-__How many southern blue fin tuna are their__? Unknown, they are reproducing

- __Is the population increasing or decreasing__? They are increasing because we almost totally eliminated the species but now we caught it and make them reproduce and they are the 2nd faster reproducing endangered species today __Appearance__ The body color is blue-black on the back and silver-white on the flanks and belly, with bright yellow caudal keels in adult specimens.The first dorsal fin colour is grey with a yellow tinge, the second dorsal is red-brown, and the finlets are yellow with a darker border.



__Anatomy__- They are warm blooded, fish that are large streamlined fast swimming fish with caudal peduncle and relatively short dorsal, pectoral and anal fins.They have swim bladders, and their bodys are also covered in scales. They use suction feeding, and use their gills to take oxygen out of the water. The sothern bluefin tuna eats a wide variety of animals such as fishes, crustaceans, cephalopods, salps. They are eaten by sharks, squid and other large animals in the ocean. The main reason why these fish are getting exterminated is the high demand for tuna but we have slowed down production to let this species increase in numbers. They have breeding farms for these tuna and they are increasing the 2nd fastest out of extinct animals.
