Tag: Lagoon Damselfish (Hemiglyphidodon plagiometopon)

Although only reaching a maximum length of around 20cm, the Lagoon Damselfish (Hemiglyphidodon plagiometopon) could probably be regarded as the most aggressive and ill-tempered fish species in local waters!!

With the Titan Triggerfish (Balistoides viridescens) holding almost legendary status as THE fish to be avoided at all costs, the Lagoon Damselfish enjoys almost complete anonymity in which to perpetrate its attacks on unwary divers...

The Lagoon Damselfish is fairly easy to identify with its overall drab, dark brown colouration and large scales.

When aggressively challenging intruders in its territory, the head and forebody rapidly changes to a light brown/tan colouration. The fin rays and margins may be deep blue in colour and there may be small lavender coloured spots or lines below the eye, although these are very indistinct and often require a close-up photograph to be seen.

In Damselfish terms, this is a relatively large species which leads a generally solitary existence within its territory. It can be found at most of the shallow inshore reef systems in the area, although its abundance varies significantly from one area to another.

Lagoon Damselfish (Hemiglyphidodon Plagiometopon)

This Lagoon Damselfish (Hemiglyphidodon Plagiometopon) was reasonably easy to get in frame as it was so busy attacking the camera at the time!!

Not content with viciously biting me on the thigh as i swam innocently by, it proceeded to head-butt, and even tail-butt the camera lens by backing into it repeatedly...
