The same is true for sea squirts. Yes, in fish the pharyngeal pouches go on to push through to the outside of the body, and the tissues between the 'slits' develop into the gill bars of bone or cartilage that support the delicate filaments of the gils themselves.

Step 1: Understanding Plastics. There are many different kinds of plastics. Some of them are easier to repair than others. Many plastic parts are made from a plastic called ABS. It is a hard, somewhat brittle plastic and is easily broken. Small pieces with clean breaks can often be super-glued much like reattaching a handle to a tea cup. For larger pieces or for more extensive repair, hot melt adhesive can be used.
