Detailed explanation-1: -Characteristics of Invertebrates In addition to not having a backbone, invertebrates have soft bodies because they don’t have an internal skeleton (endoskeleton) for support. Instead, many have structures on the outside (exoskeleton) that provide support and protection.
Detailed explanation-2: -Marine invertebrates live in coral reefs, shallow mangroves, sea caves, and deep in the ocean inside remote sea vents. Some marine invertebrates pick parasites off of fish, others remove harmful algae from coral reefs, others float through the water column, and still others are found sifting and burrowing through sand.
Detailed explanation-3: -Invertebrates do not have backbones. This is the major characteristic that separates invertebrates from vertebrates. Invertebrates have a less complex nervous system. Invertebrates are cold blooded animals. Invertebrates have distinct body parts.
Detailed explanation-4: -The majority of living animals are invertebrates. Invertebrates lack a backbone. Invertebrates may have an incomplete or a complete digestive system. Invertebrates vary in how they move and in the complexity of their nervous system. Most invertebrates reproduce sexually. 05-Mar-2021
