Filefish vs Triggerfish: common questions
Are filefish and triggerfish closely related?
Yes, both belong to the same taxonomic order and share a similarly shaped single dorsal spine, though they are distinct families with very different primary defence strategies.
How do filefish and triggerfish defend themselves differently?
The filefish relies mainly on camouflage, using a thin, leaf-shaped body and swaying motion to blend into seagrass and soft coral, while the triggerfish instead relies on a locking dorsal spine and a powerful, defensive bite.
Which family has more species, filefish or triggerfish?
The filefish family is somewhat larger, with around 100 species, compared to roughly 40 species within the triggerfish family.
