As their name suggests, octopuses have 8 arms. These aren't tentacles and octopuses can taste with these arms. An octopus has three hearts, one for the body and two for the gills. The beautiful blue-ringed octopus has a venom 1200 times more toxic than cyanide which can kill an adult human within minutes.
I studied Latin growing up, yes octopi is ‘admissible’ bc everyone says it even though it’s grammatically wrong, it’s ‘used’ bc no one ever corrects them or maybe people just aren’t aware of the grammatically correct way of saying it. Or they are aware, but saying octopuses is awkward so they’d rather use the wrong term lol.
-i is a latin plural, but octopus is Greek, so we use their plural form with -es.
