BeauDeep sea fish evolved without scales as a way to adapt to the extreme pressure and darkness of the deep sea environment. Scales are not necessary for protection from predators or to regulate buoyancy in the deep sea. Instead, these fish may have developed other adaptations such as a gelatinous skin or spines for camouflage and defense.

What are the predators of a rattail fish?
Predators of rattail fish include sharks, deep-sea fish such as grenadiers and hake, and marine mammals like dolphins and seals. These predators hunt rattail fish for food in their deep-sea habitats.
Do all fish have scales?
No, not all fish have scales. Some fish, like catfish and eels, have smooth skin without scales. Fish scales are considered a key characteristic of bony fish, but not all fish have them.
What kind of body covering do fish have?
Most fish are covered in scales for protection. They vary in size, shape and structure and can range from strong and rigid to small or absent. The main types of scales include the cycloid scales, the ctenoid scales, the placoid scales and the ganoid scales.
How do fish survive in the ocean?
Fish survive in the ocean by having adaptations such as gills to extract oxygen from water, streamlined body shapes for efficient swimming, and swim bladders to control buoyancy. They also have specialized senses to navigate and detect prey or predators, and some species have protective coloration or camouflage to avoid detection. Overall, their evolutionary adaptations allow them to thrive in the diverse and challenging underwater environment of the ocean.
What is a fishes' body covering?
The body covering for a fish is called its scales. Scales on fish vary by size, color, number, and shape by species.
