Platypus foraging behavior and eating habits!

The platypus’ eating habits and behaviors are very unique and cool! Platypus eat freshwater shrimp, larvae, worms, water snails, aquatic insects, and sometimes the eggs of frogs and fish, and they dedicate around 12 hours each day simply to finding food! The way the platypus locates its food is by using its bill. The platypus bill is really fascinating! It has hundreds of receptors, which are able to detect touch and electric currents created by the movements of their prey, which is known as electroreception.  This is really important for the platypus because when they are underwater hunting for their prey they actually have their eyes, ears, and nostrils closed so they are completely dependent on the capabilities of their bill.  The way the platypus uses its prey detecting bill capabilities is by moving its head back and forth to locate any prey in the surrounding area. Once the platypus has located and captured its prey, it then stores the food in the pouches of its cheeks until the pouches become entirely full. At this point, the platypus swims back up to the surface (using its webbed feet to propel itself) where it separates the food from any sand that it picked up in its mouth while capturing its prey. Another cool thing about the platypus is that adults actually do not have teeth! Platypus young have three molars but lose them when they enter adulthood. In order to eat, they actually grind their food between the pads they have in place of teeth. These pads in the platypus’ mouth are not actually in the bill, however, the platypus mouth is located underneath its bill. Lastly, the platypus uses its tail for fat storage. In fact, the platypus stores up to 50% of its body fat in its cute tail!

  1. This is really cool! So does the platypus use its tail for other things because it has so much fat in it? Does it actually use its tail to swim or is it just a body part there to store fat? It would also be really cool if the platypus was able to defend itself using it's fat filled tail. That would be awesome.

  2. Wow! the platypus is a very interesting animal. After reading the evolutionary post and this one it seems like they have had quite an unique evolutionary process and have adapted behaviors and characteristics from a diverse range of reptiles, birds and mammals. I wonder what the use of the molars are in the young..

  3. The Platypus is awesome. I am interested in how its stores so much of its body fat in its tail. I wonder how that behavior evolved over time and what the function of it is. Thanks for all the fun videos!
