The intriguing incident was captured on video by Jules Casey, a frequent poster of underwater footage on her Instagram account, OneBreathDiver.

The footage, shared through Storyful, shows the decorator crab slowly moving in front of the big-belly seahorse, its body adorned with sponges as a form of disguise. However, the seahorse remained unimpressed by the crab's efforts to blend in with its surroundings.

Commenting on the encounter, Jules Casey stated, "I filmed a decorator crab as it slowly moved in front of the big-belly seahorse... The decorator crab covers itself in sponges as a form of camouflage but it wasn't fooling the seahorse."

Decorator crabs, also known as carrier crabs or sponge crabs, are known for their unique behavior of attaching materials from their environment, such as sponges, algae, or debris, to their exoskeletons using velcro-like hooks. This adaptation helps them blend in with their surroundings and avoid detection by predators.

Big-belly seahorses, scientifically known as Hippocampus abdominalis, are one of the largest seahorse species in the world. They are native to the coastal waters of southern Australia, including Victoria, and can grow up to 35 centimeters in length. These seahorses are known for their distinctive large bellies and their role in male pregnancy, a unique feature among seahorses.

Despite the crab's best efforts to camouflage itself, the seahorse's keen observation skills proved superior in this instance, showcasing the complex relationships between predators and prey in the underwater world.
