▶ Your Answer :
In this given set of information, there is
some discrepancy between the views of the lecturer and the author from the reading
over the issue of the gulf sturgeon, an ancient freshwater fish in Florida’s
Suwannee River. With three cogent explanations, the lecturer raises objections
to the plausible theories on why these fish jump presented in the reading passage.
First
of all, the lecturer debunks the author’s first conjecture since it is disputable.
To elaborate in detail, the lecturer points out that gulf sturgeons do not eat
insects at the surface of the sea. Instead, they eat marine organisms at the
seafloor. On top of that, the fish only eat insects in a different part of the
ocean, during a different season. Thus, it is highly unlikely that the sturgeon
jump to eat insects. This view is diametrically opposed to the author’s
assertion that these fish jump in order to catch prey flying above the water as
they jump in the morning or in the evening when insects are most active.
In
addition, the lecturer also indicates dissent over the issue of dislodging of
parasites. The lecture sounds convinced that the author is making a manifest
error about the characteristics of parasites. He mentions that the gulf
sturgeon do not have large external parasite like suckerfish that are shed by
jumping although some other fish may do so. On the other hand, the author insists
that jumping helps the sturgeon to remove parasites such as lice or leeches because
sailfish shed off their parasite, suckerfish by jumping.
Thirdly,
the lecturer goes on to expound that the author’s final point is flawed. The
lecturer explains the example of boats is illogical and sounds like a story. He
confirms that there is no correlation between the fish’s jumping and the presence
of boats and it was merely by an accident. However, the author clarifies that
jumping is a response to invaders of the sturgeon’s territory by explaining
that large fish collide with the boats since the fish vie the boat as a threat.
