Develop a hypothesis to explain why you think eurypterids developed legs even though they lived on the ocean floor.
expeople1 [14]

I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor. Their movements mostly on the ocean floor. So fin would not help them "stick" to the floor. Also there are still gravity acts on the Eurypterids and the feet would help them move faster. Hope this helps.

Sloan [31]

A human fetus develops at the mother’s body temperature. At birth, most newborns experience a drop in temperature, and their bodies must quickly do something about it. What they do is the same thing a hibernating mammal does as it rouses itself from its winter "snooze." During hibernation, an animal’s body temperature is low. In order to move about and take care of itself once awake again, the animal that has been hibernating must raise its body temperature. (William k. Purves et al., life: the science of biology) The definition is the primary pattern of organization in this passage.

This passage is explaining the process of hibernation and its importance in the animal life cycle.
