No, not even close. Note the taxonomy. First the octopus, then the spiders.
Kingdom: Animalia
Phylum: Mollusca
Class: Cephalopoda
Order: Octopoda
Family: Octopodidae
Kingdom: Animalia
Phylum: Arthropoda
Class: Arachnida
Order: Araneae
Major differences: no octopus can breath air, no spider can breath under water. Octopus are much large, spiders in comparison much smaller. Octopus do not have an exoskeleton, spiders do.

Octopuse is a type of mollusks not a underwater spider.
Any of numerous carnivorous marine mollusks of the genus Octopus or related genera, found worldwide. The octopus has a rounded soft body, eight tentacles with each bearing two rows of suckers, a large distinct head, and a strong beaklike mouth. Also called devilfish.

Octopuses belong to the phylum mollusca, spiders belong to the phylum arthtopoda. The only thing they have in common is a lack of a spine.

The octopus (Greek Ὀκτάπους, 'eight-legs') is a cephalopod of the order Octopoda that inhabits many diverse regions of the ocean, especially coral reefs. The term may also refer to only those creatures in the genus Octopus. In the larger sense, there are 289 different octopus species, which is over one-third of the total number of known cephalopod species.

No. But there are lots of underwater spiders in the seas and in pools on land.

Now, a real answer...
Octopi (that's more than one octopus) belong to the Phylum Mollusca. That means their relatives include organisms like squid, cuttlefish, chambered nautilus which are all cephlapods; and less closely to snails, slugs, and nudibranchs which are all gastropods; or clams, oysters, and mussels which all belong to Bivalvia.
Spiders belong to the Phylum Arthropoda which includes groups like insects (flies, ants), arachnids (spiders, mites, ticks), crustaceans (crabs, shrimp, barnacles).
Loosely, as far as evolution goes, octopi and spiders are about as distantly related as any two animals can be.

Yes because every time you flush a spider away it soon comes back as it is related to the octopus 2nd cousin twice removed and loves the water

No, they aren't! Spiders are insects, and octopuses are cephalopods. Octopuses are smart too, way smarter than any spider! :)

nope.
Spiders are related to crabs and lobsters, not octopi.
There are several species of freshwater diving spiders and several that "skate" on pond surfaces to hunt, but none such in the sea have yet been observed.
Cheers, Steve.
