*internal Scooby monologue*

“Hey. Gang. Hey. Look at this.”

“No, over here. Look. Seriously.”

“See? It’s the Scooby Snacks that we need to touch to escape this virtual world. Same as all the previous levels.”

“Grab it, and we’re done here. Just grab it.”

“No, seriously, I don’t have opposable thumbs, it’s way harder for me. Could one of you just–… wait, what are you looking at?”

“Oh. A shark way off in the distance. Cool. I guess the whole gang can hear long-distance sharks underwater now.”

“You know It’s like 30 feet away, right? Just grab the Scooby Snacks and we’ll be teleported out of here.”

“I… what are you doing? You can literally just– oh, for the love of….”

“FINE! Fine. Here, I got them. Now we’ll fade away, and teleport to safety at the last possible second.”

👉Repost this if you’ve never heard of the Blanket Octopus!
🐙 The female blanket octopus is totally the wonder woman of the sea.
😯 The males? 10,000 times smaller & no epic cape! (This makes for an interesting first, and last, date.)
⚡️Young female blanket octopuses have been observed ripping the tentacles off of portuguese man-o-war jellyfish, whose highly venomous sting can be fatal. She grips the stingers with her suckers to stun and kill predators.☠️
🌊Blanket octopuses spend their whole life floating in the open ocean, and when threatened swoop down into deeper waters

Though sharks may seem scary or dangerous, most are extremely unlikely to even approach humans. 

Whitetip reef sharks, for example, tend to swim away when swimmers or divers approach. Here, a diver quietly observes a whitetip reef shark at French Frigate Shoals in Papahānaumokuākea Marine National Monument.
