Paul
: Well
I suppose
it is to a certain degree. Scientists can hear all kinds of
sounds grunting, crackling, buzzing. It
turns out
that the ocean is quite a
noisy place.
Many underwater sounds have been identified
, but even more still
await classification. Fish in the public aquarium are quite well talkative.
So
scientists have been able to record their sounds and match them with mystery
calls heard from the open sea.
Alice
: So who's the noisiest in the underwater world? I'll bet it's the dolphin.
Paul
:
You're right.
The dolphin is noisy but
by far the most
widespread and
persistent are the smaller animals living in the sea. Not fish but an animal that
lives on the seafloor and grows no more than about five centimeters. Here,
have a look at this table I've started.

: Ah!
I see the snapping shrimp is the noisiest sea creature
. This is
interesting; it
makes
its
sharp
snapping sound with its
enlarged
claw which
also functions like a water pistol.
Paul
: Yes, I was reading millions of these animals just offshore have been
known to frighten people walking along the beach in Japan.
Michelle
: And this is interesting,
it says here that seahorses in an aquarium
made such a loud noise
that people could hear them from across the room
.
These little creatures are amazing.
Michelle
: Say Paul, your early research has really prompted me to get started
on my own paper. You look like you've already done quite a lot of work on it,
but the assignment isn't due for at least another month. Is that right?
