Researchers captured 29 coconut crabs on the island of Okinawa, Japan, and subjected them to a clamp steel force sensor. The study found that the clamp force of these coconut crabs ranged from 29.4 Newtons to 1,765.2 Newtons. (By comparison, humans have a maximum bite force of 340 Newtons.) Because the coconut crab's clamp force correlates significantly with body weight, the researchers calculated that the clamp force of a coconut crab pincer weighing 4 kilograms could reach a staggering 3,300 Newtons. That's more bite force than most land animals like cheetahs, bears, and wild dogs.

But for another comparison, the gun shrimp surely tops the list:
While the pistol shrimp (pistol shrimp) is less than an inch long, it can produce up to 218 decibels of sound, generating a shockwave strong enough to knock out its prey (such as small fish, shrimp, and small crabs) before the pistol shrimp approaches its prey and kills them.
The inside of the crayfish's cheliped is fixed and has a cavity in it, while the outside is movable and has a columnar projection that fits into the cavity on the inside. When the gun shrimp closed chelipeds, the outer projection instantly inserted into the cavity, the extruded water column to about 32m / s speed forward, the impact of the surrounding water to produce air bubbles. These bubbles burst instantly under the pressure of the surrounding water (about 600μs), resulting in cavitation (Cavitation), emitting a loud explosion, accompanied by the generation of 4500 ~ 4700 ℃ high temperature, very close to the surface temperature of the sun (about 4800 ℃)

This is more than the pincer's clamping force? Is it about pincer force? If than out of pincer force, bird-tailed mantis shrimp said here are trash ah:
The bird-tailed mantis shrimp attacked the prey, it can be in one-fiftieth of a second to the front of the limb will be catapulted out of the maximum speed of more than 80 kilometers per hour, acceleration more than the combined 5.588-millimeter caliber pistol bullets, can produce a maximum of 60 kilograms of impact, the instantaneous friction generated by the high temperature and even make the surrounding water sparks of electricity. water sparks.
