In the Pacific Ocean which spreads off Kochi, there is the grand Balaenoptera brydei. In Kochi prefecture famous for whale watching a whale is sightseeing material. While there are several kinds of whales, Balaenoptera brydei is a kind currently liked by many tourists.This Balaenoptera brydei is introduced this time.
Description & Taxonomy
It is distinguished in outside because mustached hair is baleen is short and that apply near a nostril from rostrum edge and the right-and-left both sides of the upper surface of a snout have an upheaval line of one articles each although it is close species of a sei whale, that a trough is long and the tip has reached the navel, wide, and thick.
The length is also slightly smaller than a sei whale, and is only a maximum of 15.5 meters.
Although Balaenoptera brydei was presupposed that only the South Africa coast is inhabited once, it was discovered around the postwar years and Ogasawara Islands, and it became clear that it was also widely distributed over the North Pacific.
We decided that the International Whaling Commission will correct the appended chart of Convention for the Regulation of Whaling in 1970, and it treats this kind and a sei whale as another kind. The small fish which this kind uses as the staple food is the food of large-sized wide-ranging fish, such as a bonito, and a possibility that the group of large-sized wide-ranging fish is in the ocean space in which this kind is present also becomes high.
Moreover, there is a merit which protects itself from swordfish by being attached to a whale in a bonito, and katsuokujira of this kind or a close relationship forms one small ecosystem by one individual.
Use & Conservation
Balaenoptera brydei becomes known as the subject of whale watching, and is loved, and the whale is enjoyed as what is not eaten and is seen now when control of whaling is severe.
In the Fisheries Agency version Red Data Book, it is regarded as the rare animal and has become a candidate for preservation.

Myrica rubra is called yamamomo. It is a subtropical tree grown for its sweet, crimson to dark purple-red, edible fruit. Its fruit is a sweet-sour delicious. The Japanese name suggests the word peach, but Yamamomo and peach are totally different plant. Yamamoto is a Prefectural flower of Kochi.
Description and Taxonomy
Yamamomo can grow to a height of 10～20 meters. The leaf is 10 cm,dark green with cortex. It is dioecious, with separate male and female plants. The root system is 5～60 cm deep, with no obvious taproot. The fruit is spherical, 1.5～2 cm in diameter , with a knobby surface. The surface color is typically a deep red, red , it seemed to display small red beads. It matures in July from June. The flesh is sweet and very tart. At the center of the flesh is a big signal seed.
It called Morella rubra Loureiro; Myrica rubra var. acuminata Nakai. It is usually cited as Myrica rubra. Yamamomo is a small family of about 30 types. For a long time it was said that family was separated by three genus, and many kinds were classified in the Myrica genus, and Yamamomo was included.
Range and Ecology
Yamamomo is native to eastern Asia, Japan, China. It grows in the warm place and is strong in heat. In Japan, it grows wild in lowland and the mountainous district from Kanto and to the south in Japan. In the south in southern Honshu, it is an important tree class constituting the forest in unproductive land such as the shore or the dry ridge of the low mountain. . It tolerates poor acidic soils, because it lives together with bacteria called franckia performing nitrogen fixation.Therefore it may be used for tree planting.
The fruit of the Yamamomo is eaten fresh and is processed into jam and wine. There are two main types of Yamamomo, a sour type used for making dried fruit and a sweet type used for juice and fresh eating. So the bark include a lot of tannin, it may be used as medical use. It might be planted a tree in the fields and moutains. Nowadays it is planted in a park and the street as a roadside tree. How to propagate is by grafting and layering.
The main producing center is Tokushima and Kochi in Japan. The seasonal time of Yamamomo is a short period of less than one mouth. So it may be said that Yamamoto is a precious fruit letting you feel the season. If you would like to eat Yamamomo, go to Kochi (or Tokushima!) in the rainy season.

Description & taxonomy
Its average size is from 20 to 25mm. It is called `scorpion` because of its appearance. Japanese name is Sasorimodoki. But it is close to spider. It lives in tropical area and subtropical area. Vinegaroon has about 100 species. It has two spiecies in Japan. There are Typopeltis stimpsonii in Kyusyu, Typopeltis crucifer is on Yaeyama island. Kochi`s Vinegaroon is thought to be Typopeltis stimpsonii. It`s a range spreads every year and it live in Kobe and Ogasawara island now. We can recognize it by scissors form. Kochi`s vinegaroon is thought that be brought by people.
Range & ecology
It lives under stones and prefer humidity. It`s staple food is insect, a cricket or a grasshopper. It is cannibalistic. It catches insect by using scissors. In winter, it hibernates. It has poison that smell vinegar. `Vinegaroon` cause this poison. If people touch this poison, causes Dermatitis and maybe loss of eyesight. If you touch vinegaroon, you must wash your skin.
Use & conservation
It is specified Endangered species in Kochi. In Kumamoto prefecture, it is specified Natural treasure. It is thought that its numbers are decreasing because it is carniverous and the number of cockroach or cricket which it feeds on is also decreasing.

In 1935, an insect like small beans of about 3cm was discovered by Mr. Sasaki, a teacher of Ali junior high school. It is called Cissites cephalotas. The common Japanese name is Hirazugensei. It means Gensei of flat head. But this insect was discovered in Kochi at first, so often it is called Tosahirazugensei and is the Prefectural Representative Insect of Kochi.
Length is about 3 cm. Color of the body is vivid red, six legs and big jaw is black. Male jaw is large and powerful looking, but female jaw is small.
As mentioned above, at 1935 it was first observed in Kochi. Later Dr.Kawano who was professor in Hokkaido university, named the male Sasakihirazugensei, named the female Tosahirazugensei. In other words, he thought that the different sexes were two different species. But at present these two species are one species, this fact is established. Also later there are records in Inoguchi, Kawakita, Ibiki etc. in Aki city.
This is included of family Meloidae. In this family there are more 10 species for example Kirogensei etc･･･. It is certain thing which the rare insect is collected in Aki city. So this insect is a souvenir insect as Kochi.
Hirazugensei live in Honsyu,Shikoku,Kyusyu district of japan, the Philippines, Taiwan, Vietnam, Myanmar, Malaysia and Indonesia, and it is found in forest mountain (low~middle level) etc. Especially, this insect lives around nests (beats) on the plains.
It is known that Hrazugensei has a relationship with a certain beetle (Kumabachi). Larva of Hirazugensei grows in nest of Kumabachi. Adult comes out from nets of Kumabachia from June to July. But it is unknown how the larva invades the nests, or what food the larva eat to grow. Therefore the appearance in nests is not known. There are unknown points about Hiratagensei. The cause of this is that Hiratagensei is rare insect. (Appointed associate endangered species in Kochi) But a lover of insects in Kochi wish that they understand myself about ecology of Hiratagensei which is recorded at first in Kochi.
Hirazugensei live around the nests of animals in the plains. So searcher should search nest of Kumabachi (it could be found in temples, old house, a house made of wood) at first, next look nests below.
Many Japanese children enjoy collecting insects. However, as they get older, people often lose interest in insects. This interesting discovery can make people interested again at any age. If you are lucky, you can find HIrazugensei.Lets come back to curiosity.
