Whale - Fish species existed since prehistoric times

Barramundi (scientific name: Pristiformes), is a stingray, characterized by a long cartilage in the muzzle, surviving from the Cretaceous and they can be found in good saltwater areas. in rivers and canals. They are 7 meters long, with 'saws' that are both weapons and sensory organs that help them feel their prey. Garlic fish can become extremely dangerous if provoked.

>>>The giant swordfish species in Australia

Barramundi only live in shallow and muddy waters, which can be found in both freshwater and saltwater areas. All species of swordfish are capable of moving back and forth between freshwater and saltwater areas.

The most special feature of the swordfish is the long muzzle section of the saw blade. The muzzle is covered with sensitive pores that allow the swordfish to detect the movements of the hidden prey on the seabed. It was also used as a digging tool to search for crustaceans and self-defense weapons, against the hunting of humans and predators like sharks."Teeth" protrudes from the muzzle not as real teeth, but they are transformed teeth-like structures, called "small teeth".

The body and head of the swordfish are flat, and they spend most of their time lying on the seabed. Their mouths and nostrils are located on the underside like stingrays. The mouth is lined with small, domed teeth to eat small fish and crustaceans. Breathing fish with two breaths behind the eyes. The skin is covered with a tiny layer of skin with skin, creating a rough texture. The rays are usually light gray or brown, particularly the Atlantic small rays (Pristis pectinata) are olive green.

Like other elasmobranchii species, gaur fish lack bubbles and they control buoyancy with a large oil-rich liver. Their skeletons are composed of cartilage. The eyes of the swordfish do not grow due to the mud habitat. The main sensory device of the swordfish is the muzzle. The intestine is shaped like a corkscrew, called a spiral valve.

All species of swordfish are considered extremely dangerous. They were hunted by accident, by hunting for their saw-shaped snout (possibly due to curiosity about them), fins (a delicious dish), and liver oil used in medicine. learn folk.
