It sounds like you might be describing a coconut. Coconuts grow on palm trees and have a hard, spherical outer shell with a hairy appearance that can resemble a sea urchin. Inside the shell is the edible white coconut meat and coconut water.
The actual seashell is not living, it is a hard, protective outer layer made by an animal that lives in the sea. The shell is not part of the body and was never living. The common seashell is produced by a mollusc, and by the time the shell reaches the shore, the invertebrate has been eaten or rotted out, leaving the more durable exoskeleton - the seashell.
its called a cuticle, and helps the plant from losing too much water through a process called transpiration. this is the plant's way of getting water. plants with limited access to water have a thick layer to stop water from evaporating too much
Sea shells can be millions of years old, with factors like the type of shell, the environment it's in, and the conditions of preservation contributing to their age.
Members of the class Aplacophora are mollusks that have an internal plate instead of a shell. Aplacophorans lack a protective shell but possess calcareous spicules or scales in their skin. These marine mollusks are often found in deep sea environments.
As the mollusks grows the shell around it grows to accommodate the larger size. There are three layers to a shell, a proteinaceous periosteum, a prismatic layer, and an inner pearly layer.
