Octopuses are mollusks.
Definitely the blue ringed octopus! The blue ringed octopus is VERY venomous! This type of octopus can shoot it's venom through the water!
Tetrodoxtin is the type of toxin contained in blue-ringed octopus saliva, the same type of poison that puffer fish have. A milligram or less, about a pin-head amount, is all that is needed to kill an adult human.
It depends on the size and type of the octopus and shark. A giant octopus can kill and eat a leopard shark, but a common octopus will be a prey of a tiger shark. Blue ringed octopus have deadly venom enough to kill a full-grown whale shark.
I think it depends on the type of octopus. I think the most common type of octopus is called the Common Octopus (octopus vulgaris). Hence the name! One of the most venemous types of octopus is the Blue Ringed octopus. If you are looking for a better answer search for 'types of octopuses' and maybe it will tell you which ones are more common.
The Pacific Ocean is home to several species of octopus, including the common octopus (Octopus vulgaris), the giant Pacific octopus (Enteroctopus dofleini), and the blue-ringed octopus (Hapalochlaena spp.). The giant Pacific octopus is particularly notable for its size and intelligence, while the blue-ringed octopus is known for its potent venom. Other species, such as the California two-spot octopus (Octopus bimaculatus), also inhabit this ocean, showcasing the diversity of octopus life in Pacific waters.
The color of an octopus depends on its mood. Also the color changes. Only some octopuses have the same color which are very rare like the souther blue-ringed octupus.
blue ring
I believe it was a Blue Ring, native to Australia.
It may be hard to say, but it depends on the type of the jellyfish. A box jellyfish or a portuguese man of war has slightly more powerful toxic than blue ringed octopuses. Portuguese man of wars poison is very painful that it can even cause shock, fever, and lung and heart problems. Other jellyfishes like the giant jellyfish, no. The box jellyfish's venom can easily stop heart and systems functioning. But it is very weird how a lot of people say that blue ringed octopuses poison is strong enough to kill twenty to forty fully-grown humans at a time.
yeshhh or nooo go find out by getting inkk by a starfishh (LOL) IDK -------- actually several species deficate a type of dark matter that can render an predator blind. The Asian blue starfish can deficate up to twice its own body weight in dark mattter when required to do so.
Yes, a common octopus is a type of octopus
The Ringed Seal eats Cod and other fish. So, it is a carnivore
