Hi! Emma here with our weekly edition of Tidal Tuesdays! As we should all know by now, Marine Bio is my special interest! So today I am going to be talking about blue ringed octopus! A poisonous species of octopus.These little guys, are around the size of a golf ball, with a arm span of up to 20cm. They carry an extremely poten venom, but despite that, fatalities are rare.
Some more facts!
1.) Their venom contains tetrodotoxin, a powerful neurotoxin capable of causeing paralysis and respriatory failure in humans.
2.) They are defensive rather than aggressive to humans. Bites are rare and usually occur when handled.
3.) The blue rings act as a warning dispplay and intensify in colour when threatened or stressed.
4.) They have a single strong, parrot-like beak capable of piercing human skin.
5.) TThere may be around ten different species of blue-ringed octopus, though only four of them have scientific names.
6.) Scientists and experts aren't exactly sure of how many blue-ringed octopuses there are, so it's very unclear as to wether their populations are in decline, but irregardless human activities may still be affecting them.
And that is it!
