Family Gonostomatidae - lightfishes

Although lightfishes are abundant, their small size and deep water habitat makes observations rare except by research vessels. They are found worldwide in all temperate and tropical seas.

Remarks: These mesopelagic species sometimes enter the bay during strong tides. Most remain unnoticed due to their small size and low abundance. Large schools are common outside the bay in offshore waters.
