the idea of protecting seagrass is not as “glamorous” as protecting the rainforest, but this marine vegetation is essential to both marine life and humans. A new study by scientists from Cardiff University, Swansea University and Stockholm University, and published in the Fish and Fisheries journal, highlights the global importance of seagrass to fisheries.

“Wherever you find seagrass and people, there is most certainly fishing,” said Dr Leanne Cullen-Unsworth, from Cardiff University’s Sustainable Places Research Institute.

We’ve all seen those huge schools of fish that move as one and coordinate their movements so perfectly. New research has come up with a way to map the chain of direct interaction in such schools of fish, discovering that the fish pay attention to one or two of their neighbours at a time when the school moves as a group.

The initial purpose of the bill, called The Access for Sportfishing Act of 2016, was to prevent national parks from trying to protect fish in waters within state jurisdiction, and in June, Senator Bill Nelson, from Florida, added the ban on shark feeding diving in federal waters. The bill specifies that it is all right to feed sharks for the purpose of killing them, but not if you want to watch the shark. Thus it is the motive for the act of shark feeding, rather than the act itself, that is at issue.

The Twelfth Session of the Conference of the Parties to the Convention of the Conservation of Migratory Species of Wild Animals (CMS CoP12) was held in Manila, Philippines, between October 23 and 28. It resulted in added international protection for sharks and rays and several other migratory species, and the decisions were endorsed by the 90 governments attending.

Working on Palmyra atoll, around 1,000 miles south of Hawaii, a team of researchers from the University of California Santa Barbara became aware of the fish's farming habit when they noticed many bite marks in specific areas of algae growing on dead coral.

They followed these patches through time and found parrotfish were feeding heavily in each patch for a short period of time. Then, the fish would allow that exact location to recover before returning to harvest the algae again.

Seashells come in various shapes and sizes. And it appears that the seashells from the tropics tend to be larger than those found in the temperate regions.

Far from being just a coincidence, it seems that there is a rational explanation for it. Simply put, this is because the sea snails in the tropics have to devote relatively less energy to shell growth, compared to those in the cold-water regions.

Last summer, Lamar Hires, Dive Rite's CEO, joined a group of like-minded divers from Rango Extendido to explore Silfra. This is Iceland's infamous fissure, where you can dive in the crack between two continental plates and simultaneously touch North American and Eurasian.

A study has revealed that shark dive tourism in Australia contributes at least AUD$25.5 million annually to the country’s economy. These findings highlight the importance of proper management of shark species to support a sustainable dive tourism industry.

Focusing on four main shark viewing industries in Australia, the study was a collaboration between Australian Institute of Marine Science (AIMS), Flinders University, University of Western Australia, and Southern Cross University. It surveyed 711 tourist divers from May 2013 to June 2014.
