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.
Male platypuses have sharp spurs on their back legs shaped like a canine tooth. These hollow spurs measure 0.59 to 0.71 inches long and connect to crural glands in the animal’s upper thighs.
The platypus (Ornithorhynchus anatinus), sometimes referred to as the duck-billed platypus, is a semiaquatic, egg-laying mammal endemic to eastern Australia, including Tasmania. The platypus is the sole living representative or monotypic taxon of its family Ornithorhynchidae and genus Ornithorhynchus , though a number of related species appear ...
Mebs writes that venomous animals produce venom in a group of cells or gland, and have a tool, the venom apparatus, which delivers the venom by injection during a bite or sting. The venom apparatus in this definition encompasses both the gland and the injection device, which must be directly connected.
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 ...
In addition, incidents of opiliones biting people are rare, and no reported bites by these species have had any lasting effects. The term "daddy-long-legs" also can refer to the similar-looking cellar spider. This species (a true spider) can bite humans, but its venom is not known to have any effects beyond mild discomfort at the site of the bite.
Depending on the type of tick and the individual person's immune system, they may have a large obvious rash — or nothing at all. People that do notice tick bites often see a bump that is: Small ...
Feeding bites may also contain digestive enzymes, as in spiders; spider bites have primarily evolved to paralyse and then digest prey. A sting comes from the abdomen; in most insects (which are all largely hymenopterans), the stinger is a modified ovipositor, [16] which protrudes from the abdomen. The sting consists of an insertion wound, and ...
