Anglerfish and its secrets

About 70 per cent of the Earth's surface is covered by water, most of it forming the vast oceans. While we are familiar with marine animals such as dolphins, sharks and whales, many strange and rare creatures remain largely unknown.

One such mysterious animal is the anglerfish, which lives deep in the Atlantic Ocean where sunlight cannot reach. There are around 200 known species of anglerfish, most of which inhabit the dark depths of the sea.

One of the most fascinating features of the anglerfish is its unusual reproductive system, which plays a crucial role in its survival. Male anglerfish are much smaller than females, sometimes no larger than a human finger. During reproduction, the male bites the female and gradually fuses with her body.

Over time, the male loses its independence and becomes a permanent source of sperm for the female. In this process, the male essentially lives as a parasite, playing no further role beyond reproduction.

Anglerfish are typically dark brown or black, allowing them to blend into their surroundings. This camouflage helps them hunt in complete darkness. Female anglerfish use a glowing organ on their heads, known as a lure, to attract prey.

The light is produced by bioluminescent bacteria living inside the lure. Unsuspecting prey are drawn toward the light and are swiftly captured by the anglerfish's large jaws and sharp, saw-like teeth.

Much about the deep sea remains unknown, including many secrets of the anglerfish. Although strange in appearance, anglerfish play an important role in maintaining marine balance. Protecting ocean ecosystems is essential to ensure that such mysterious creatures do not disappear forever.
