Sand mullet facts are quite fun to read.

The sand mullet, also known as sand gray mullet, is a mullet species belonging to the Myxus genus. Found in coastal marine waters, Myxus elongatus fishes are situated around Australia and in the southwest Pacific. They do not dwell in the depths of the ocean, but instead swim and spawn in shallow waters.

These members of family Mugilidae are known to swim in large schools. This habit is adopted to reduce the probability of being eaten by any dangerous predators. Swimming in large schools confuse predators and deviate the larger predator. The predator might munch down on some mullets, however, the overall probability is reduced.

This mullet of Australia is a common commercial fish and has been consumed as meat and even used as bait for fishing. This fish has many other names such as black spot mullet, bully mullet, lano, and wide bay mullet.

The oxygen is taken from the water as the mullet exhales, and the water is pushed out through their pharynx. The blood in their bodies flows in the opposite direction over the gills. In this process, maximum oxygen is absorbed from the water.
