The platypus is one of the few living mammals to produce venom. The venom is made in venom glands that are connected to hollow spurs on their hind legs; it is primarily made during the mating season. [1] While the venom's effects are described as extremely painful, it is not lethal to humans.
When a platypus feels threatened, it will stab its spurs into its attacker and inject this toxic venom. Fortunately for humans, platypus venom isn’t fatal, but it does cause extreme pain. In ...
A platypus bill may look like a duck’s bill, but it has a secret ability. The bill contains receptor cells that detect the electric signals made by all living things. As it swims in the water ...
However, monotremes like the platypus, along with reptiles and birds, undergo meroblastic cleavage, in which the ovum does not split completely. The cells at the edge of the yolk remain continuous with the egg's cytoplasm, allowing the yolk and embryo to exchange waste and nutrients with the egg through the cytoplasm.
The hairs in this flank area are highly specialised; at the tips they are like ordinary hair, but are otherwise spongy, fibrous, and absorbent. The rat is known to deliberately chew the roots and bark of the poison-arrow tree (Acokanthera schimperi), so-called because human hunters extract a toxin, ouabain, to coat arrows that can kill an ...
Researchers saw the white platypus 10 times between February 2021 and July 2023, the study said. Several short videos show the rare animal floating along the surface of the river before quickly ...
As such, by some definitions, they do not have stomachs as an organ, [38] although the term is widely used in studies of monotreme anatomy. [39] [40] Monotremes synthesize L-ascorbic acid only in the kidneys. [41] Both the platypus and echidna species have spurs on their hind limbs.
Among the monotremes, the platypus (Ornithorhynchus anatinus) has the most acute electric sense. [37] [38] The platypus localises its prey using almost 40,000 electroreceptors arranged in front-to-back stripes along the bill. [34] The arrangement is highly directional, being most sensitive off to the sides and below.
