A couple in Florida, who went on a regular fishing date, caught a monster shrimp.
While on a fishing trip off a dock in Fort Pierce, Florida, fisherman Steve Bargeron spotted a couple with a strange looking alien sea creature, Livescience reported. The sea monster looked very much like a lobster.
"The couple wasn't interested in keeping the strange, lobster-like animal, which was flapping its tail wildly" Bargeron told the website.
The fisherman took a few pictures of the rare shrimp before throwing it back into the lake.
Roy Caldwell, an integrative biology profession told LiveScince that the strange looking specimen is nothing but an over-sized mantis shrimp or stomatopod which is a common sea dweller in Florida.
"This particular group is Lysiosquillidae and are almost all banded yellow and black across their bodies. They can live for 30 years and can grow to be 12 inches (30.5 centimetres) long, Caldwell told the website.
However, he agreed that a specimen of the Lysiosquillidae family as huge as the one the couple caught off Florida is quite unlikely.
The scientist claims to have studied stomatopods for 50 years, and an 18-inch catch is strange as the last known largest mantis of the same species was15 inches long.
Bargeron, the fisherman, said that he didn't have a measuring tape to record the exact size of the alien shrimp.
