The body is oval and stout with flattened
ends; H. scabra has prominent
wrinkles on its upper surface and is generally smaller and lighter that the versicolor variety.
H. scarbra has a grey to greenish upper surface with many fine black spots, and a creamy lower

Sandfish are found in many countries in the
Indo-Pacific, from east Africa to the eastern Pacific. They are usually found between the latitudes of 30°N and
The preferred habitats of sandfish are shallow tropical waters, usually less than 20m deep, such as sheltered areas
with high levels of nutrients, including muddy substrata and seagrass beds. They can tolerate reduced salinity (20
ppt) for short periods and so are sometimes found in brackish water. Its average density is about 100 animals per
hectare. They often spend part of the day buried in the silty sand.
