Alien Shrimp?

While fishing off the coast of Fort Pierce, Florida, Steve Bargeron saw a couple nearby pull up an oversized shrimp-like specimen that he jokingly called an "alien creature" that was wildly flopping its tail.

That "alien creature" is actually a type of mantis shrimp, probably a species Lysiosquilla, according to Roy Caldwell, a professor of integrative biology at the University of California, Berkeley. And like other Lysiosquilla species, this one showed off three pairs of walking legs and a large, articulated abdomen, Caldwell said. [Read full story]

Though Bargeron estimated the beastly shrimp caught off Florida was a whopping 18 inches (46 cm) long, species of Lysiosquilla typically only grow to about a foot long, Caldwell said, adding that he doubted the catch really reached that size. Bargeron noted he didn't have a measuring tape to record the size of the catch. [Read full story]

Mantis Shrimp Close-up

Mantis shrimp live in burrows on the seafloor and rarely come out, with some females never leaving such hideouts, Caldwell said. Here, a male mantis shrimp.

Largest Mantis Shrimp

The distinction for the largest stomatopod species goes to Lysiosquillina maculata (shown here), a mantis shrimp that lives in the Pacific Ocean from Hawaii to east Africa. The largest individuals in this species can grow to a whopping 15 inches (40 cm) long.

Crazy Eyes

Here, a juvenile peacock mantis shrimp, Odontodactylus scyllarus, showing off its googley eyes and hammerlike claw that can smash prey with the acceleration of a 0.22-caliber bullet. This species sports 12 different types of photoreceptors when four to seven are all that is needed.
