Is octopus older than dinosaurs?
The answer might surprise you Scientists in Montana recently found a fossil of an early ancestor of modern octopuses. It lived about 330 million years ago — before the age of dinosaurs.
Octopuses and dinosaurs belong to vastly different evolutionary timelines. Octopuses, or cephalopods in general, have a long evolutionary history dating back hundreds of millions of years, while dinosaurs were dominant terrestrial reptiles during the Mesozoic Era, which began around 180 million years ago and ended approximately 66 million years ago.
Cephalopods, including ancestors of the modern octopus, can be traced back to the late Cambrian period, about 500 million years ago. Fossil evidence suggests that ancient cephalopods had simple, shell-like structures and evolved over time into more complex, diverse forms, ultimately leading to the modern octopus we are familiar with today.
On the other hand, dinosaurs first emerged during the Triassic period around 230 million years ago, with a wide range of species evolving and dominating the Earth during the Mesozoic Era. Dinosaurs exhibited incredible diversity, including various sizes, forms, and ecological adaptations.
Are giant octopus poisonous?
Despite its impressive size, the giant Pacific octopus poses little threat to humans; it typically avoids divers. However, a bite from a giant Pacific octopus contains toxic venom. It is known to cause harm to humans but is not fatal if treated in a timely fashion.
Giant octopuses, specifically the giant Pacific octopus (Enteroctopus dofleini), are not typically considered poisonous. Poison refers to a substance that is harmful or toxic when ingested, touched, or injected into a living organism.
