Дикие животные

Если о природе, животном и растительном мире, окружающими нас на суше и в воздухе мы знаем достаточно много, то о подводном царстве Нептуна наши знания подчас скромны и недостаточны. Отчасти сие связано с ограниченностью человеческих возможностей и трудностью освоения и враждебностью подводной среды обитания. А ведь этот мир до сих пор хранит в себе множество тайн и загадок и сулит ещё множество открытий чудных.

Огнетелки, они же пиросомы. Сознайтесь, уважаемые читатели, что Вам это название ничего не говорит и многие из Вас слышат его в первый раз. Википедия даёт довольно скудные сведения об этих подводных животных. Огнетелки- морские свободноплавающие колониальные животные. Размеры взрослых колоний от нескольких (обычно 20—30) см до 4 м и более. Колония цилиндрическая, полая, открыта на одном конце. Стенки её из стекловидно-прозрачной туники, в которой в один слой располагаются тысячи небольших одинаковых зоидов, мельчайших организмов, которые копируют сами себя и сплетаются вместе. Колония плавает замкнутым концом вперёд. Многие огнетелки имеют бактериальные светящиеся органы и способны к интенсивной люминесценции.

Пиросомы являются одними из самых редких существ на Земле. Встретить их под водой всё равно, что встретить живого единорога. А уж заснять их на камеру и вовсе удалось всего несколько раз. Даже в глубинах океана, которые буквально кишат разными невообразимыми существами, гигантские пиросомы остаются одними из самых странных.
