Why it is important to regulate shark fisheries in Indonesia

Shark fisheries in Indonesia are an important economic resource in several areas. Hence, stronger regulations are needed to prevent declines in shark population.

Shark Week looms, but don’t panic

Media coverage of sharks often exaggerates risks to people, but more than 500 shark species have never been known to attack humans, and there’s lots to learn about them.

From sharks in seagrass to manatees in mangroves, we’ve found large marine species in some surprising places

Far more megafauna species use coastal wetlands than we thought. And it affects the way we need to address the extinction crisis.

Sequencing the white shark genome is cool, but for bigger insights we need libraries of genetic data

Why do scientists spend so much time and money mapping the DNA of species like white sharks? Single studies may offer insights, but the real payoff comes in comparing many species to each other.

Some sharks have declined by 92% in the past half-century off Queensland’s coast
