Larval Philippine Mantis Shrimp
In a recent study, released Thursday the 29th of April in the Journal of Experimental Biology, experts studied larval Philippine mantis shrimp -
Gonodactylaceus falcatus gotten originally from Oahu, Hawaii.
The team also nurtured some of the similar species from eggs, carefully observing their development through time and then magnifying their punching appendage with the use of a microscope.
The appendage, known as the raptorial appendage, works the same way a bow and arrow works, in that the tip of the appendage gets drawn back, nocked against a mechanism that is spring-like, and then let loose in a quick elastic energy release, said a graduate student in the biology program at Duke University, first author Jacob Harrison.

A U.S. Navy guided missile destroyer targeted a simulated enemy ship at a range of more than 250 miles.
The destroyer relied on targeting data supplied by uncrewed ships and aircraft.
Using drones to act as scouts for the crewed ship allows the warships to remain hidden, protecting them from enemy attack.
The U.S. Navy guided missile destroyer USS
John Finn recently achieved what could be the farthest anti-ship missile shot ever all with the help of drones.

John Finn, acting on targeting data provided by uncrewed air and sea platforms, struck a simulated target at more than 250 miles. The use of drones for targeting purposes will allow the Navy to detect, track, and destroy enemy targets at long distance without exposing friendly ships to enemy sensors.
