Decorator crabs are more complex than we realized
Decorator crabs are known for their ability to attach algae and small animals to their shells to conceal themselves from predators, but the process is more complex than it appears, and it suggests higher intelligence than we once understood these crabs to have. If the shells of these crabs are cleaned, they will immediately set about replacing their camouflage with the same care and precision as they showed in their first concealment.
There are several species of crabs that use plants, animals, and debris from their environment to adorn their shells. Some chew the algae and then carefully hook the pieces onto velcro-like hooks on their shell. They occasionally use anemones or other sedentary animals. They attach the matter to their shells with great precision and care, suggesting that they are purposefully imitating the surfaces around them. When moved from one environment to another, these crabs will quickly replace their adornments with items from the new location, seemingly understanding the need to blend in with specific surroundings. Their disguise is not random or haphazard.
Decorator crabs will make use of toxic plants or animals as further deterrence for potential predators. Described by scientists as "perhaps unrivalled" mastery of concealment, these are highly specialized behaviours. Understanding the purpose of their covering, these crabs remain still during the day and they freeze in place when threatened. Some species use only sponges, others use only noxious alga. One species selects stinging anemone for it's protective covering. The anemone benefits from an increased supply of food that is available as it moves around with the crab. Octopus have shown a tendency to avoid these crabs when they are adorned with anemone.
The intelligence and purpose of the smallest and seemingly less significant animals is becoming more understood. Perhaps, as we gain greater insight we will also gain greater appreciation and desire to protect them. The balance of nature is a delicate one and humans frequently disrupt this balance in their ignorance of what goes on around them.

Midnight snorkelers capture incredible salamander migration
Every spring, yellow-spotted salamanders migrate to vernal ponds to breed. The result is a frenzy of activity that lasts only 2-3 nights each year. It is a spectacle to behold. The salamanders make their long journey from the surrounding forest under the cover of darkness, usually after a rainfall. The males arrive at the pond first, depositing spermatophores on the leaves and branches in shallow water. The females come soon after, gathering up the spermatophores to fertilize the eggs that they are waiting to deposit.
Soon after the eggs are fertilized, the female will attach herself to a submerged plant stem or twig and she will release the eggs. The eggs are protected by a sticky, gelatinous mass that deters predators as the eggs develop for approximately 30 days. The eggs hatch into tadpoles, similar to frogs and toads. They spend their first few months in the water, breathing through gills.
Salamanders are amphibians. Once they leave the water, they spend most of their lives underground, occasionally coming out of their burrows to feed and also for breeding season in March to May each year. They are rarely seen, although they are plentiful in the forests that they inhabit.
Salamanders excrete a toxic, milky fluid when they are threatened. Salamanders are a major food source for birds, raccoons, foxes and other animals.
Salamanders feed on earthworms, spiders, slugs, snails, and other insects. They have the amazing ability to grow a new tail and new limbs if one is severed.
A salamander has the unique ability to lay two different types of egg masses. One type has a water-soluble, protein-based gel. The other type has a hydrophobic protein-based gel. This is believed to prevent predation by wood frogs. These eggs are combined with an algae that produces oxygen and removes carbon dioxide and nitrogen waste from developing embryos.
The complex relationships between organisms are only beginning to be understood. The health of our forests and our ecosystems depends on the survival of all species, no matter how small.

Drone captures total eclipse over the shore from bird's eye view (Sped up 7.5x)
The eclipse of 2024 created a path of darkness across North America that created lineups and traffic jams, but also awe and wonder. In the space of several minutes, broad daylight turned to near darkness as the rays of the sun were blocked out by the moon passing between the sun and the earth. A drone was sent up to a height of 124m to capture the event. The clouds prevented a view of the sun or the moon, but the darkness sweeping over the shore was dramatic and unsettling. As the light dimmed, the video is sped up to 7.5x. Part of the darkest period is edited out for brevity.
The daylight reappeared as quickly as it left, leaving everyone in awe.
These events are spectacular from the ground, but even more so when filmed from a bird's eye view

