When does an octopus become a fire hazard?
When it is soaked in alcohol and left near a box of fireworks.
___
That is definitely true for a dead (or drunk) octopus, but for a regular everyday one, I find that they are more of a fire hazard because they are always panicking when you yell "Fire," and waving around their multiple arms and blocking the fire exits.
Yes, octopuses have relatively large eyes compared to their body size. Their eyes are essential for their hunting and survival in the ocean, providing excellent vision and the ability to detect even subtle movements in the water.
The telescope octopus, also known as the glass octopus, has a unique transparent body that allows it to blend in with its surroundings in the deep ocean. This transparency helps it evade predators and ambush its prey effectively. Additionally, its gelatinous body structure and lack of pigment help it remain nearly invisible in dimly lit environments.
Octopi are generally not disturbed by dim light, but they can be sensitive to bright light which might cause them to seek shelter or change color to blend in with their surroundings. In their natural habitat, they are usually more active during the night or in low-light conditions.
Is a octopus living or non living?
It's alive unless it's dead, in which case it's not going to be an octopus for long.
Are octopi also known as cuttlefish?
No. Octopi and cuttlefish are related, but they are not the same. Both belong to a class of marine invertebrates cephalopods, which also includes squid. One key difference is that squid and cuttlefish each have eight arms plus two tentacles while an octopus simply has eight arms.
Are octopus unicellar or multicellular?
Octopuses are multicellular organisms. They are complex animals with specialized cells that form tissues, organs, and organ systems. Their bodies consist of millions of cells working together to carry out various functions such as movement, digestion, and reproduction. Octopuses belong to the phylum Mollusca, which includes other multicellular organisms like snails, clams, and squids.
First the octupus catches its prey till it has full control over it. Secondly it bites it with its beak. The beak then makes its prey fall in a doze or sleep. Then since its prey does not try to escape the octopus eats it.
The male octopus uses a modified tentacle (this specialised arm is called a hectocotylus) insert spermatophores (packets of sperm) into the female's mantle cavity.
The hectocotylus in benthic octopuses is usually the third right arm.
Males die within a few months of mating.
I have observed octopuses mating and they can be quite far apart while the sperm exchange happens.
Octopi typically live in oceans and seas around the world, preferring shallow coastal waters. They are commonly found in rocky crevices, coral reefs, and seagrass beds where they can hide and hunt for food. Some species of octopi also inhabit deeper waters.
What is the kingdom phylum class order family genus species of the blue ringed octopus?
There are currently four species confirmed, with six more under research. Identified in 1929, they belong to the Animalia Kingdom and the Mollusca Phylum, the Cephalopoda Class and the Octopoda Order. They are in the Octopodidae family, and the genus of Hapalochlaena. The Blue-lined octopus species is Hapalochlaena fasciata (fasciata being the species part of the binomial), the Greater blue-ringed octopus is Hapalochlaena lunulata, the Southern blue-ringed or Lesser blue-ringed octopus is Hapalochlaena maculosa, and Hapalochlaena nierstraszi doesn't seem to have a "popular" name, though it was originally identified in 1938.
Are spiders and octopuses related through common ancestry?
Not closely: spiders are arachnids (a type of chelicerat), octopuses are cephalopods (a type of mollusk).
However it is believed that all living things do have an ultimate common ancestor, no matter how much they have diverged from each other.
What is the scientific name for north pacific octopus?
Octopuses are the most intellectual marine animals. They can memorize, mimic and solve problems in labs. There have been many cases in which octopuses escaped from their tanks. To answer your question correctly, the scientific name of the common octopus is Octopus vulgaris.
How many hearts does an octopus have?
Octopuses have three hearts. Two branchial hearts pump blood through each of the two gills, while the third pumps blood through the body.
Some are eaten by alligators and birds of prey will eat some of the smaller ones
Paul the Octopus, the magnificent octopus who predicted the games' outcomes in the 2010 FIFA World Cup, died of natural causes at the Oberhausen Sea Life Center in western Germany on October 26, 2010. The average life-span of an octopus is three years.
