I honestly have no clue what it is you guys want anymore so here, take this.

With its good sense of smell
And can swim very well
That's a moray ..... a moray ....... a moraaayyyy....

We need Ripley to kill it.

Nature is great! And also very scary

Why is there a mini monster in the big monster?

The second set of jaws are literally in their throat, it's wild, apparently they evolved from a second set of gills.

When a grid's misaligned
With another behind
That's a moiré...
When the spacing is tight
And the difference is slight
That's a moiré...
(stolen from xkcd, which was talking about the rainbow-y patterns you get when you take a photo of a screen, in the comic Color Pattern)

When the jaws open
And there's more jaws inside
That's a moray~

When an eel bites your knee
In the deep briny sea
That's a moore ray
With teeth oh so sharp
It's definitely not a carp
That's a moore ray
