They have blood that circulates through blood vessels and lungs (or gills) for breathing. Lungfish are freshwater rhipidistian vertebrates belonging to the order Dipnoi.Lungfish are best known for retaining ancestral characteristics within the Osteichthyes, including the ability to breathe air, and ancestral structures within Sarcopterygii, including the presence of lobed fins with a well-developed internal skeleton.Lungfish represent the closest living relatives of the tetrapods. Animals in the intertidal zone do not have to deal with high water pressure but need to withstand the high pressure of wind and waves. Fish (plural: fish or fishes) are an aquatic group of vertebrates which live in water and respire (get oxygen) with gills.They do not have limbs, like arms or legs, and they do have digits (fingers & toes). They are cold blooded.

Respiration is through gills or lungs. They eventually include all the sharks, skates and rays. Fish breathe through gills instead of lungs. Sharks and other more primitive fish may have five or more gill slits. D) Skates and rays exchange gases across their skin and thus require a high surface-area-to-volume ratio; sharks use gills to respire. 1. Rays and frogs have a vertebral column.

Sharks and rays typically have five pairs of gill slits that open directly to the outside of the body, though some more primitive sharks have six or seven pairs. The gills of Elasmobranchii (sharks and rays) have the same structural components as those of lampreys except that the gill skeleton lies medial to the filaments (Fig. Other Compare and Contrast books describe the first subject in its entirety and then describe the second subject. Fish Gills. Many marine invertebrates and plants in this habitat have the ability to cling onto rocks or other substrates so they are not washed away and have hard shells for protection.
