The leakiest capillaries, which allow large substances such as cells to cross the capillary walls are called sinusoidal capillaries.
Sinusoidal capillaries are a unique kind of capillaries that are wide in diameter. The diameter of a sinusoidal capillary is 30 to 40 nm.
Sinusoidal capillaries can be found in the liver, spleen, and bone marrow. In the spleen, sinusoidal capillaries help in the filtration of blood. They remove broken red blood cells, antigens and other pathogens remains in the blood.
Sinusoidal capillaries are known as leakiest capillaries because all other capillaries have a narrow diameter and do not allow the passing of large substances. Sinusoidal capillaries are the only ones with a large diameter that allows the passing of larger substances.

Answer:
They have a vacuole inside, that stored the nitrate needed to oxidize sulfide and obtain energy.
Explanation:
<em>Thiomargarita namibiensis</em> is the largest prokaryotic bacterium yet known, it has a spherical shape and reaches up to a size of 0.75 mm wide, which makes it visible to the human eye. It was discovered on the shores of Namibia and It is known as "Sulfur Pearl of Namibia," due to the sulfur granules they store inside and the brightness they produce. The problem with its large dimensions is the larger the surface of the bacteria, the lower the level of nutrient absorption. therefore this bacterium had to develop other mechanisms of nutrient and energy uptake
The survival mechanism of this bacterium is quite particular, first of all, it is an anaerobic bacterium, so it is found in sulfide-rich sediments. Its main feature is a liquid container inside called vacuole, which occupies 98% of its volume. In this vacuole, the nitrate that the bacteria use to oxidize sulfide is stored and thus obtain energy. <em>T. namibiensis</em> is unable to move, so they have to wait until the sea currents transport nitrate-rich seawater to store it in their vacuoles, so they can survive for up to 3 months without any other external substrate.
