How does a mudskipper catch small crab?

Mudskippers are fascinating amphibious fish found in mangrove swamps and mudflats along tropical coasts. They possess unique adaptations that allow them to catch small crabs in their muddy habitats. The process of catching small crabs involves several skillful techniques employed by mudskippers:

Sight Hunting:

Mudskippers have excellent eyesight, which enables them to spot small crabs from a distance. They patiently perch on mudflats or mangrove roots, scanning the environment for potential prey.

Quick Movement:

Once a mudskipper locates a suitable crab, it swiftly moves toward it. They can run on land using their strong pectoral fins and jump with remarkable agility to cover short distances.

Accurate Targeting:

Mudskippers have a remarkable ability to accurately target their prey. As they approach the crab, they precisely calculate the distance and angle to ensure a successful strike.

Water Jet:

When in close proximity to the crab, the mudskipper takes advantage of its unique capability to shoot a powerful jet of water from its mouth. This water jet has two primary functions:

- Stunning the Crab: The force of the water jet can temporarily disorient or even paralyze the crab. This gives the mudskipper an advantage in capturing its prey.

- Flushing the Crab Out: Mudskippers often employ the jet of water to flush crabs out of their hiding spots. Crabs are highly sensitive to water disturbances and quickly scamper away from the water jet, making them more exposed and easier to catch.

Rapid Capture:

As the crab is flushed out or momentarily stunned, the mudskipper quickly seizes the opportunity to capture it with its sharp teeth. Mudskippers can swiftly grab the crab with their specialized jaws and consume it whole.

Throughout the entire process, mudskippers demonstrate exceptional coordination, precision, and accuracy in catching small crabs. These remarkable abilities have evolved over time, allowing mudskippers to thrive in their unique habitats and efficiently obtain their primary source of food.
