An aldosterone test measures the level of aldosterone (a hormone made by the adrenal glands), in the blood. Aldosterone helps regulate sodium and potassium levels in the body. This helps control blood pressure and the balance of fluids and electrolytes in the blood. The kidney hormone renin normally stimulates the adrenal glands to release aldosterone.
A seahorse* can have from 100-1500 babies. Averagly 100-200 for most species, but may be as low as 5 for the smaller species, or as high as 1,500. Seahorses can have up to 1500 fry at one time, depending on the species. They are tiny and difficult to raise in captivity.
There are 200 or more species in the family, 35 of which are seahorses. Seahorses have some remarkable adaptations, including hard bony armor on the body, a prehensile tail that can be used for gripping, binocular vision, excellent camouflage and an unusual form of reproduction.eproduction: Most species of seahorses mate for life. After dawn each day, the female swims to the male, and they both change color and perform a special dance, which lasts for about 10 minutes. They separate for the rest of the day, and repeat their dance the next morning.
