It's no secret... I love sharks. They fascinate me~!
While I'm not close to being a shark-fishing expert, I've caught my share. It's usually a messy experience with lots of knotted line and bent hooks. Grabbing a wriggling shark is a tricky deal -- watch out for the sharp end! Getting the hook out of their very leathery skin is another deal that requires pliers and a strong hand. Fortunately, sharks are hardy creatures, and I've released all alive.
This video is really cool. Blacktip Sharks doing what they are built to do in a swift, tenacious, and aggressive manner. Quite a show.
No worries, the hooks were removed, so no sharks were harmed or landed. Heck, I don't think I'd want to land one of those fishes! I'd probably loose a finger... or two ;)

The Earth is flush with many spectacular rituals and phenomena. Think: mass coral spawning, Northern lights, phosphorescence.
Migrations have always intrigued me. When a Rubythroat Hummingbird recently showed up at my front porch looking for the jar of nectar I keep hanging each summer, I thought: "Holy COW! That little bird came all the way from MEXICO and REMEMBERED how to get back to this very spot in VIRGINIA!" I quickly prepared a new batch of nectar, hung it on the porch, and sure enough, the little bird returned again.
Fish migrations are another source of wonder. Think about it: Salmonids hatch in rivers (sometimes miles upstream), move offshore, and return to the very same stream to spawn as adults. American Eels make the opposite migration.... adults spawn somewhere in the Sargasso Sea, and their offspring move inshore and upstream until maturity. Other fish migrations remain a mystery. To this day, no one knows for sure where Great White Sharks spawn, or really why they travel such long and seemingly random distances.
Shads (collectively called "River Herring") are anadromous and a vitally important link in the food web. They used to have unimpeded pathways to their spawning grounds. When the rivers they traveled were dammed, their numbers plummeted. Aside from the dams and natural predators, they also had to overcome pollution, siltation, water withdrawal, and over-fishing. Today, some of those dams have come down, and other dams have been modified to include fish ladders. It's been proven that once a dam comes down, the fishes return almost immediately! Amazing.... An internal GPS and a drive to reproduce is hard-wired into the fish's DNA and cannot be suppressed, even by a dam.

|Original 1898 illustration showing protruding jaws (feeding/gulping position)|
|This is what their jaws look like most of the time.|
When the David Starr Jordan described the Goblin Shark in 1898 goblins were likely still a part of the culture and lore of the time. I don't know if he coined the common name, or if it was assigned at a later date. The scientific name, Mitsukurina owstoni, honors Mr. Allen Owston who secured the first specimen from a fisherman off Japan, and Professor Keigo Mitsukuri who passed the specimen on to Jordan for official description. It is a fitting and honorable name. The unattributed common name, however, cast a spell upon the shark which remains today.
When a specimen was recently caught in a trawl net off of Australia, it was variously called "evil, vile, creepy, ugly, terrifying, disturbing, hideous." NBC news said it can also be found "in your nightmares." Inaccurate descriptors surely meant to drum up attention and feed the public's thirst for drama. The only adjectives to accurately describe it are "prehistoric," and "living fossil," as those are true.
The Goblin Shark is a rare shark indeed, and from one of the oldest lineages of Elasmobranchs. It is one-of-a-kind and the only species within its genus. It is dissimilar to all other sharks with an elongate snout and highly protrusible jaws. It's soft body allows it to live at crushing depths. It occurs in scattered circumglobal locations over deep continental shelves, upper slopes, and around sea mounts to about 4,200 ft. Encountering one in your annual trip to the beach is less likely than winning the lottery.
While I doubt the common name will change in my life time, it would be refreshing to see it done. Heck, the American Fisheries Society renamed the Jewfish~! Why not rename the Goblin Shark? Such a cool fish deserves a more flattering moniker.
