Eels

Saltwater Eels

General description Eels are one of the most fascinating and one of the most demanding species of saltwater fish kept by aquarists. They are characterized by their long, snake like bodies and scale-less, mucus covered bodies. Unlike most other species of fish, eels do not have separated dorsal, anal and caudal fins. Instead their fins merge together to create a continuous fin ridge along their bodies. Most species of eel are nocturnal and highly predatory. And due to their aggressive temperament should only be kept by experienced aquarists. Eels are one of the most fascinating and one of the most demanding species of saltwater fish kept by aquarists. Origins Most species of saltwater eel originate from the Western Atlantic Ocean Color Saltwater eels come in an array of colors ranging from green, yellow, brown, grey and black.

Bichirs

Bichirs General description Bichirs are a species of primitive freshwater fish. They are characterized by their long, eel-like bodies and unique dorsal finlets. These spiny finlets vary in number from 7- 18 and have double edged tips. The rest of the bichir fins are spineless and are made of soft rays. Their body is covered in thick, bone-like scales which along with its fleshy pectoral fins give it its prehistoric appearance. Most bichir are large in size and can reach up to 38 inches in length. There are a lot of unique traits this unusual fish breed boasts. Bichirs are capable of breathing surface air through a specialized swim bladder and can use their powerful pectoral fins to crawl over short distances over land. Owing to this, they will need a large aquarium with a lid, as they’re prone to slinking out of the tank. These freshwater fishes are imposing nocturnal carnivores, and as such, they will need to be housed properly. Choose their tankmates carefully and make sure that they’re only housed with compatible roommates- in other words, those fishes that won’t become their food or eat all of the food. Bichirs are certainly an impressive breed, with a distinct ancient appearance that appeals to many aquaristics enthusiasts. Their prehistoric looks also earned some of the varieties appropriate common names, such as the dinosaur eel, dinosaur Bichir, swamp dragon, or dragon fish. If you are looking for an unusual-looking addition to your freshwater tank and think Bichirs are a perfect choice, read on to see if this breed is compatible with your set up and its inhabitants. Bichirs are a species of primitive freshwater fish. They are characterized by their long, eel-like bodies and unique dorsal finlets. Origins All species of Bichir are native to tropical Africa and the Nile River system, extending their habitat to India as well. They live in muddy waters and hide in vegetation to hunt their prey. Experts claim that Polypteridae, which is the scientific name for this fish family, first appeared in the last period of the Mesozoic era. This means that these ray-finned fishes don’t only look archaic, but they actually are ancient- their family has been around for about 60 million years. In addition to their thriving populations in the wild, Bichirs are also bred in captivity and make a popular aquarium fish. Color If you want a flashy fish whose vibrant colors will brighten your tank’s interior, this freshwater fish breed is not for you. Bichirs are often dull colored in shades of brown, grey and black. There are some minor exceptions to this rule, though, with varieties such as Ornate Bichir. The black and yellow intricate patterning might not be as exotic as the colorful scales of Discus or Flowerhorn, but it is far more impressive than beige and grey tones of other Bichirs.

Why Won't My Bearded Dragon Eat?

It can be concerning when your bearded dragon suddenly stops eating - especially if you’re not sure what’s causing the change. Bearded dragons are generally good eaters, so a lack of appetite is usually a sign that something’s off. The good news is that most feeding issues have identifiable causes, and once you figure out what’s wrong, you can usually correct it. Here’s what to consider if your bearded dragon won’t eat.Improper Tank ConditionsOne of the most common reasons for appetite loss is incorrect temperatures or lighting inside the enclosure. Bearded dragons rely on external heat to digest their food. If the basking area is too cool, their metabolism slows down, and they may stop eating altogether.Make sure your setup includes:A basking area between 95–110°FA cool side around 75–85°FProper UVB lighting, replaced every 6 to 12 months depending on the typeUVB light is essential for synthesizing vitamin D3, which helps them absorb calcium. Without it, bearded dragons can develop serious health issues, including loss of appetite.

