Hammerhead Shark

The hammerhead shark is one of the most dangerous sharks on Earth, and it gets even worse when you consider that there are over 30 species of hammerheads. These sharks live in tropical waters around the world, including in the Atlantic Ocean, Indian Ocean, Pacific Ocean, and Caribbean Sea. They grow up to about 3 meters long and weigh up to 300 kilograms. Their body shape makes them look like a hammer, hence the name “hammerhead”.

These sharks eat fish, squid, octopus, crustaceans, turtles, seabirds, and occasionally small mammals. However, unlike many other sharks, hammerheads do not attack humans unless provoked. In fact, some people say that they are friendly sharks because they are calm and curious.

DISTRIBUTION of Hammerhead Shark

The world’s largest cruise ship, Harmony of the Seas, has arrived in Sydney Harbour. The 466,800 tone vessel left Southampton on Monday morning and is expected to dock at Circular Quay around midday. It is carrying 2,500 passengers and crew and will spend three weeks docked in Australia.

Harmony of the Seas is part of Royal Caribbean International’s Oasis Class ships – a class of vessels designed to offer guests a wide range of activities and entertainment options. The Harmony of the Seas offers a variety of dining venues including the award winning steakhouse, Guy Fieri’s Poolside Kitchen; the casual eatery Guy’s Pig & Anchor Bar; the buffet-style restaurant, Windjammer Cafe; and the specialty restaurants, Sabor Latino and Tarpon Bend. There are multiple bars, lounges, and nightclubs onboard, along with shops and boutiques.

Harmony’s sister ship, Allure of the Seas, debuted in May 2016. The 716,000 tonne vessel features 3,400 guest staterooms, nine swimming pools, six whirlpool tubs, a wave pool, fitness centre, rock climbing wall, mini golf course, basketball court, ice skating rink, theatre, casino, and cinema.

Royal Caribbean Cruises Ltd. operates 14 ships under the brands Celebrity Cruises, Azamara Club Cruises, Princess Cruises, Regal Princess Cruises, Radiance of the Seas, Enchantment of the Seas, Brilliance of the Seas, Navigator of the Seas, Discovery of the Seas, Mariner of the Seas, Voyager of the Seas, Liberty of the Seas, Freedom of the Seas, and Symphony of the Seas.

A new study from the University of California San Diego School of Medicine shows that eating a diet rich in fruits and vegetables may help prevent or delay Alzheimer’s disease. Researchers found that older adults who ate more than five servings per day had a lower risk of developing Alzheimer’s disease compared to those who consumed fewer than two servings daily.

ECOSYSTEM/HABITAT of Hammerhead Shark

Coastal to Open Ocean (Pelagic)

The coastal to open ocean transition is one of the most important shifts in marine ecosystem structure and function occurring worldwide today. This shift represents a fundamental change in the physical environment, the distribution of species and the nature of interactions among organisms.

This transition occurs because coastal habitats are being destroyed and replaced by open water habitats. In addition, the productivity of coastal ecosystems declines due to increasing nutrient loading and sedimentation. As a consequence of these changes, many coastal fish populations decline while pelagic fish stocks increase.

In contrast to coastal systems, open ocean ecosystems support large numbers of species, including commercially important species such as tuna and swordfish. However, there are few data on how pelagic ecosystems are changing over time.

To address this gap, we compiled published information on pelagic ecosystems around the world and analyzed it to identify trends in biodiversity, trophic dynamics, habitat use and environmental conditions. We found that pelagic ecosystems are becoming increasingly productive, supporting larger biomass, greater diversity and greater abundance of commercial fisheries. These changes are associated with increased primary production and enhanced vertical mixing in the upper mixed layer.

While pelagic ecosystems are experiencing positive changes, there are still substantial challenges facing these systems. For example, climate change is likely to affect the availability of prey resources, particularly zooplankton. Furthermore, the high cost of monitoring pelagic ecosystems makes it difficult to understand how these ecosystems respond to environmental perturbations.

These findings provide insight into the global patterns of change in pelagic ecosystems and highlight areas where research needs to focus in order to better understand the future of pelagic ecosystems.

FEEDING HABITS of Hammerhead Shark

The world we live in today is one where people are constantly bombarded with information about everything under the sun. This has led to a phenomenon known as “information overload,” where we feel like we’re drowning in data. To make matters worse, our brains aren’t built to process it all. So how do we filter out what we don’t want to hear? We turn to technology.

A study published in the journal PLOS One found that people are much better at ignoring unwanted information when presented with a visual cue. In fact, researchers discovered that simply seeing a picture of a penguin next to a headline about climate change makes us less likely to read the latter.

This finding holds true even for text headlines. A study conducted by researchers at University College London found that people are far more likely to ignore a headline containing a picture of a penguins than one without. Researchers believe that the reason why pictures work so well is because they allow you to quickly scan something visually and determine whether or not it’s relevant to you.

So while some might say that having a picture of a penguine next to a headline about global warming gives us too much choice, it actually works to our advantage. While we could choose to read the article about climate change or skip over it altogether, we’ll opt for the penguin instead.

Fun Facts About Great Hammerhead Sharks

The great hammerhead shark is one of the most common sharks in tropical waters around the world. In fact, it is the second most commonly caught shark worldwide. This large fish can grow up to 18 feet (5.5 m) in length and weigh over 500 pounds (230 kg), making it the biggest of all nine hammerhead shark species. Its name comes from the unique shape of its head, which resembles a hammer.

Hammerheads are found in warm coastal waters throughout the tropics and subtropics. They prefer shallow reefs and seagrass beds where there is plenty of food to eat. These sharks feed primarily on bony fishes such as groupers and snappers, though occasionally they prey on smaller reef animals like crabs, octopuses, sea turtles and even small sharks.
