Pictures of Fish Elephantnose Pictures and Elephantnose Fishes Kind

Elephantnose fish is an elephantfish native to the rivers of West and Central Africa especially in the lower Niger River Basin. They prefer muddy and slow moving rivers and pools with submerged branches. Elephantnose is the most commonly available aquarium fish in various aquarium stores throughout the United States.

Elephantnose has a dark brown to black laterally compressed body with a rear dorsal fin and anal fin of the same length. Their most striking feature is a elephant-trunk-like protrusion from their head. The protrusion is not actually a nose but a sensitive extension of the mouth that it used for self defense, communication, navigation and for finding their food items such as worms and insects. This organ and rest of the body is covered with electro-receptors. They have a very poor eyesight and hence they use a weak electric field for locating and catching their prey and for navigating in dark waters. They usually live from 6 to 10 years.

Bat Ray is an eagle ray fish that can be found in muddy or sandy sloughs, estuaries, bays, kelp beds and rocky-bottomed shoreline in the eastern Pacific Ocean between the Oregon coast and the Gulf of California. Largest specimens of bat ray can grow up to 90 kg with a wingspan of 1.8 meters. Bat rays can live in environment with large range of salinities. Currently, bat rays are fished commercially in Mexico but not in the United States.

Bat rays feed on mollusks, crustaceans and small fish on the seabed. They use their wing-like pectoral fins to move sand and expose prey animals. They can dig trenches up to 20 cm deep to expose buried prey. Like other stingrays, bat rays have a venomous spine in its tail near the base, which is not considered dangerous to human beings except when attacked or frightened. Bat rays are very popular in marine parks where the visitors are often allowed to touch or stroke ray, usually on the wing.

Australian Lungfish or Queensland lungfish is one of the only six extant lungfish species in the world. It belongs to an ancient family of fleshy finned species. It is one of the oldest living vertebrate genera on the planet. Australian lungfish is the representatives of six extant and ancient air-breathing lungfishes that flourished during the Devonian period (around 400 million years ago) and is the most primitive surviving member of this lineage. Australian Lungfish is generally a sedentary species that spends its life withing a restricted area.

Out of the five other fresh water lungfish species, four are found in Africa and one is found in South America. Australian lungfish can live out of the water for several days if it is kept moist. However, it cannot survive total water depletion unlike its African counterparts. They live in slow-flowing waters and rivers including water reservoirs that have some aquatic vegetation present on the banks. It can be found over mud, sand or gravel bottoms. Although Australian lungfish is tolerant of cold but it prefers waters with temperature 15 to 25 degree centigrades.
