The snake is in fact responding to the movement of the flute, not the sound it makes, as snakes lack external ears (though they do have internal ears). [ 131 ] The Wildlife Protection Act of 1972 in India technically prohibits snake charming on the grounds of reducing animal cruelty.
As a result, it has recently been reclassified as a dangerous species. Rear-fanged snakes need to bite and hold on, or repeatedly bite, to have any effect on humans. A chewing action facilitates envenomation, as the venom ducts open to fangs that are externally grooved (not hollow) and are posterior in the oral cavity.
Some tortoises show negligible senescence. Negligible senescence is a term coined by biogerontologist Caleb Finch to denote organisms that do not exhibit evidence of biological aging (), such as measurable reductions in their reproductive capability, measurable functional decline, or rising death rates with age.

Unlike humans and other mammals, snakes do not possess an outer ear, a middle ear, and a tympanum but have an inner ear structure with cochleas directly connected to their jawbone. [95] They are able to feel the vibrations generated from the sound waves in their jaw as they move on the ground.
By 2009, the population recovered to 11,980 snakes, safely exceeding the population minimum goal of 5,555 adult snakes required by the 2003 recovery plan. Monitoring was to occur for 5 years following this delisting. The Lake Erie watersnake is just the 23rd species or subspecies to be removed from the list due to recovery. [33]

The reticulated python is among the few snakes that prey on humans, and is the only species of snake where video and photographic proof exists of them having consumed humans. In 2015, the species was added to the Lacey Act of 1900, prohibiting import and interstate transport due to its "injurious" history with humans. [44]
The eastern garter snake is broadly considered non-venomous. Garter snakes do have a Duvernoy's gland, and the secretion from the gland may be chewed into prey during bites. The secretion is noted to cause hemorrhaging in mice and has produced non-allergic symptoms in at least one bite on a human. [3] [4] [5]
