Asian arowana refers to several varieties of freshwater fish all in the genus O. Scleropages. Some sources differentiate these varieties into multiple species,^[1][2] while others consider the different strains to belong to a single species, Scleropages formosus.^[3] They have several other common names, including Asian bonytongue, dragon fish, and a number of names specific to different varieties.

Native to Southeast Asia, Asian arowanas inhabit blackwater rivers, slow-moving waters flowing through forested swamps and wetlands. Adults feed on other fish, while juveniles feed on insects.^[4]

These popular aquarium fish have special cultural significance in areas influenced by Chinese culture. The name dragon fish stems from their resemblance to the Chinese dragon. This popularity has had both positive and negative effects on their status as endangered species.

Seahorses are a genus (Hippocampus) of fish belonging to the family Syngnathidae, which also includes pipefish and leafy sea dragons. There are over 32 species of seahorse, mainly found in shallow tropical and temperate waters throughout the world. They prefer to live in sheltered areas such as sea grass beds, coral reefs, or mangroves. Colonies have been found in European waters such as the Thames Estuary.^[5] From North America down to South America there are approximately four species, ranging from very small in size (dwarf seahorses are only about an inch long) to those much larger, found off the Pacific Coast of Central America (the foot-long Hippocampus ingens). Hippocampus erectus are larger seahorses found anywhere from Nova Scotia down to around Uruguay. Three different species of seehorse live in the Mediterranean Sea: Hippocampus hippocampus (long snout), Hippocampus brevirostris (short snout) and Hippocampus fuscus (immigrated from the Red Sea)^[6]. These fish form territories, with males staying in about one square meter of their habitat while females range about one hundred times that area. They bob around in sea grass meadows, mangrove stands, and coral reefs where they are camouflaged by murky brown and grey patterns that blend into the sea grass backgrounds. During social moments or in unusual surroundings, seahorses turn bright colors.

The Phyllopteryx taeniolatus, the weedy sea dragon or common sea dragon, is a marine fish related to the seahorse. It is the only member of the genus Phyllopteryx. It is found in water 3 to 50 m deep around the southern coastline of Australia, approximately between Port Stephens, New South Wales and Geraldton, Western Australia, as well as around Tasmania. Weedy sea dragons are named for the weed-like projections on their bodies that camouflage them as they move among the seaweed beds where they are usually found.
