If the rumour is false, it is false. (The suggestion that the species in
question were unknown to science is laughable, of course.)

But is the claimed phenomenon improbable? There is a published report of
water from the depths (few hundred metres) where those species occur
being raised onto the continental shelf by the low-frequency wave
generated by a storm passing over the Great Australian Bight. [The
report was published in AJMFR circa 1986 but I would have trouble
tracking down authors and page numbers.] I don't claim to understand the
physical mechanism, though I have seen it demonstrated in a tank. It has
something to do with a wave, in passing from deep water to shallow,
creating an intense movement of water up and down the steep slope
between and very close to the seabed of the slope.

Would a tsunami have the right frequency and amplitude to have that
effect? Would the water movement be such as to carry fish along with it?
I have no idea but I'd not dismiss the possibility unless somebody with
a solid understanding of the physics said that it couldn't happen.
