About the only way a whale can knit is to knit two broken bone ends together. This is the normal healing process of a fractured bone. Whales do not have the manual dexterity to knit in terms of forming stretchy stitches out of loops of yarn.
It's 58% polyester and 40% rayon, and is a knit fabric that has some spandex to make it stretchy.

Materials (i assume you mean clothes of fabrics) are stretchy due to the amount of elastic in the fabric. More elastic means stretchier fabric, less elastic means it will not be as stretchy.
To achieve a professional finish on your 2x2 rib project using Jeny's stretchy bind-off technique, follow these steps: 1. Knit the first two stitches in pattern. 2. Knit the next stitch, then pass the first stitch over the second stitch. 3. Knit the next stitch, then pass the previous stitch over. Repeat from until all stitches are bound off. This technique creates a stretchy edge that complements the ribbing pattern for a polished look.
To achieve Jeny's surprisingly stretchy bind off ribbing for your knitting project, follow these steps: Use a larger needle size than what you used for the main body of your project. Knit the first stitch, then yarn over, knit the next two stitches together. Repeat step 2 until all stitches are bound off. This technique creates a stretchy edge that is perfect for ribbing.
Acrylic is not inherently a stretchy material; it is a type of plastic that is rigid and has a glass-like quality. However, when blended with other fibers, such as spandex, it can be made to have some degree of stretch. In its pure form, acrylic does not have the elasticity characteristic of stretchy fabrics like spandex or elastane.
A stretchy material is a fabric that can be stretched or expanded without losing its shape. Materials like spandex, elastane, and Lycra are commonly used to add stretchiness to clothing items such as activewear, leggings, and swimwear.
