The fishes have bony spikes to support their fins and have 'swim bladders` to assist in buoyancy.

The , including the now extinct , were most abundant between 245 and 66 million years ago, and today include birds, crocodiles, snakes, and lizards. Modern-day reptiles possess hard, keratinized that protect them from and predation. Some reptiles, including snakes, possess specialized that are used as sense organs to analyze chemicals in the environment. Reptiles are , meaning that their body temperature matches the temperature of the external environment. Reptiles produce leathery shelled eggs that can withstand dry conditions on land. C. Most living mammals are mammals, meaning the extraembryonic membranes of the amniotic egg have been modified for development within the uterus of the female. The contributes to the fetal portion of the placenta, while part of the contributes to the maternal portion. These mammals have adapted to life on land and have to allow for rapid movement. They have hearts, expanded lungs, and consistent body temperatures. They have large that are not fully developed upon birth and offspring remain dependent on their parents for a time after birth.
