Alessia Zecchini surpassed her previous CMAS Free Immersion world record by 3 meters on April 19th, reaching a depth of 104 meters. Her record dive took her 3min 46sec.

This new FIM record was established during the Camotes Freediving Challenge near Cebu, Philippines, on its second day. This week-long, limited-entry event began on April 17th. In Free Immersion, divers do not use fins and must descend and ascend by pulling themselves along the rope.

The counterfeit valves can be distinguished from the originals by several differences. These include:

Researchers from the American Museum of Natural History have discovered that the porosity in mussel shells along the East Coast of the United States has increased. The cause is believed to be rising ocean temperatures.  

Porosity can affect the structural integrity of mollusk shells, so this means that the shells are weaker and thus more susceptible to damage. 

The findings was published in the journal PLOS ONE. 

The study identified the parasite that devastated 95 percent of long-spined sea urchins in affected areas in the Caribbean Sea two years ago. It burrows into the tissue of the sea urchins and triggers abnormal behaviour. The urchins droop and lose their ability to control their tube feet, which are crucial for movement. They lose their spines, then tissue necrosis sets in, leading to the death of the sea urchins.

Exactly a week ago my phone started pinging late at night. I was getting messages from too many people who I deem a credible source, of the tragic news that Jared Hires had died at Plura Cave.

I got the news confirmed. Cried. Then opened up my laptop and wrote an article announcing Jared Hire's death. At present over 45,000 of you have read it. 

Conventionally, shark behaviour has been perceived as largely instinctive and uniform across individuals. However, a team of researchers, led by Thomas M. Vignaud, have upended this notion, uncovering a spectrum of individual personalities among bull sharks frequenting feeding sites.

William T. White and his team of researchers described the distinct characteristics of the Roughback Bristle Shark through meticulous examination of its size, coloring, body structure, texture, dental arrangement, egg cases, and genetic makeup, and published their their study in the journal "Fishes." Residing at astonishing depths between 2,200 feet and 3,900 feet, the newfound shark species has, thus far, exclusively inhabited the waters off the western coast of New Zealand's North Island.
