Meet the threadfin snailfish, Careproctus longifilis—midwater marvel and world-famous TikTok influencer. ⁠ ⁠ Snailfishes (family Liparidae) are a diverse and thriving group of fishes with over 400 described species. Their pelvic fins are modified to form a suction cup allowing them to fasten onto rocks, corals, or research equipment, and hold tight in strong currents. MBARI’s remotely operated vehicle got a great view of this snailfish’s suction cup. ⁠ ⁠ These deep-sea snailfish are found at depths between 1,900 and 3,334 meters (6,230 and 10,940 feet) and measure up to 15 centimeters (about six inches long).
