The answer is D. Spider.
Tortoises, snails, and turtles are all members of the reptile family Testudines. They are all characterized by a hard shell that protects their soft bodies. Spiders, on the other hand, are arachnids, which means they have eight legs and two body segments. They are not closely related to reptiles.
Tortoises are typically larger than snails and turtles. They have a thick, domed shell that protects their entire body. Snails have a soft body that is protected by a spiral shell. Turtles have a hard shell that protects their back and sides, but their belly is exposed.
Tortoises, snails, and turtles are all ectotherms, which means they cannot regulate their own body temperature. They must rely on the environment to warm up or cool down. Spiders, on the other hand, are endotherms, which means they can generate their own heat.
Tortoises, snails, and turtles are all herbivores. They eat plants, fruits, and vegetables. Spiders are carnivores. They eat insects, other spiders, and small mammals.
Tortoises, snails, and turtles are all found on land. Spiders can be found on land or in water.
Tortoises, snails, and turtles lay eggs. Spiders lay eggs in silken sacs.
Tortoises, snails, and turtles are all slow-moving animals. Spiders are fast-moving animals.
Tortoises, snails, and turtles are all considered to be beneficial animals. They help to control populations of insects and other pests. Spiders are also considered to be beneficial animals, as they help to control populations of insects. However, some spiders are venomous and can be dangerous to humans.
