Distribution & Habitat

Firehead by Mochi

Holids are found primarily tropical oceans above 30 degrees Celsius. Most species inhabit waters around tropical reefs or areas around 100 metres deep or shallower. The majority of holids are found on Osao, including the type species, Holis superis.

Larger species are more territorial, claiming small sections of a coral reef. They will decorate their territory with shells of a specific colour.

Anatomy

Glossy Holehead by Mochi

Holids have an rounded to elongated body shape, rarely growing more than 50cm in length. Holids have miniscule ctenoid scales which aren't visible from afar.

Their signifying characteristic is the hole above their spinal cord. This hole ranges in size in species, but typically sits between the head and dorsal fin, or in place of the dorsal fin (e.g. Magnuai asetia). This hole helps with circulation and can gather oxygen particles found in water.
