Sea creatures

Seahorses have always amazed people with their unusual appearance. These amazing fish are among the most ancient inhabitants of the seas and oceans. The first representatives of this fish species appeared approximately forty million years ago. They got their name from their resemblance to a knight chess piece.

One of the most ancient animal species, mysterious and little-studied, are sharks, also known as selachians. Numerous myths and legends surround this marine fauna, contributing to prejudice against these amazing fish. Systematic study of selachians began during World War II, during battles in the Pacific and Indian Oceans. The goal was to find a way to protect humans from these marine predators.

The depths of the sea and ocean conceal many mysteries and enigmas, sometimes very dangerous for humans. They are home to a wide variety of fauna, some of which are extremely large. The killer whale is one such animal. Many of us have heard the most terrifying stories about it, seen movies, and seen gripping animal television programs. What is a killer whale, what does it look like, how much does it weigh, and what does it eat?
