鳥吉英伸 Hidenobu Toriyoshi 医学博士】「深海の輝き：生物発光の不思議な世界 🌊✨ クリックして探索しよう！」 深海では発光する生物が多い。【獣医師の雑学】#動物 #shorts #生物 Dr. Hidenobu Toriyoshi 鳥吉英伸
生物が発光する現象を「生物発光」と言います。生物発光を示す生物には多くの種類があり、クラゲ、イカ、ホタルなど陸上の生物でも知られています。多くの海の生物がこの特異な能力を持ち、特に深海の環境では微生物や魚が特に発達した形態でこの現象を示します。
深海生物が生物発光を活用する理由は、深い海底の環境が通常の太陽光による照明を受けにくいためです。
深海は非常に暗い環境であり、太陽光が海水に浸透する深さは限られています。光は水に吸収され、深海にはほとんど届きません。このため、深海の生物は他の手段で自分たちの周囲を照らし、情報を得る必要があります。
生物発光は、深海生物にとって捕食と防御の両方に役立ちます。捕食者は光を発する獲物を見つけやすくなり、また獲物も仲間を呼ぶことで大群になりやすいです。一方で、一部の深海生物は光を放って敵を欺き防御します。
深海生物は同種や仲間とのコミュニケーションにも生物発光を利用します。例えば、交尾の際や仲間同士の位置を知らせるために光を使います。これは深い海の闇の中で仲間を見つける手段となります。
深海生物の生物発光は、通常の可視光だけでなく、紫外線や赤外線などの広い範囲の波長で発光することがあります。これにより、他の生物が見ることのできない領域でも情報の交換が可能です。
生物発光は深海生物にとって非常に特異かつ重要な適応戦略であり、深い海の中での生態系の一環として理解されています。

In the deep sea, bioluminescent organisms
are abundant.
The phenomenon of organisms emitting light
is called "bioluminescence." There are various types of organisms
that exhibit bioluminescence, including jellyfish, squid, and fireflies, which
are also known in terrestrial environments. Many marine organisms possess this
unique ability, and in the particular conditions of the deep sea,
microorganisms and fish especially display highly developed forms of this
phenomenon.
The reason deep-sea organisms utilize
bioluminescence is due to the challenging environment of the deep ocean floor,
where normal illumination from sunlight is limited.
The deep sea is an extremely dark
environment, and the penetration of sunlight into the seawater is restricted to
shallow depths. Light is absorbed by water, and as a result, very little
reaches the deep sea. Therefore, deep-sea organisms need alternative means to
illuminate their surroundings and acquire information.
Bioluminescence serves both predation and
defense purposes for deep-sea organisms. Predators can easily spot prey
emitting light, and the prey, in turn, can attract others by producing light,
forming large groups. On the other hand, some deep-sea organisms use light to
deceive and defend against predators.
Deep-sea organisms also employ
bioluminescence for communication among individuals of the same species or
group. For example, they use light during mating or to signal their positions
to each other. This becomes a crucial means for finding companions in the
darkness of the deep sea.
The bioluminescence of deep-sea organisms
may occur not only in the visible light spectrum but also in a wide range of
wavelengths, including ultraviolet and infrared. This enables the exchange of
information in areas where other organisms cannot see.
Bioluminescence is a highly unique and
essential adaptation strategy for deep-sea organisms, contributing to the
overall ecosystem in the depths of the ocean.
