This unusual fish is possibly a source for sea monster legends as its ribbon-like body can grow to 36 feet long in some cases. The long, flat, tapering body is reflective silver with a dorsal fin running the length of it that it uses to swim and turn with. Its abrupt, slightly concave profile is set with a toothless mouth ideal for filtering krill and crustaceans out of the water. It is a deep-water fish that spends time floating vertically in the water column to camouflage itself, trailing the elaborate red first spines of its dorsal fin and pelvic fins.
