Is a turtle an aquatic invertebrate?
Yes, a turtle is an aquatic invertebrate. A turtle’s body is composed of a hard shell and a water-repelling skeleton.
Their limbs are adapted for swimming and they have a flattened snout and round eyes. They are able to breathe under water and their scales give them a smooth, glossy appearance.
Is a sea turtle a vertebrate or invertebrate?
Sea turtles are reptiles and are therefore vertebrates.
What is a sea turtle?

Some sea turtles can swim very fast and can travel long distances.
Are turtles reptiles?
Turtles are reptiles that are classified in the orders Testudines and Cheloniiformes. They are amniotes, which means that they have a vomeronasal organ, which is used to detect chemical cues in the environment.
Turtles are ectothermic animals and have a thick carapace that helps protect them from the elements. They are oviparous, which means that they lay eggs.
Are turtles amphibians?
Turtles are classified as reptiles, meaning that they are descendants of a group of animals that first evolved on land. However, many turtles still spend a large portion of their lives in water, and they are considered amphibians, meaning they have characteristics of both land animals and water creatures.
This includes the ability to breathe both air and water, and the ability to change their body shape to fit their environment.

Turtles are ectotherms—their internal temperature varies according to the ambient environment, commonly called cold-blooded. However, some species exhibit temperature sex determination.
Yes, a turtle is an invertebrate because it lacks a backbone.
