No,
they are crustaceans, not fish .
they are invertabrates.
all but crayfish and frog are vertebrates
A Crayfish is a crustacean, which do not have backbones.
Both goldfish and lizards are coldblooded vertebrates with tails that lay eggs.
In crayfish, arteries function to transport oxygenated blood from the heart to various tissues and organs throughout the body. Unlike the closed circulatory system found in vertebrates, crayfish have an open circulatory system, where the blood (hemolymph) is pumped into spaces surrounding the organs. This allows for the exchange of nutrients and waste products. Overall, arteries play a crucial role in maintaining the flow of hemolymph, supporting the crayfish's metabolic processes.
Well, honey, a crayfish is a non-vertebrate animal. It falls under the lovely category of invertebrates because it doesn't have a backbone to strut its stuff. So, next time you see a crayfish, just remember it's all squishy and spineless, just like your ex.
No. Apart from the fact that there are no minks in Australia, the platypus generally does not feed on other vertebrates. It only feeds on invertebrates such as annelid worms, crayfish and insect larvae.
Birds and mice are vertebrates, they have warm bodies, hearts, muscles, lungs, eyes (two each), 4 limbs, digestive systems (some like the same foods)...
Crayfish
Raccoons eat a diet of fruits, vegetables, and acorns. However, earthworms, fish, and other marine and fresh water animals (such as crayfish) are also on the menu from time to time.
Animals without back bones are called Invertebrates.
Crayfish are known as both crayfish and yabbies in Australia. "Yabbies" are freshwater crayfish, often found in rivers, creeks and dams in rural areas.
