I went to diving for searching tiny nudibranchs today.
At first dive, the guest wanna see tiny Pikachu nudibranch, so I went to the dive point which can see it.

The color seems like Pokemon Pikachu. So we call it “Pikachu”.
The size is 2mm. It’s so tiny!!!
There are many Pikachu recently. If you wanna see it, you can see easily in this season.
At second dives, I saw these tiny nudibranchs.

These size is also 2mm~3mm.
In witer season, Some Japanese diver like searching for tiny underwatar creatures.
Of course, there are various of underwater creatures expected nudibranchs.
If you like see macro creatures, I recommend you to dive in this season.

And if you like Nudibranch, Now is the best season to see them.
Japanese sea has 4 seasons, so you can see different situation every season.
Please come and see the expressions of the sea in each of the four seasons.
See you then(^^)/











きれいな柄ですよね~!!

ちなみに、ヒロウミウシと、ミナミヒロウミウシ&アカイバラウミウシの大きな違いは、背側突起のグラデーションの向きです。根元が赤く、先っちょが白いヒロウミウシに対し、後者2種類のウミウシは、突起の根元が白く、先っちょが赤いんです!!よ~く見ると分かるけど、水中でパッと見分けろと言われると、ちょっと難しいですよね!








1匹が、ヒューっと逃げていく時に、なんと、水底で休憩してた子を、わざわざ起こして行きました!まるで「おい!!寝てたら危ないぞ!!人間来たで!!」と言わんばかりでした。
