33 facts about Platypus

11.The body temperature of a platypus is about 32 °C (90 °F) which is rather unheard of in other mammals, reaching 37 °C (99 °F)
This is an adaptive trait, resulting from the need to adapt to the conditions of the environment in which they live.
12.A young platypus has molars that fall out as it begins to explore the environment outside the nest.
In their place appear heavily keratinised pads with which it crushes food. It has cheek-pouches, in which prey is carried to the surface, where it is consumed.
13.The structure of the platypus' eye indicates that over the years of evolution they have been adapted to an aquatic and nocturnal lifestyle.
The structure of the platypus eye resembles that of sea lions and otters.
14.The cervical spine of the platypus consists, as in most mammals, of seven cervical vertebrae.
It has cervical ribs and additional bones in the shoulder girdle, such as the interclavicular bone, not found in other mammals, and the coracoid bone (which is well developed in birds, reptiles, and amphibians).
15.The platypus is well adapted to diving.
These adaptations include:
  • bradycardia (a condition in which the heart rate is less than 60 beats per minute)
  • Bohr effect (reducing the affinity of hemoglobin for oxygen under conditions of reduced pH).
16.The platypus breathes using its lungs.
The lungs are not symmetrical. On the right side they consist of two lobes and on the left side they consist of one lobe. Below the lungs is the diaphragm.
17.A platypus doesn't really have a stomach.
Instead it has separate pouch where food collects. Digestion is carried out by the pancreas and the glands of the digestive tract wall.
18.Platypuses feed primarily on invertebrates that live on the bottom of bodies of water.
In rivers they find shrimp, crayfish, annelids, and insect larvae. They hunt by catching floating specimens or by digging in the bottom of the water body.
19.Platypuses spend about 12 hours a day foraging for food.
While diving they can stay underwater for about 40 seconds. Between one dive and another platypuses rest above the water surface for about 20 seconds.
20.They are active during dusk and night.
During the day, they can only be found when the sky is clouded over.
