echinoderm etymology

Etymology:

The word "echinoderm" is derived from the Greek words:

• echinos (ἐχῖνος): meaning "hedgehog" or "spiny"
• derma (δέρμα): meaning "skin"

Meaning and Origin:

Echinoderms are marine invertebrates that have a spiny or prickly skin. The term "echinoderm" was coined by the French naturalist Jean-Baptiste Lamarck in 1801 to refer to this unique characteristic.

Echinoderms are characterized by a number of distinctive features, including:

• Radially symmetrical body with a central axis
• A hard, calcareous skeleton covered in spines
• A water vascular system used for movement and feeding
• A five-part digestive system
• A unique larva form known as a pluteus
