Lancetfish possess a long and very high dorsal fin, soft-rayed from end to end, with an adipose fin behind it. The dorsal fin has 41 to 44 rays and occupies the greater length of the back. This fin is rounded in outline, about twice as high as the fish is deep, and can be depressed into a groove along the back.

Scientists are using lancetfish's unusual stomachs, which contain barely digested food items, to learn more about the creatures that make up the middle of the marine food web and about the pervasiveness of plastics in the ocean.

13 thoughts on “ The Short, Sad Career of USS Lancetfish ” Boat Guy November 3, 2016 at 11:38. While a sad story I would nominate CDR Richard O’Kane, the sub Skipper who was on the bridge for a night torpedo attack when one of his own torpedoes ran bad and sank the sub.

The lancetfish has a very obvious “prehistoric” appearance, with those fierce-looking, sharp teeth on its jaws and the sail on its back, reminiscent of that of some dinosaurs (although, in the lancetfish the sail is actually an enlarged dorsal fin). Even its scientific name has a dinosaurian sound to it (Alepisaurus ferox). lancetfish attack; lancetfish taste; lancetfish range; YouTube.

The Longnose Lancetfish, Alepisaurus ferox, feeds on cephalopods and have a great hesitation to attack when individually exposed to high model pattern

Lancetfish float in the water column, using their large eyes to scan for prey, which once detected, they attack using their forked tails for rapid bursts of speed, their large dorsal sails are likely used to maintain a stable trajectory toward their target, and their large mouths and teeth are used to subdue prey before it can escape. Since gelatinous muscles are not built for long chases, scientists suspect lancetfish are ambush predators, floating quietly camouflaged in the water until unsuspecting prey comes near enough to strike. NOAA scientists are looking at the stomach contents of lancetfish to understand the mysterious midwater food web. On 24 March 1945, USS LANCETFISH (SS-296) was decommissioned after serving the shortest-ever term as a commissioned naval vessel—just 41 days.
