Blue-ringed octopi are deadly. What you need to know about blue-ringed octopus venom. These squids are seldom observed alive, and typically they can be studied at length only when a corpse is discovered.
Sperm whales have been discovered with battle scars apparently inflicted by the suckers of giant squids, and with squids' beaks in their stomachs. This indicates that although giant squids might be formidable fighters, they are not the biggest, strongest or most dangerous creatures in the ocean.

Cephalopod Poisons Fortunately for land-dwellers, octopus and squid defense mechanisms aren't a serious threat to humans. Giant Squid One of the most persistent myths regarding octopus and squids is that of the giant squid -- a massive creature who sinks ships and feasts on humans.
What is the Arm of the Squid? The team focused on three species found in northeastern and southern Australian seas: the blue-ringed octopus, the sand octopus, and the reef cuttlefish. In addition to finding venom proteins, the team discovered that the venom genes from all three species seem to come from a common ancestor.
Octopus venom also appears to contain similar proteins to those in other poisonous creatures such as snakes. By studying proteins from various cephalopods, the researchers hope to understand why so many different toxic creatures seem to share a similar basic venom chemistry. Knowing more about the properties that make specific chemical brews work as toxins could aid in human drug design, the study authors say.
That's because many animal venoms have already shown promise for treating ailments such as pain, allergies, and cancer. All rights reserved. According to a new study, all octopuses, cuttlefish, and some squid are venomous.
The work might also have implications for medical research, according to the study authors. Common Ancestor Fry and colleagues collected tissue samples from hundreds of cephalopod species during several expeditions in the waters around the Great Barrier Reef, Hong Kong, and Antarctica.
