Have you ever wondered why Mako sharks swim so fast through the water? Well, researchers have found out how they are able to handle the resistance of a medium such as salt water. <a href= "https://www.newscientist.com/article/2195435-worlds-fastest-shark-gets-a-burst-of-speed-from-shape-shifting-skin/"> It all comes down to their denticles.</a> Mako sharks have flexible denticles that move to lower the resistance of water in places that will offer the most resistance (the gills) where flow separation exists. Flow separation is where water passes over a structure quickly and then slow down to form tiny eddies. The flexibility in the denticles offers less resistance and takes away the flow separation allowing the shark to continue to gain speed through the water. Researchers have already used this technology in making swimsuits and now they are looking towards the skies to make helicopters more efficient. Find out how by listening to the episode.

SUFB 732: Why Are Mako Sharks So Fast

Dive into the Depths: Join Andrew Lewin on 'How to Protect the Ocean' – Your Gateway to Exclusive Ocean Insights! Explore the latest, uncharted realms of ocean science and conservation that you won't find anywhere else. Andrew takes you on an inspiring journey to uncover the hidden gems of oceanic discovery and initiatives. Tune in to discover how you can transform your life for a better ocean, one episode at a time.

The How To Protect The Ocean is your resource to keep you informed on the latest ocean news; teach you how to speak up for the ocean; and, how you can take action to live for a better ocean. 

There is so much information on the ocean and the issues that are affecting it that it can be difficult to find optimism in the future of the ocean. Climate change, overfishing, plastic pollution, water pollution, and coastal development have altered the ocean in ways that have negatively changed the way we use it. 

The repercussions of climate change, including the ominous specter of rising sea levels, the relentless march of warming ocean temperatures, and the ominous shadow of ocean acidification, have not only altered the very fabric of our coastlines but have also conjured fiercer storms and summoned floods with growing frequency. The fossil fuel industry may whisper in your ear that the situation is insurmountable, an inescapable fate. However, this podcast is here to unveil a different narrative, one that empowers you to take action. It illuminates the path to change by casting your vote for leaders committed to implementing climate-rescuing policies and by offering invaluable insights into how each of us can shrink our individual carbon footprint.

The grim reality of overfishing casts a long shadow, fueled by governmental shortcomings in the stewardship of both commercial and recreational fisheries. Within the delicate balance of our oceans, every fish population possesses a threshold - a point at which the relentless harvest of fishermen begins to erode their numbers. The management of these aquatic resources is a formidable task, as the elusive currents of the sea often defy easy tracking. Furthermore, the menace of illegal, unregulated, and unreported (IUU) fishing looms large in many nations, adding to the crisis.

Yet, a glimmer of hope shines through the depths. A beacon for responsible consumption emerges in the form of seafood programs, guiding conscientious individuals toward choices that safeguard our oceans. By heeding these programs, you not only savor the delights of sustainable seafood but also become an informed guardian of marine ecosystems.

The relentless scourge of plastic pollution has unleashed an epidemic of death upon the denizens of our oceans. It's a ruthless killer, claiming the lives of hundreds of thousands of marine mammals, majestic sharks, grandiose fish, gentle sea turtles, and the graceful sea birds that soar above. The malevolence of this crisis knows no bounds, with microplastics infiltrating even the remotest depths of the ocean and etching their presence along every coastline.

To mount a defense against this ecological cataclysm, the clarion call for action echoes on the international and national stages. It beckons governments far and wide to adopt resolute policies, wielding the power to outlaw the menace of single-use plastics and demanding the meticulous detoxification of our supply chains. In this grand battle to safeguard our seas, the fight against plastic pollution knows no borders.

The ominous specter of water pollution looms large, a consequence of our thoughtless disposal into the arteries of our planet – our streams, rivers, lakes, and oceans. This callous act reverberates, sending shockwaves through the intricate ecosystems of our coastal havens, where the likes of coral reefs, resilient mangroves, and swaying seagrasses thrive. But alas, this intrusion is not benign; it bears the capacity to corrode and dismantle these vital sanctuaries, the very lifeblood of countless fish and the steadfast guardians of our vulnerable shorelines.

Yet, amidst the unsettling tide of pollution, there emerges a ray of hope. Through individual resolve and visionary government policies harnessed with cutting-edge technology, we can stem this toxic deluge. Water treatment systems stand as stalwart guardians, armed with the ability to sift out the insidious nutrients that fuel destructive algal blooms. The power to heal our waters and preserve the sanctity of our coastal treasures lies within our grasp.

Coastal development, driven by human desires to construct homes or fortify the shoreline against erosion, represents a significant intervention in the natural order. Yet, these changes, while initially confined to the coastal zone, often send ripple effects that extend far beyond their original boundaries, casting a shadow of unintended consequences.

The repercussions of altering coastlines resonate through interconnected ecosystems, occasionally triggering a cascade of events that can inflict profound harm on distant areas. In doing so, this well-intentioned transformation can unwittingly imperil the lives and livelihoods of communities residing in the wake of its impact. It is a stark reminder that our actions along the coast carry a profound responsibility, not just to the immediate environment but to the greater web of life and society that depends upon it.
