Rattail fish, also known as grenadiers, are deep-sea fish characterized by their long, tapering bodies that resemble a rat's tail. 🐠 They are found in oceans worldwide, typically at depths of hundreds to thousands of meters. They use their sensitive barbels (whiskers) to detect prey in the dark depths. Think of them as the stealthy predators of the abyss. Their bodies are fragile and their scales are small. They are adapted to withstand immense pressure.
