There are a few possibilities: Other Turtles This site about pet turtles mentions the possibility that turtles fighting over a mate (or actually mating) may end up on their backs. When breeding season comes around, adult male turtles might start fighting over the females. A stronger male might flip a weaker one over. Male turtles might also harass ...

Theoretically, it might be possible to survive on fish, rainwater and desalinated seawater. In one 1930 experiment, two men survived for a year eating exclusively meat without experiencing any health issues. This indirectly suggests that meat (and therefore possibly also fish) contain all the essential nutrients, but this was a small and relatively short ...

The best answer I’ve come up with so far is to combine neoprene paddling gloves such as those sold by NRS with an additional pair of waterproof or semi-waterproof mitten shells designed to be worn over gloves / mittens. This has kept my fingers completely comfortable in air temperatures well below freezing while paddling through rivers or bays where ice is ...

... can someone gather/hunt/farm all of the nutrients required to be healthy whilst never having to land again? Nutrients yes, healthy not likely. A 1000 days is a grueling journey. Reid Stowe, whom used to have a website called (Beyond) 1000 Days at Sea: The Mars Ocean Odyssey, lived at sea (without contact with land) for 1,152 days (equals 3 Years, 1 ...

I haven't been paddling much for several years, but I used to go all winter with simple fleece gloves inside waterproof dishwashing rubber gloves. I tried a half dozen other alternatives, including wetsuit gloves, other waterproof gloves, pogies, etc. Fleece insulation and waterproof outside worked best, and was also very inexpensive.

Well, firstly, there's generally no need, given that any reasonable navigator carries a compass, thereby allowing the direction to be determined. With two or more known lights in sight, a simple resection gives the vessel's position. However, some lights are set up to give rapid indication of whether the vessel is on the right heading in one of two ways: ...

Summary: Develop muscle memory for the basic move through instruction and repetition, develop robustness against external water conditions, and address the internal panic response. Develop muscle memory: get some instruction and then practice the basic mechanics of a roll until you can do it thoughtlessly. The investment in the instruction is well ...

In addition to the reasons given in @John Hughes answer, Predators may be another cause. This SeaWorld Parks & Entertainment page on the longevity and causes of death of sea turtles lists tiger sharks and killer whales (orcas) as the main predators of adult turtles. This YouTube video (also featured, with additional notes, in this LiveScience.com ...

In short, just the name. Fjord is of Norse origin, loch of Gaelic. They are the same feature, formed when glaciers debouch into the sea. In both countries, you'll find varying scales, from a few hundred metres in width to several kilometres.

I'm pretty sure it's some kind of a suet cake/fat ball, i.e. bird's food, see the first image on the Wikipedia article: https://en.m.wikipedia.org/wiki/Suet_cake (Luc Viatour / https://Lucnix.be)

Sometimes known as paddle mitts, pogies are your friends here, you can choose to wear gloves in them as well or not, depending on how cold it's got, but most importantly they allow you full contact with the paddle and hence you don't get the extra fatigue caused by a reduced level of paddle control. Pogies range from a simple nylon shell that keeps the wind ...

It looks like radar reflectors will not hurt but they aren't great either. The bigger and higher they are the better, which is easier to do on a sailboat than a sea kayak. According to one study, a homemade reflector worn on the paddler's hat provided the best signal reflections. The distance they can be seen regardless of a radar reflector is limited, ...

The most important factor is to have some slack in your roll. If you're only just coming up in flat water you're not going to be coming up as soon as there's an additional factor against you. Make sure that as you practice your roll you're not at the end of your movement as you come up. The places to find that slack are to: improve your hip flick ...

Allow me to turn your question on its head a bit. Making yourself more visible to large vessels is a good idea, not being where they need you to be visible is a great idea. Stay away from channels, shipping lanes, and docking areas. You are small and in a craft that can turn and stop in mere inches- a laden freighter on the other hand, might measure those ...

There is a of type navigational aid that partially provides some bearing information, and that is a range marker. Such markers occur in pairs, positioned close enough together to both be seen at the same time, yet far enough apart to be visually distinct from each other. Further, the two markers are placed at different heights, so that one always appears ...

As already pointed out in a comment, your question is based on a misconception. In poor visibility, such as at night, navigators can tell which direction the lighthouse is from the ship, but it doesn't help them know which direction the ship is relative to the lighthouse. If you know one of these bearings, you automatically know the other: it's just the ...

As the other answer suggests, this is a sea urchin. Specifically, it appears to be a commonly caught species off Maine called Strongylocentrus droebachienisis, which is commonly called the green sea urchin (or Atlantic green urchin). Source: brownetrading.com The OP's image shows the urchin's mouthparts (the so-called "teeth" of Aristotle's lantern), ...

When building their nest, octopus usually place some kind of shiny object at the entrance to find the place back if they leave. They probably don't for their eggs, as they don't leave them, but you never know. In any case, the best way to ensure you won't disturb them is to keep your distance from reefs, so that you don't scare them. Another thing to be ...

Assuming that you are looking for the ideal conditions for a surfable wave to form, I will leave some of the conditions that I take in consideration Wind Direction. The wind direction is essential and ideally look for offshore (wind blowing from the shore). The speed of the wind is related with the size of the wave. The longer the wind blows the larger ...

Your question implies that having a radar reflecting hat is somehow going to prevent you getting hit by a large ship that is using radar. This is at best wishful thinking. In most cases human powered boats have the right of way, except in narrow channels. A vessel of less than 20 meters in length or a sailing vessel shall not impede the passage of a ...

It's a very good question. I found an article that has some suggestions: Finally, it is important to consider your visibility on radar and at night. The best way to ensure that you are seen on radar is to use retro-reflective tape on your kayak, paddle blades, and PFD. I recommend putting 6inch long strips of Solas ® retro-reflective tape on both sides ...

Here is a suggestion, though somewhat wacky is perhaps more realistic than the "hat" idea. The page Sailing Safety Secrets - Are You 'Radar Visible' to Ships at Sea? says that the reflector should be as high as possible. For a boat with no masts, that can only be done by towing a kite, or a helium balloon. What should the reflector be? A tinfoil hat or ...

It depends on your lure/bait, if you have. Fishing is also a lot about luck. Right fish, right lure/bait, you could get one.

It is very hard to tell from the poor photo, but I suspect that it is a member of the Tunicates, a class of marine animals that includes things like sea-squirts. More specifically I would guess that it is a member of the Pyrosomes, which are more commonly found in warm waters, such as are found off Goa. Pyrosomes are actually colonial organisms composed of ...

It seems like you buy bodysurf/bodyboard fins as @Brent point it out. Lifeguard (like me) enjoy it too, as it allow you to do medium length sprint (50 to 100 meters, like 100 to 300 feet) at record speed, while being easy to carry in your hand all day long. These are great for strong acceleration, sharp turn, quick dive under waves and take waves to surf it....
