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.
Pregnant male seahorses tend to develop embryos similarly to the way mammals do, new research shows. Pregnant male seahorses tend to develop embryos similarly to the way mammals do, new research shows. In the new study, scientists found a suite of genes that are turned on in the pouches of seahorses to keep the baby healthy and growing. Similar gene activity has been found in the wombs of mammals and even reptiles. As such, the finding could shed light on the evolution of live birth, called viviparity. Seahorse broods