New Research Reveals Dog Diversity Dates Back to the Ice Age

From the adorable little Pug snuggling on the couch to the towering Irish Wolfhound patrolling the yard, there is no questioning the incredible physical diversity of today’s domestic dog. It has been a commonly held belief among the dog-loving community that this variety was a recent development, resulting from the creation of modern dog breeds. Throughout the years, breeders and dog enthusiasts have focused on intensive, aesthetic-focused selective breeding to meet the breed requirements established by the formation of kennel clubs and the development of structured dog breeds as we know them today. So, are these differences the result of a few hundred years of human intervention aimed at creating dogs with specific looks and features? New research suggests there may be more to it than we realize! The research, published in the journal Science, suggests that the fundamental differences seen in dogs, specifically in their skulls, date back to the tail end of the last Ice Age, at least 11,000 years ago. Scientists examined a massive collection of 643 skulls, including those of modern dogs, ancient dogs, modern wolves, and ancient wolves, covering roughly 50,000 years of canine history. They found that the emergence of recognizable domestic dog features and significant variation between dogs appeared soon after they branched out from their wolf ancestors. “During domestication, dog skulls became proportionally shorter and wider compared with those of wolves,” explained bioarchaeologist and study co-lead author Carly Ameen of the University of Exeter in England. The dog was the very first animal domesticated by people. While ancient dogs didn’t possess the extreme facial features of a modern Bulldog, Ameen notes that dogs from the Mesolithic and Neolithic periods already showed about half the skull variation we see in all the different breeds today. But back then, they weren’t picking dogs based on how cute they looked; they were choosing them strictly for what they could do, their function and purpose. The relationship between humans and dogs was purely a working partnership for millennia. Dogs fulfilled crucial roles, including serving as hunting partners, herders, guards, and sled pullers. Early human societies selected dogs based on what they could best do, and with those practical needs came related physical features. For example, a shorter, stronger snout performed better for gripping, while a longer muzzle was better for tracking.    It was only in recent centuries that the way dogs are viewed in society shifted. As dogs became more integrated into our lives beyond their functional roles, preferences driven by status and appearance began to take over. As breed standards were formalized, these differences intensified and grew into the dog breeds we recognize today.  What does all this mean for us as modern-day dog parents? The research is a powerful reminder that the dog sleeping at our feet (or in our bed) is the result of a vast history based on function and practicality. Their unique and adorable appearance is not just a product of 200 years of focused breeding; it’s a testament to an 11,000-year-old story of evolution, where their physical form adapted to help humans survive and thrive. They were man's best friend back then and continue to be today. Join the PetGuide community. Get the latest pet news and product recommendations by subscribing to our newsletter  here.

What Should You Pack for a Perfect Dog Beach Trip?

