Arowana Sea Creature

Arowanas are freshwater bony fish of the family Osteoglossidae, also known as bonytongues. In this family of fish, the head is bony and the elongate body is covered by large, heavy scales, with a mosaic pattern of canals. The dorsal and the anal fins have soft rays and are long based, while the pectoral and ventral fins are small. The name "bonytongues" is derived from a toothed bone on the floor of the mouth, the "tongue", equipped with teeth that bite against teeth on the roof of the mouth. The arowana is a facultative air breather and can obtain oxygen from air by sucking it into the swim bladder, which is lined with capillaries like lung tissue.

Anura Sea Creature

The name, Anura, meaning "without tail," identifies one of these: with one exception (Ascaphus), adult frogs do not have tails. Anurans represent, by far, the most speciose, diverse, and widespread of the three extant amphibian orders. They are found throughout most of the world, except in polar regions, and some oceanic islands and extremely xeric deserts. Anuran diversity is greatest in the tropics. Twenty-five families are currently recognized, representing more than 4,000 species, with more being discovered regularly. This clade is also referred to as Batrachia and is placed in superorder Salientia.

Angelfish Sea Creature

There are around 100 different species of angelfish that inhabit the waters of the southern hemisphere. There are two main types of angelfish, those that live in the freshwater rivers in South America (freshwater angelfish) and those angelfish that inhabit the salty ocean waters (marine angelfish).

Anemone Sea Creature

Anemone is a genus of about 120 species of flowering plants in the family Ranunculaceae, native to the temperate zones. It is closely related to Pulsatilla ('Pasque flower') and Hepatica; some botanists include both of these genera within Anemone.
