滝の拝 Takinohai
(日本語)
この穴だらけの奇妙な岩は「滝の拝」と呼ばれています。この岩は約 1800万年前に海底に堆積した砂と泥からできています。これらの無数 の穴は「ポットホール」と呼ばれ、水流で川底の石が回転して河床に穴 を開けたものです。
(このような穴ができるには岩が十分硬くなることが必要ですが、およそ1400万年前に発生したマグマの活動がその熱源だ といわれています。)
夏にはハゼの一種のボウズハゼが餌を求めて、この滝を登るのが見られます。吸盤が発達しているためです。（ボウズハゼの映像を見せる）
This strange rock full of holes is called "takinohai". This rock is made up of sand and mud deposited on the seafloor about 18 million years ago. These myriad holes are called "potholes" and are the rotation of stones at the bottom of the river that make holes in the riverbed.
(The rock needs to be hard enough to make such a hole, but the magma activity that occurred about 14 million years ago is said to be the heat source.)
In the summer, a kind of goby, Sicyopterus japonicus, can be seen climbing this waterfall in search of food. This is because the suckers are well developed. (Show the image of ボウズハゼ)
