'Invisibility' is rarer than gold in Vietnam

Fish razor (Solenichthys paegnius) belong to a family of fish with strange shapes, very difficult to imagine if only expressed in words .

They have relatively long, slightly flat bodies, large fins with large heads, very long snout, straw shape .

In general, their shapes and colors are identical to those of limbs that flutter on the seabed.

They also have the ability to change colors to suit the shelter environment.

They almost become 'invisible' with their excellent camouflage ability.

Razor fish is also a faithful fish, often living in pairs until the end of life.

This feature is similar to seahorses, a distant relative of razor fish.

This is a very rare fish. According to the Red Book, in Vietnam before 1995, people accidentally caught a child in Nha Trang beach, since then, they have not met again.

In the world, the species of razorfish family are very popular in marine aquariums. (Photo: Arkive.org)
