The southern blue ringed octopus (Hapalochlaena maculosa) is an agile carnivorous predator. It will lure victim prey by wiggling the tip of an arm like a worm; or gliding nearby and pouncing and dragging prey towards its powerful beak-like jaws. Once bitten, the octopus injects it’s prey with poisonous saliva to kill it. This octopus produces venom that contains tetrodotoxin, 5-hydroxytryptamine, hyaluronidase, tyramine, histamine, tryptamine, octopamine,taurine, acetylcholine, and dopamine! #blueringoctopus. #bluering #octopus #cephalopod #predator #oceanimaging

The Extinct Thylacine or Tasmanian Tiger

The Thylacine was the largest known carnivorous marsupial of modern times.  It is commonly known as the Tasmanian tiger (because of its striped lower back) or the Tasmanian wolf.  Native to continental Australia, Tasmania and New Guinea, it is believed to have become extinct in the 20th century.  It was the last extant member of its family, Thylacinidae;  specimens of other members of the family have been found in the fossil record dating back to the late Oligocene.

The Thylacine had become extremely rare or extinct on the Australian mainland before British settlement of the continent, but it survived on the island of Tasmania along with several other endemic species, including the Tasmanian Devil.  Intensive hunting encouraged by bounties is generally blamed for its extinction, but other contributing factors may have been disease, the introduction of dogs, and human encroachment into its habitat.  Despite its official classification as extinct, sightings are still reported, though none has been conclusively proven.
