the strange apparition
of
cannibalistic fish
with teeth like daggers and extremely elusive, along kilometers of the coast, causes
bewilderment among biology experts.
Officials of the Oregon State Parks (OSP), USA, communicated on their social networks that specimens of
lancet fish
(
Alepisaurus ferox
) have appeared on the state's beaches in recent weeks.
The strange appearance and stranding of these notorious cannibalistic fish,
with giant eyes and dagger-like fangs
, along a 290-kilometre stretch of coastline has experts baffled.

How is the lancet or cannibal fish
According to information provided by the
US
National Oceanic and Atmospheric Administration
(NOAA)
, these fish live in tropical and subtropical waters at
depths between 200 and 1,000 meters.
They are known to migrate as far north as the Bering Sea to feed.
Also, they enlarge, growing up to
two meters long
and have a sail-shaped fin that extends almost the entire body.
Another distinctive feature is that it does not
have scales
, it has pores on its lateral line and its muscles are gelatinous, adds the
RT porta.

Confusion of biologists in the US
"No one is sure why they are coming to shore
," the OSP officials said from their Facebook profile.
Daniel J. Kamikawa
, a NOAA biologist, commented to
LiveScience
that "strandings in Oregon and elsewhere
are not exactly common or regular
."
The specialist suggests that among the possible explanations for these strandings could be
disabling diseases
, the drag effect
of storms
or a phenomenon known as temperature shock.
The reference in this last point has to do when a fish is suddenly exposed to a body of water that is much colder than its normal temperature range, they emphasize.

"This puts the fish
into 'shock'
and can greatly incapacitate and be fatal," Kamikawa said.
But, anyway, they are unproven theories and the appearance of cannibal fish, for sure, remains a mystery.
