Marine Species
I have chosen to conduct a Power Point presentation on my Marine
Species assignment alone. My species is the Barrel-Eye Fish, otherwise known as
the Macropinna.
Kingdom:
Animalia
Phylum:
Chordata
Class:
Actinopterygii
Family:
Opisthoproctidae /Macropinna Microstoma
Some of the topics I will be discussing are;
Location: Deep Sea, N.E Pacific Ocean.
Bathylpelagic
Life
Span:
Unknown
Feeding
Behavior: When a study was conducted on Mesopelagic fish, which revealed the
content of their visceral anatomy, they were believe to feed on Cndarian
remains, zooplankton, gelatinous and crustacean prey.
What
do they prey on? They are believed to steal the food
from siphonophores. The will linger below and eat the scraps disbursed by the
jelly’s. Their dome-shape over their head is believed to protect them from their
poisonous tentacles.

What
preys on them?
Unknown
Does
it do Bioluminescence? Unknown
Mating
habits:
Oviparous w/ planktonic larvae.
How
large are they?
15 cm long
Other information obtained about Macropinna:
Transparent head
and tublar eyes.
Discovered in 1939
See’s bioluminescence of jellys and other small animals above,
by rotating its tubular eyes and swims upward to feed.
Eyes are good at collecting light.
Believed to have tunnel vision until one was captured with its
done still intact. At which point they concluded, Macropinna can rotate eyes
allowing them to see directly forward or straight up.
They are able to search for Silhouettes of food by looking
overhead.
Small pointed mouths.
Research study done by, Bruce Robinson and Kim Reisenbichler of
Monterey Bay Aquarium Research institute by using ROV’s (remotely operated
vehicles) 2,000-2,600 feet.
Eyes are filled by a fluid filled shield. This is fragile and
was destroyed for several years in attempts to bring Macropinna to surface.
The green pigments in its eyes help Macropinna to filter out
sinlight from the surface and to see food.
High numbers of rods in its eyes. Retinae allows them to resolve
silhouettes of prey in faint light, overhead.