Summer is coming to an end, but that doesn’t mean the magic of summer is behind us yet. The days are still long and warm! It’s the perfect time to soak up those last beautiful golden rays and make some unforgettable memories with your pup.While many people think of summer vacations as a thing of the past when August rolls around, my pups and I know better. This is a prime opportunity to plan one last epic beach getaway.But a great beach trip is going to require a little more preparation than just grabbing a towel and a toy before running out the door. To ensure your dog’s day playing in the water is both safe and fun, you need to create a more comprehensive dog beach checklist. This guide is your roadmap to a worry-free day at the beach, highlighting all the essentials you need so you can both enjoy every moment of your time together.Before You Go A perfect day at the beach with your dog starts long before you ever leave the driveway. It all comes down to a little bit of planning and research. Finding a Dog-Friendly Beach First and foremost, you’ll need to choose the right dog beach. Not all beaches are created equal when it comes to our furry friends. Before you load up the car, do a quick search for local dog-friendly beaches, reading up on their specific rules and reviews from other dog parents. Does your dog need to be on a leash? Are they allowed in only certain areas or during specific hours? Knowing these details in advance will save you from a frustrating trip and potential fines. It’s also a good idea to check the weather forecast and the tide schedule when planning your trip. A beach at low tide offers more space to run and play, while high tide might mean less shoreline. Knowing the weather will help you avoid getting trapped out in rough weather like heavy rain or a thunderstorm. Is Your Dog Ready for the Water? While some dogs leap into the waves without a second thought, others are more hesitant. It’s crucial to remember that not all dogs are natural swimmers, and that’s perfectly okay. My boy Lucifer was afraid of the waves at first and now loves swimming. However, my girl Willow has no interest in anything more than walking through the very edge of the water. If this is your dog’s first time at the beach, take it slow. Let them get their paws wet on their own terms. Encourage them with praise and treats to step into the shallow water. Don’t force it or you could create a negative association, turning them off the idea of swimming moving forward. If they’re happy just wading along the shoreline, that’s a success! A positive first experience will go far in helping you build their confidence and ensuring they will enjoy future trips. Beach Bag Essentials for Your Dog-Friendly Trip Your beach bag should be more than just a place to stash your sunscreen and a roll of poop bags; it’s a safety kit for your best friend. Every item you pack can make a world of difference. Water Safety It’s tempting to think your dog can handle the water on their own, but even the strongest swimmers can get tired or caught in a current, depending on the conditions where you’re swimming. This is where a life jacket becomes your best friend. A properly fitted dog life jacket provides buoyancy and can be a lifesaver, especially for breeds that aren’t natural swimmers, puppies, or older dogs. Most life jackets also have a handle on the back, which is incredibly useful for guiding your dog in the water or lifting them back into a paddleboard or boat if you head out paddling. We recently switched to the Ruffwear Confluence Life Jacket for Lucifer and love that it offers protection in an emergency while still allowing him to run and play. Playtime Preparedness Playing fetch on the beach is a classic, but what you throw matters. A simple stick can seem like a great toy, but it can lead to some serious risks. Sticks can splinter in your dog’s mouth, causing cuts and internal injuries. Pieces can also be swallowed, leading to intestinal blockages that require emergency surgery. Instead, pack safe, durable, and brightly colored floating toys. Our go-to is the Chuckit! Air Fetch Ball. These are easy to spot in the water and are designed for safe play. While playing fetch in the water, be mindful of how much water your dog is ingesting. Overconsumption can lead to water intoxication, a rare but life-threatening condition where a dog’s sodium levels drop dangerously low. If you notice your dog becoming lethargic, bloated, or uncoordinated, take a break from play and give them a chance to rest. Paw Protection The sand might feel cool and soft to you, but it can get scorching hot under the sun. Before letting your dog walk on it, check the sand’s temperature with the back of your hand. If it’s too hot for you to hold your hand on for a few seconds, it’s too hot for your dog’s sensitive paw pads. In these cases, consider bringing booties, like the Canada Pooch Dog Boots for Hot Pavement, to protect their paws from burns. Dog Sunscreen Just like us, dogs can get sunburns, especially on areas with less fur, such as their noses and ears. If your dog has a light-colored, short, or thin coat, they are even more susceptible. Applying a dog-specific sunscreen to these sensitive areas can help prevent painful burns and reduce the risk of skin cancer. Alternatively, you can use a UV protection shirt like the Spark Paws Sunblock Dog T-Shirt with SPF 30 sun protection. Never use human sunscreen, as many of the ingredients are toxic to dogs if ingested. Emergency Supplies Even with careful planning, minor accidents can happen. Having a small, portable first aid kit can make all the difference. You can purchase a pre-made dog-friendly first aid kit or create your own with all the necessary emergency supplies. Your kit should include: Vet wrap for holding bandages in place Antiseptic wipes to clean minor cuts Saline solution to flush out sand or debris from their eyes Tweezers to remove small splinters or ticks Paw ointment to soothe irritated paw pads Finally, before you leave the house, double-check that your dog’s ID tags are securely attached and that the information is up to date. It’s a simple step that can increase the chances of getting your pup home safely if they happen to wander off.
