Well bones in an embryo aren't really there yet until the embryo becomes multi cellular and more of a child. Even when the embryo becomes more complex the bones are still just cartilage the same material that makes up your nose. Over time a bone cell called osteoblast applies both calcium and phosphate thus the bones become more dense
hope i answered your question
Um, I think it is...Cartilage?
In an embryo, the skeleton is originally made of cartilage. This cartilage gradually mineralizes and ossifies into bone in a process called endochondral ossification.
The skeleton of an embryo is originally made of cartilage, a flexible tissue that later undergoes ossification to become bone. During development, the cartilage is replaced by bone in a process known as endochondral ossification.
The major bones of the axial skeleton include the skull, the vertebral column, the ribcage, and the sternum.
A newborn baby's skeleton is primarily made of cartilage, which gradually hardens into bone over time as the baby grows. This process, known as ossification, enables the baby's skeleton to become stronger and more durable as they develop.

the ability to move the cartilage and squeeze his/her way out of there!!

A hydraulic skeleton is composed of muscle and fluid.
