Types of Catheters. There are three main urologic catheter types to choose from. Intermittent catheters, hydrophilic catheters, and closed system catheters. Intermittent Straight catheters. Straight catheters are a straight tube of flexible plastic or rubber. One end has a rounded tip, and the other end typically has a funnel end.
Female sloths give birth to one baby a year after a gestation period of six months. The baby sticks with the mother for about six months, grasping its momâs belly as she moves through the trees. This is an important bonding period that helps the offspring learn and develop.
For Rhesus monkeys it is 164 days and baboons 187 days. For small animals such as rabbits the period is about 33 days and for mice about 20 days. So it takes a longer time for a big animal such an elephant to grow a baby than for a smaller animal such as a mouse. The baby of the bigger animal is of course bigger but there are the bigger resources of the big animal to promote that growth so it is not obvious that bigger animals would have longer gestation periods.
