-- This week a few lucky fisherman managed to snag a few unusual catches of the day.
In Fort Pierce, Fla., Steve Bargeron got more than he bargained for when he was fishing off of a dock and snagged a giant mysterious sea creature.
As another fisherman started to pull in a large odd shaped shellfish, Bargeron thought it looked like a large lobster and pulled out the crustacean, only to reveal an 18-inch shrimp-like creature.
While the creature may have been unusual looking, the Florida Fish and Wildlife Conservation Commission said it was not some unknown species from the deep ocean but likely a member of the mantis shrimp family.
That odd crustacean, wasn't the only unusual shellfish caught in the U.S. this week.
In Maine, not one but two albino lobsters were caught by lucky fishermen. The pearly white crustaceans are exceedingly rare and the odds of catching a single albino lobster are nearly 1 in 100 million, according to the University of Maine's Lobster Institute.
The rare ghostly lobsters were caught by fishermen from the Owls Head Lobster Company in Owls Head, Maine. One of the lucky lobstermen, Joe Bates, told ABC News affiliate WMTW-TV in Portland, Maine, that he had named his unusual catch "Ronald" after President Ronald Regan because the odd looking lobster is a "survivor."
But odd looking shellfish weren't the only big catches of the week, a father and his two teenage sons out fishing for swordfish got more than they bargained for after snagging a fish weighing nearly 700 pounds.
Brian Sattar, of North Palm Beach, Fla., was with his sons Eric and Adam when they hooked the giant swordfish. For four hours the trio fought to pull the fish to the surface.
Brian Sattar said they weren't sure if they had caught a swordfish or a shark at first and they spent a few hours concerned they were going to lose the catch altogether.
"[We] still didn't know if it was a swordfish," Sattar said of the hours long fight to reel in the fish. "[But we thought] it's been this long, let's see what's going to happen."
Eventually the three fishermen managed to reel in the mammoth fish, but it was so large -- 14 feet long -- they couldn't fit it on the boat.
Sattar said his son Adam wanted to jump in and tie a rope around the fish's tail so that it would be more securely attached to the boat as they drove in. But Sattar said the task was too dangerous for the 17-year-old boy, so he jumped in instead.
"I jumped in and tied the rope around the tail," Sattar said. "When you're fishing out the in ocean every shark in the area knows something is going on. The shark knows something is struggling."
Once the family got back to the marina, a crowd gathered to watch the fish get pulled onto the dock and weighed. While Sattar said he thought the fish would weigh in at around 400 pounds, it actually weighed in at 693.8 pounds.
With nearly 40 to 45 people on the dock, Sattar said the fish was then filleted and handed out to anyone who wanted some. Sattar estimated that around 500 pounds of fillets were handed out.
