When crabs that have not spawned yet come to the beach
at high tide Information from local guide Kazu Yamamura.

The high tide on January 24 is 0:49 am.
Then it was 1:00 am full with enthusiasm.
I came to the beach to see the spawning
with my own eyes while rubbing my sleepy eyes.

In total darkness, I rely only on the light of the flashlight.
Only a few were found on the beach.

I'm afraid I was late to come.

Burrows are also made on the coastline and in the gardens of private houses,
and leaves are packed at the entrance of the burrows to rehydrate.

When the rainy season begins from October to November,
large movements begin from the forest to the coast
for spawning (mating and spawning / spawning).

At 2:00 am on December 27, 2005,
the beach was bright red and the situation at that time Mr.Nagata told me.

He said he was crazy about shooting the spawning
It seems that his back was a crab,
a crab, and a crab.

Males are larger than females
and females have smaller nippers.

Crabs can be found in the mountains of the Island
and in the gardens of private houses,
but rarely appear during the day when the sun rises.
 
Because they die from lack of water.

A small stream in the forest is a great habitat for the red crab.  

What surprised me was that there was also a crab (blue crab).

The most important thing about land crab is hydration.

 

The red crab that was shown on the TV program "Discover the World of Mystery!"
The spawning season of the red crab,
which is home to 70 million animals,
is from land to sea.

There is a large line.

It is said that there were 100 million animals 10 years ago,
but it is said that the number has decreased sharply due to the outbreak
of yellow crazy ants (ants) and the influence of cars and humans.

A male waiting for a female.

After breeding behavior, the male returns to the burrow in the mountains.

Females lay eggs 2-3 days after mating.

(Release the egg into the sea 12 to 13 days after incubation)
It is possible to hold 100,000 eggs
at that time I didn't know that.
