Most of the Arctic consists of sea ice and not land. Much of the land that is found in the region is tundra coverd with permafrost. Only a few inches of this permafrost thaws during the short summer months. The desert, especially the hot desert, has a greater variety of plants and animals, does not have permafrost (except Antarctica) and all deserts are located on solid ground, not sea ice.
There are whales, seals, dolphins, and many more animals in the sea.
A Sea Turtle
Because there are many, many dangerous animals.
Skin provides a protective covering for the body, guarding against physical harm and pathogens. Bark serves as a protective covering for the trunks and branches of trees, helping to prevent damage from insects, animals, and environmental elements. Turtle shells act as a protective covering for these reptiles, offering defense against predators and external injuries.
Seashells are created by sea animals called mollusks as part of their protective outer covering. As these animals die, their shells wash up on shore and accumulate to create seashell collections. Ocean currents and waves also play a role in moving and depositing the shells on beaches.
There really are no actual sea serpents, but there are sea snakes. Some animals that eat sea snakes include eels, sharks, and many large fish.
Sea Turtles are covered and protected by shells, similar to every other species of Turtle.
