There’s nothing small about what fisherman Steve Bargeron caught when he was fishing from a deck in Fort Pierce, Florida.

Bargeron caught a shrimp that was far from its name. The giant shrimp was around 18 inches long and Bargeron said he had to grab it from its tail like a lobster.

According to the Florida Fish and Wildlife Commission, scientists said the giant catch could have been a form of mantis shrimp. However, a mantis shrimp isn’t actually related to shrimp; it’s actually a type of crustacean called a stomatopod.

Scientists haven’t been able to identify the exact species yet.