Beautiful flamingos squabble in the sunshine
Flamingos are a vibrant and beautiful bird, magnificent in both size and vivid colour. They are a joy to behold and a peaceful sight when they are resting at the edge of a pond or a marsh. But Flamingoes can also be loud when they are disturbed, as we see here. The honking wakes up the sleepy flamingoes. What happens next is a comical brawl involving honking, squabbling and feigned pecking at each other. Aside from a bit of harmless beak rubbing, there is nothing substantial about this episode, but the sound of it suggests that an enthusiastic fight has broken out.
Great debates have raged regarding the flamingo's habit of standing on one leg. One theory is that this is to assist with conservation of body heat. When flamingos feed and wade in colder water, they lose heat through their legs. Adopting a sleeping position with one leg out of the water lessens the heat loss while they are sleeping or resting. Sleeping in a mud flat or pond allows them to hear the telltale splashing if a threat approaches while their guard is down. But flamingos in warmer climates and those that feed in warm water adopt the same sleeping position so this theory is contradicted in some cases.
Another theory is that the muscular effort to stand on one leg is much less so the position is adopted to reduce energy expenditure required for balance. Studies show that resting flamingos sway less than those that rest on two legs.
Flamingos are gorgeous birds and so brightly coloured that we cannot help but admire them. When gathered in a group, they are simply breath taking in their beauty.
The beautiful sunshine adds another layer to the scene, casting a golden glow on the pink feathers of the flamingos and enhancing the overall aesthetic appeal. It's almost like nature's own masterpiece, with the elegant birds engaging in their natural behaviors under the warmth of the sun.
Observing flamingos in such moments can be truly captivating, offering a glimpse into the intricate dynamics of their social structure and the beauty of the natural world.

Captivating Video Captures Bluebird's Delicate Landing at Bird Box Nest
In the midst of our bustling lives, there are moments of serenity that remind us of the delicate beauty that surrounds us. One such moment recently captured the hearts of nature enthusiasts worldwide: a mesmerizing video showcasing a bluebird's graceful landing at a bird box nest.
The video, shot by avid birdwatcher and amateur videographer portrays a scene straight out of a tranquil woodland dream. Set against the backdrop of lush greenery, the bird box nest stands as a sanctuary, a safe haven for the bluebird family.
As the footage begins, anticipation hangs in the air like a soft breeze. The camera focuses intently on the bird box, its wooden frame weathered by seasons past. Suddenly, a flash of azure appears—a bluebird, its wings outstretched like sails catching the wind.
With precision and finesse, the bluebird navigates the airspace, each movement a testament to its aerial prowess. It approaches at the perfect angle before gracefully alighting upon the edge of the bird box entrance.
The moment of landing is nothing short of magical. The bird's slender legs extend, delicately grasping the wooden perch, while its azure feathers shimmer in the gentle sunlight. For a brief instant, time stands still, and all that exists is the quiet elegance of this avian visitor.
As the bluebird settles into the nest, a sense of tranquility washes over the viewer. It is a reminder of the intricate dance of life that unfolds in the natural world—a dance in which every creature plays a vital role.
Moments later, the bird leaves the nest, off in search of another meal for its babies inside the box.
Witnessing moments like these reminds us of the profound beauty of nature. It's a privilege to capture such intimate glimpses into the lives of these remarkable creatures.
Indeed, the video of the bluebird's gentle landing serves as a poignant reminder of the interconnectedness of all living things. In a world often dominated by chaos and noise, it is moments like these that beckon us to pause, to breathe, and to marvel at the simple wonders that surround us.

