Biology     Glossary (e.g. epibenthic)

This species is the most common istiophorid in the central basin of the Mediterranean and completes its life cycle inside this sea as far as is known to date. Probably swims in the upper 200 m water layer, generally above or within the thermocline. Travels in pairs, possibly corresponding to a feeding behavior. Feeds on fishes. Probably more widespread in the Mediterranean Sea and may have been identified as T. albidus by anglers and fishermen.

IUCN Red List Status (Ref. 115185)
