Summary

Description

The scaldfish is a flatfish with an oval body shape. It is very thin, almost transparent. The mouth is to the left of the eyes and rather curved. The eyes are relatively small and close together. The pelvic fin on the blind side has a much shorter base than that on the eyed side. It is brownish or greyish in background colour, usually with diffuse darker marks. The fins often have small dark spots. The pelvic fin on the eyed side sometimes has a dusky spot. The males are distinguished by the elongation of certain fin rays which gives the fish a quite unusual appearance. The scaldfish grows up to 25 cm in length.

Recorded distribution in Britain and Ireland

The scaldfish can be found on all British and Irish coasts although it is mostly recorded from the south where it is more common.
