Habitat and Ecology
The sexes are separate among the acanthurids (Reeson 1983). Acanthurids do not display obvious sexual dimorphism, males assume courtship colours (J.H. Choat pers. comm. 2010).

The catch composition of the Apo Island fishery in the Philippines is dominated by a few fish families, Acanthuridae being one of the five families accounting for about 50-90% of the catch. Reef and reef-associated species became more dominant in the catch over the years. In particular, an increasing proportion of carangids and acanthurids was observed in the catch over time. The proportion of Acanthuridae total catch almost doubled over the study period (16% in 1980/81 to 27% in 2000/2001) (Maypa et al. 2002).
In Kenya, landings during 1978-2001 for families that are less important in commercial catches (e.g., scarinae and Acanthuridae) showed rising catches (1978-1984) followed by a general decline during the 1990s, but the landings for the scarinae showed a rising trend in recent years (Kaunda-Arara et al. 2003).
Surgeonfishes show varying degrees of habitat preference and utilization of coral reef habitats, with some species spending the majority of their life stages on coral reef while others primarily utilize seagrass beds, mangroves, algal beds, and /or rocky reefs. The majority of surgeonfishes are exclusively found on coral reef habitat, and of these, approximately 80% are experiencing a greater than 30% loss of coral reef area and degradation of coral reef habitat quality across their distributions. However, more research is needed to understand the long-term effects of coral reef habitat loss and degradation on these species' populations. Widespread coral reef loss and declining habitat conditions are particularly worrying for species that recruit into areas with live coral cover, especially as studies have shown that protection of pristine habitats facilitate the persistence of adult populations in species that have spatially separated adult and juvenile habitats (Comeros-Raynal et al. 2012).
Relevance to Humans and Ecosystems
Naso thynnoides is a tropical fish found in coral reefs in the Pacific and Indian Oceans. It is commonly known as the oneknife unicornfish, oneknife unicorn, thunny unicornfish, singlespine unicornfish, one-spine unicorn, or barred unicornfish. It is of value in commercial fisheries, and is also used in aquaria.
