MOLAThe Sun in Blue Depth

The ocean sunfish is
the largest bony fish
species
Bony fish have skeletons of bone, which distinguishes them from cartilaginous fish, whose
skeletons are made of cartilage. With their large eyes and relatively small mouth, the ocean
sunfish shown here almost looks surprised at its size!
1The largest ocean sunfish ever measured
was over 10 feet across, and weighed
close to 5,000 pounds. On average,
ocean sunfish weigh about 2,000 pounds.
This makes them the largest bony fish species.
Bony fish have skeletons of bone, which
distinguishes them from cartilaginous
fish,whose skeletons are made of
cartilage.
With their large eyes and relatively small
mouth, the ocean sunfish shown here

The ocean sunfish
may also be called
the Mola mola 2
The ocean sunfish's scientific name is Mola mola.
โ€˜Molaโ€˜ is Latin name for millstone,
which is a large, heavy round stone used to grind grain.
So, the ocean sunfish's scientific name is a reference
to the fish's disklike shape.
This species may also be called the common sunfish,
as here are other species of sunfish that live in the ocean
3 to be exact the slender mola (Ranzania laevis),
sharp tailed mola (Masterus lanceolutus)
and southern ocean sunfish (Mola ramsayi).
Ocean sunfish
don't have a tail.
3When you look at an ocean sunfish, you might notice that it appears
that its back end is missing. These fish don't really have a normallooking tail.
Instead, they have an appendage called a clavus, which is a result of the fusion of dorsal and anal fin rays.
Despite their lack of a powerful tail, ocean sunfish are capable of breaching (leaping) clear of the water!

Ocean sunfish may
be brown, gray, white
or spotted in color.4
An ocean sunfish's color can vary
From brown to gray or silvery,
or even almost white.
They may also have spots,
like the
fish shown here.
The preferred food of
ocean sunfish are
jellyfish.5
Ocean sunfish like to eat jellyfish and
siphonophores (relatives of jellyfish).
They will also eat salps, small fish,
plankton, algae,
mollusks, brittle stars.
Ocean sunfish are
found throughout
the world.6
Ocean sunfish live in tropical and temperate waters, and they may be found in the
Atlantic, Pacific, Mediterranean and Indian Oceans. To see an ocean sunfish,
you'll likely have to find one in the wild, though, because they are difficult to keep
in captivity.
Sunfish may look
Like they're 'playing dead'
7
There are a few theories on why sunfish do this. They may undertake long, deep dives in cold water in search of their
favorite prey, and may use the warm sun at the surface to reheat themselves and aid digestion
(research published in 2015 lent more support to this theory).
They may also use the warm, oxygen rich surface water to recharge their oxygen stores. And most interestingly, they
may be at the surface to attract seabirds from above or fish frombelow to clean their skin of parasites.
Some sources suggest that the waving of the fin is what is used to attract the birds.
Sunfish may spend more time at the
ocean surface at night.
8
From 20052008, scientists tagged 31 ocean sunfish in the North Atlantic in the first study of its kind.
This study made many interesting discoveries about ocean sunfish the tagged sunfish
spent more time at the ocean surface during the night than during the day, and
spent even more time at depth when they were in warmer water,.
The researchers proposed that this might be due to spending more time at depth looking for food
when the fish were in relatively warmer water.
Ocean sunfish are one of the most fertile species
One ocean sunfish was found with an estimated 300 million eggs in her ovary.
This is more than ever found in any other vertebrate species. Although sunfish produce lots of eggs,
the eggs are tiny, and are basically scattered into the water, so their chances of survival are relatively small.
If an egg is fertilized, the embryo grows into a tiny, spiked larvae, that even has a tail.
It hatches at about 2mm in size, and eventually the spikes and tail disappear and
the sunfish looks like a small adult.9
Ocean sunfish are not
dangerous to humans.10
Despite their enormous size, ocean sunfish are harmless to humans. They move slowly, and in fact are likely more
threatened by us then we are of them since they are not considered a good food fish in most places, their biggest
threats are likely being hit by boats and being caught as bycatch in fishing gear. As far as natural predators, parasites,
orcas, and sea lions seem to be the biggest culprits.
