Species Profile
Myxodagnus sagitta is a species of sand stargazer endemic to the Galapagos Islands where it can be found in areas with sandy bottoms at depths of from 18 to 46 metres. This species can reach a maximum length of 6.1 centimetres (2.4 in) SL.
The Arrow Stargazer faces significant threats from coastal development and habitat degradation throughout its range in shallow marine environments. Bottom trawling and other destructive fishing practices damage the sandy and muddy substrates essential for this species' burrowing lifestyle, while pollution from coastal runoff further degrades water quality in critical habitats.
Key Facts
Habitat & Distribution
Arrow Stargazers inhabit shallow coastal waters with sandy and muddy bottoms, typically found buried in soft sediments in bays, estuaries, and nearshore marine environments. They prefer areas with fine substrate where they can easily burrow and ambush prey from their concealed positions.
