Oarfish are large, greatly elongated, pelagic lampriform fish belonging to the small family Regalecidae. Found in all temperate to tropical oceans yet rarely seen, the oarfish family contains three species in two genera. One of these, the giant oarfish, is the longest bony fish alive, growing up to 8 m in length.

Body
oar fish have a slender and flattened scale-less body,, covered by a silver guanine wrap, as well as an
outstanding, medium-sized mouth. In addition, they have some weird accessories that give them a
strange appearance, full of a unique beauty, within so many marine species.
Fin:
They have a good-sized dorsal fin, which begins at the top of the eyes and reaches the end of the tail.
This is pink or red and has about four hundred thorns; twelve of them being slightly
elongated, which gives rise to the formation of a protruding and very striking red crest.
The pelvic fins as well as the dorsal ones have almost the same
elements, and their shape resembles an oar and hence the origin
of the species name. The pectoral fins are very small, almost
visible while the anal and caudal ones are extremely small,
almost absent.

 A ribbon-shaped fish, very thin from side to side, the oarfish may grow to a
length of about 9 metres (30.5 feet) and a weight of 300 kg (660 pounds).
 It is shiny silver in colour, with long, red, oarlike pelvic fins and a long, red dorsal fin
that rises as a manelike crest on top of the head.
 Seldom seen at the surface, it is credited as the “sea serpent” of some reported
sightings.
 They feed on krill or tiny plankton.
 They lack scales. Instead their bodies are covered with little bumps called tubercules.
 They are super shiny as their entire body is coated with a slivery like material called
guanine.
 Many marine biologists claims that they are weak swimmers. They are often found
hanging vertically in the water with their heads pointing up.
 Many historic tales describe them as sea monster but in reality they are toothless and
harmless

They can be found in the depths swimming
vertically although they can also swim
horizontally, due to their fairly good
locomotion system that allows them to perform
various maneuvers of change of speed and
direction..
These are shy and very calm fish that don’t like
to attract attention. When they are stalked by their
predators, oar fish tend to flee to the depths and
take refuge among the rocks

Oar Fish: Habitat and Distribution
Oar fish inhabit the depths about 1000 meters. Thanks to
their ability to adapt their body temperature to about twenty
degrees Celsius, they can be found in almost every ocean in
the world, except for polar areas.
They are usually a migratory fish, so they don’t stay long in an area.
However, oar fish can be found relatively easily in tropical regions
of the temperate oceans.
They move to great distances of different waters to look for food and
refuge and to flee from their predators being able to navigate from
depths of 20 meters to 1000 quickly

What do Oar fish Feed On?
The Regalecidae feed on plankton, squid, small fish and
crustaceans using their gills and the very well developed rakes
of their mouth, which are not observed with the naked eye, but
only when capturing their prey.
How do Oar Fish Catch their Prey?
Oar fish differ from sawfish because they lack teeth, so they
must use other means to catch their prey and feed. Everything
in these animals has a raison d’être, since they don’t not have
teeth, but fortunately they are provided with mouth gills
spines designed for such a rake-like activity, which unfold
from their gills. Another advantage for catching prey is
their vertical swimming way, which is quite useful.

How Do Oar Fish Reproduce?
The spawning occurs between July and December, during which time they
lay a larger quantity of eggs around 2.5 millimeters in diameter.
Such eggs are thrown towards the surface where they remain
floating until they reach the time of hatching.

Auto Amputation Skills
Oar fish have a very relevant characteristic, which is the capacity of self-amputation.
However, some doubts have not yet been clarified in this regard, despite the fact that many
media have given information about this event, stating that this fish bites its tail to amputate
it.
The latter is not very credible since they do not have teeth. What is more likely is that this
fish separates the final part of its body, (a fact that until now the reason is unknown), many
times throughout its existence.

The Oar Fish and Tsunamis
The appearance of these marine
creatures badly called sea
monsters triggers a horror
movie and bad omens, since it
is said that every time they are
observed an earthquake will
arrive.
A similar event occurred in 2011
in Haiti and Chile, where a
huge sea snake appeared and
after two weeks, the disastrous
tsunami occurred on the
Japanese coast.
