Imploding Volcanoes

Did you ever wish you had a built-in blanket? Well, this cephalopod doesn’t need to wish… Meet the Indo-Pacific violet blanket octopus (Tremoctopus gracilis)! While males are tiny, rarely growing more than a few centimeters long, females are more than 10,000 times that size—reaching lengths of up to 6 ft (2 m)! Females also sport massive “blankets,” which are actually webs of skin connecting their dorsal arms. When threatened, they can drop these appendages, distracting predators as they make their escape. 

Have you ever seen the polka dot wasp moth (Syntomeida epilais)? This insect inhabits neotropical regions in parts of South America, Central America, and North America. It can grow up to 2 in (5.2 cm) long. Males and females both sport striking blue colors, with white spots and red-tipped abdomens. While these insects don’t sting like true wasps, they are toxic to predators. 

Down to the last second with this one! And we ended up with a tie in one of the matches, so we've got 3 finalists.

190: Mr Parker's Cul De Sac (5x07)

I'm surprised that cowboy Sara didn't crush the competition this time! Nearly taken out by a plain tank top! Anyway, this ensemble is from her trip back to the S3 finale with Ava to save Gary from Damien Darhk. Ava's corresponding outfit won her tournament. Will they match?

200: Freaks and Greeks, I Am Legends (5x12-5x13)

Sara's sorority party outfit, perfect for beating a literal god at beer pong. While temporarily blind.

207: Swan Thong, Ground Control to Sara Lance, Back to the Finale: Part II (5x15-6x01, 6x07)

I do sincerely apologize for the silly photo but there aren't a lot of full body images of this costume! Worn for a celebratory punk concert, an alien abduction, and several failed attempts to prevent the alien abduction at the punk concert.

"tens of thousands"

these ones are likely Mobula Munkiana
