Wishing everyone a happy and healthy Christmas from the My Biology Experience family!!
Crabs fall into the category of crustaceans. These creatures of the deep can range in sizes from the tip of your finger to the size of your body! Feared and enjoyed by so many, these animals have adapted extremely well for their environment.
Crustaceans have a hard exoskeleton. This skeleton is made of the same material in your finger nails called chitin. Hidden in their thorax is actually a tail! This tail was thought to shorten over hundreds of years of evolution. Within their stomach crabs have teeth that crush their food into a pulp for digestion.
So if you are every enjoying a crab, admire their evolutionary features that have made them such a diverse species in the deep around the world.
Plants are one of the most diverse organisms on this plant. One of the major classification of plants is if it is vascular or nonvascular. Non vascular plants usual consists of things like mosses. They are low to the ground and absorb water directly through their surface.
Vascular plants are the tall leaf structure plants with the almost vein looking structures in them. These structure are called xylem and phloem. They are responsible for the transport of water and nutrients throughout the organism.
