Fatos principais

Deep-Sea Dwellerbehavior

Beryx splendens is a true deep-sea fish, adapted to life in the aphotic zone where sunlight does not penetrate, hence its large eyes.

Global Distributioninteresting

Despite its deep-water habitat, Alfonsim has a remarkably wide, almost circumglobal distribution, indicating its adaptability to various deep-ocean environments.

Schooling Behaviorbehavior

This species often forms dense schools, particularly around seamounts and oceanic ridges, which makes it a target for commercial fisheries.

Longevityinteresting

Alfonsim can be a relatively long-lived species, with individuals reported to live for several decades, a common trait among deep-sea fish.

Commercial Importanceinteresting

It is highly valued in many markets, particularly in Asia, for its delicate flavor and texture, often fetching high prices.

Espécies similares

Imperador

Beryx decadactylus

Beryx decadactylus (Red Bream or Alfonsino) has a deeper body, a less deeply forked caudal fin, and typically a more uniform red coloration. Its dorsal fin spines are generally longer and more robust than B. splendens. The number of soft rays in the anal fin also differs (25-29 in B. decadactylus vs. 26-30 in B. splendens).

Slender Alfonsino

Centroberyx affinis

Centroberyx affinis is generally more slender and less deep-bodied than Beryx splendens. While also reddish, its eyes are proportionally smaller, and its geographic distribution is more restricted (primarily Australian waters).
