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.
Species. There are between 30 and 40 species of seahorses worldwide, and possibly as many sub-species. It is often difficult for scientists to identify seahorses because individuals of the same species can vary greatly in appearance.he female transfers her eggs to the male which he self fertilises in his pouch. The number of eggs can vary from 50-150 for smaller species to 1500 for larger species. They receive everything they need in the pouch from oxygen to food. Gestation time varies from 14 days to 4 weeks.
