Observations on two live specimens of Trachipterus arcticus (Lampriformes: Trachipteridae) from the Azores
During a 950 m depth submarine-dive South of Pico Island (Azores) an adult Trachipterus arcticus (Brünnich, 1788) was observed for about 50 seconds. Additionally, a small specimen of the same species with some larval characters was observed near to the surface in the harbour of Horta (Faial Island, Azores). This specimen was caught and observed for 45 minutes in an aquarium. We are reporting here the respective observations on live colouration, external characters, swimming and luring behaviour.
