Fish Crustaceans Mammals
The seven types are protozoa, annelids, mollusks, echinoderms, crustaceans, arachnids, and insects.
Crustaceans typically possess compound eyes, which are made up of numerous small visual units called ommatidia. These eyes provide a wide field of vision and are highly effective in detecting motion and changes in light. Some crustaceans also have simple eyes, or ocelli, which can help with light perception. The combination of these eye types allows crustaceans to navigate their aquatic environments effectively.
Some things that would be considered crustaceans are things that have hard shells and live in the ocean. For example, shrimp, crabs, lobster, and mantis shrimp are all crustaceans.
Crustaceans, such as crabs, shrimp, and lobsters, are prey for a variety of animals in their ecosystems. Common predators include fish, birds, and marine mammals like seals and sea otters. They can also be consumed by other crustaceans, such as larger crabs. Additionally, some species of octopus and certain types of sea turtles are known to feed on crustaceans.
Some crustaceans are omnivores.
Crustaceans are a completely different species of Arthropod, because they have 10 legs, pupils in their eyes, etc. Most types of crustaceans also live in the water, although a few species of insects also live underwater.
