Tiny Freshwater Fish the Color of Outer Space

video upload by Joseph Ricketts

"I spent the day exploring a spring looking for one of Florida's most beautiful freshwater fish - the Gulf Coast Pygmy Sunfish. Pygmy sunfish may be tiny but boy are they ever vibrant, and with the help of my macro lens I was able to film some pretty sweet behavior from these feisty little fish. Although we often focus on charismatic megafauna like manatees when it comes to springs conservation, there's an incredible array of diversity that often gets overlooked. All the more reason to protect freshwater systems like Florida Springs."

Published on Oct 26, 2016 Monterey Bay Aquarium Research Institute (MBARI)

"Video observations of Hydrolagus cf trolli, the pointy-nosed blue ratfish, from the Northeast Pacific ocean represent a range extension for the species and are the first ever of this animal alive, in its natural habitat. The species was originally described from specimens collected off New Caledonia in 2002. It was named in honor of Alaskan artist Ray Troll because of his fascination and appreciation for this strange group of fishes known as chimaeras."

The first bright green fluorescent fish ever recorded in the wild, their discovery dates back to 2011, when a tiny eel photobombed David Gruber off Little Cayman Island in the Caribbean."

Pocket Sharks

via NOAA FISHERIES

"NOAA and Tulane researchers identify second possible specimen ever found

A very small and rare species of shark is swimming its way through scientific literature. But don’t worry, the chances of this inches-long vertebrate biting through your swimsuit is extremely slim, because if you ever spotted one you’d be the third person to ever do so.

This species common name is the “pocket shark,” though those in the field of classifying animals refer to it by its scientific name Mollisquama sp., according to a new study published in the international journal of taxonomy Zootaxa. While it is small enough to, yes, fit in your pocket, it’s dubbed “pocket” because of the distinctive orifice above the pectoral fin--one of many physiological features scientists hope to better understand.

“The pocket shark we found was only 5 and a half inches long, and was a recently born male,” said Mark Grace of NOAA Fisheries’ Pascagoula, Miss., Laboratory, lead author of the new study, who noted the shark displayed an unhealed umbilical scar. “Discovering him has us thinking about where mom and dad may be, and how they got to the Gulf. The only other known specimen was found very far away, off Peru, 36 years ago.”

Interestingly, the specimen Grace discovered wasn’t found it the ocean, per se; rather in the holdings of NOAA’s lab in Pascagoula. It was collected in the deep sea about 190 miles offshore Louisiana during a 2010 mission by the NOAA Ship Pisces to study sperm whale feeding. Grace, who was part of that mission after the rare shark was collected, and upon uncovering the sample at the lab years later, recruited Tulane University researchers Michael Doosey and Henry Bart, and NOAA Ocean Service genetics expert Gavin Naylor, to give the specimen an up-close examination."