The beauty and mystery of Roatan revealed
Roatan is an island in the Republic of Honduras. It is home to more than 41,000 people. It is also one of the world's most beautiful tourist destinations. A group of Canadians made their way to Roatan to experience the magic and the mystery of this unique place. They were not disappointed.
The warmth of the people is one of the first things that grabs you in this little piece of paradise. The food, the smells, and the abundance of culinary choices make exploring this island a pleasure that doesn't stop.
This video provides a close up look at the mystery and wonder of Roatan, filmed on land, underwater, and from the air. The beauty is unrivaled and the magic is unforgettable. Roatan should be on everybody's bucket list.
The animals in Roatan are fascinating. An indigo hamlet darts about, showing off the brilliant blue colour that gives it the name, divers exploring with Native Sons Dive Centre carry their tanks across the beach, hop on a boat and depart on an adventure they will not forget. Two giant porcupine fish frolic over the coral, curious about the divers. An orange spotted file fish changes colour in seconds to blend in with the reef, a spotted eel hunts for food, a school of squid glide past, and a grouper lurks in the soft corals. A great barracuda shows its menacing teeth, a blue spotted file fish regards the divers as it eats algae, and dog tooth snappers follow the divers, hoping for a handout.
A grouper hides in a barrel sponge, getting a teeth cleaning from his little wrasse friend. An upside down jellyfish pulsates on the sand, creating a flow of water to filter nutrients. A basket star expands in the darkness to reach out for its meals, and a moray eel patrols the sea bottom, hoping to ambush an octopus or a fish. a string jellyfish, almost invisible drifts on the current, and a massive channel clinging crab walks along, eating algae. A giant midnight parrot fish turns around in its crevice. A moray eel investigates the camera. A queen angel fish shows off her stunning colours, a school of surgeon fish provide a beautiful display, and a peacock flounder blends in on the sand with impressive camouflage. Creole wrasses dance over the coral head. Scuba divers explore a mysterious swim through, a box fish nibbles, and hungry sharks compete for fish scraps in a controlled feed. Guests visit a sanctuary and get a close look at parrots, sloths, and monkeys. A fire dancer gives a mesmerizing performance on the beach (Moni Noo). Amid shouts of taco taco taco, one of the locals performs as he cooks his wares. A boat takes us on a tour of the mangroves, home to thousands of species that come here to hide until they are big enough to survive in the ocean.
A visit to Roatan provides memories that will last a lifetime.

Grouper in Roatan gets a teeth cleaning by his little friend
Groupers are intelligent fish, and capable predators. They ambush their prey or actively hunt fish, octopus, and crustaceans. They create a powerful suction as they open their mouths and inhale their prey. Small fish are wise to avoid the powerful jaws of the grouper.
But the ocean is a complex world with many unusual relationships that exist between the inhabitants here. The grouper has found a resting spot in a large barrel sponge. The sponges are animals, although they are rooted in place, unable to move. They draw sea water in and pass it out, filtering nutrients that they consume as food. The gentle water flow may be enjoyable for the grouper as it also enjoys the concealment from predators and their intended prey. Barrel sponges are the longest living animals on the planet, occasionally reaching 2500 years.
This grouper is involved in a mutually beneficial arrangement with the small wrasse that darts in and out of its mouth. The wrasse is known as a cleaner fish and they hide among the corals and sponges until they are called into action. A larger fish such as this grouper signals the wrasse by tilting upwards and opening its mouth wide. The wrasse trusts the grouper in an age old contract that provides the wrasse with food as it cleans the teeth of the grouper. This benefits the grouper by preventing rotting material from remaining in the mouth, causing infections and sores. The grouper gets free dental care and the wrasse gets a meal. The grouper will not break the trust of his little friend.

Massive hippos bask in the afternoon sun beside the river
Hippos are massive animals that live in Africa. They are the third largest land mammals on earth. Only elephants and white rhinos are larger. They can reach an incredible 4.9m (16 feet) in length and a mass of 1500kg (3,300lb). Due to their aggression and their size, adult hippos are rarely preyed upon. Young hippos are occasionally taken by lions or crocodiles. Surprisingly, the hippo's closest relatives are whales and dolphins. Aquatic mammals like whales evolved from land animals that were very similar to the hippo. Originally, it was believed that hippos were closely related to pigs due to molar structure and other similarities, but DNA and fossil records have c hanged this line of thinking in the past century.
Hippos are most active at night, roaming the shallows along riverbeds in Africa. They are herbivores, eating aquatic vegetation, and occasionally farm crops, which contributes to conflict with humans. Known to be aggressive, even when not provoked, hippos will occasionally charge humans or boats.
The hippo produces a red oil, as can be seen on these sunbathing adults, which acts as a sunblock, protecting them from UV rays.
Fascinating creatures, they are best regarded from a distance as they can be ferocious and deadly.
