Japanese Sicyopterus

Postby odyssey » Sat Jan 26, 2013 11:50 pm

Hi everyone!
I add images of two kinds of Sicyopterus inhabiting Japan after a long absence.

These are Sicyoputerus japonicus taken in the middle portion of the Izu Peninsula of Japan in the fall of last year.
Image
Image
Image

On the other hand,these are Sicyoputerus lagocephalus that live in the most southern part of Okinawa Japan.
Image
Image
Image

Because the characteristic of the species does not yet appear in the fries, the distinction with S.japonicus is difficult.
However, it is more likely to be S.lagocephalus when I think about a season.

Sicyopterus japonicus and lagocephalus

Postby odyssey » Thu Jan 31, 2013 10:42 am

Hi plaalye!

I can distinguish S.japonicus from S.lagocephalus easily.
S.japonicus has a lateral stripe design without disappearing since the age of a child fish.
The design is a pattern such as "\\\\\\\ //////".
S.japonicus does not seem to change most of the designs of the body, but S.lagocephalus can change a color of the body busily.

The following photo is childish fish of S.japonicus which just went up from the sea to the river.
Image

This is a 2-year change of the same S.japonicus individual.
Image

The next picture is a figure three years before and the recent figure, same individual of S.lagocephalus .
S.lagocephalus can completely delete the pattern of the body.
Image

S.japonicus and S.lagocephalus.
Image
Image

S.lagocephalus and Sicyopterus.sp(Mountain Rock Goby)
Image

Though S.lagocephalus change the pattern of the body, a specific pattern appears.
The scientific name "lagocephalus" seems to mean the head of the rabbit in Greek.
May you find the white pattern like "a head of rabbit" in the tip of nose of S.lagocephalus?
Or the big white pectoral may be likened to the ear of the rabbit.

Great description odyssey, thanks! Except for the "rabbit head", mountain rock goby and s. lagocephalus look very similar.

Sicyopterus japonicus

Postby odyssey » Sun Nov 03, 2013 11:53 am

Hi everyone!

I visited some rivers of Izu Peninsula last month and took many photos of underwater.
I want to see waterfall-climbing scene of Sicyopterus japonicus and visit the river of Izu Peninsula for five years, but it was only once that I was able to watch it.

Sicyopterus japonicus in Izu Peninsula of October, 2013.
A video clip is in youtube.

Image
Image
Image
Image
Image
Image
Because they eat an adhesion alga, both S.japonicus and sweetfishs do a territorial dispute each other.

Sicyopterus japonicus in Kii Peninsula of June, 2012.

Waterfall-climbing scene of Sicyopterus japonicus in Izu Peninsula in 2009.
Unfortunately it was only this time that I was able to watch their waterfall-climbing.
In this district, this age had little rain in particular.
Possibly their waterfall-climbing action may be related to a lack of rain.

I edited a former video briefly and uploaded it newly this time.

Hi everyone!

I did the expedition travel to a Ryukyu area that was the subtropics climate in the south end of Japan last December.
Unfortunately there are few pictures of Sicyopterus genus.

Hi everyone!

I traveled to Amami-ohshima that was a southern island of Japan last month.
And I took lot of pictures of Sicyopterus japonicus there.

The youtube video that fries go up in a river from the sea
https://youtu.be/yZI-o_sqba4

The fry which just switched over from seawater to fresh water.
Image
Image
Image

The fries go up in crowds to the upper reaches.
Image
Image
Image
Image
Image
Image

The individuals which grew up drift the bottom and graze algae.

wasserscheu stated that it was like Sicyopterus cynocephalus in this thread before.
I think so, too.
This Sicyopterus rarely arrives at the aqua shop as from Indonesia.

Your Sicyopterus.sp seems to be neither S.japonicus nor S.lagocephalus.
I think that's probably the same species as "Moutain Rock Goby".

You can display images directly if you sandwich the "URL" of the image in "[img]"and"[/img] "
For example as follows

Hi sj861008!
I have not seen such change in Sicyopterus.
Very interesting.

About direct indication of picture.
It doesn't seem often able to indicate a picture of your site directly.
I'll apologize for having told the wrong means.
It's sometimes made indication directly, but it isn't almost indicated.
