Adult female Diamondback Terrapin (Malaclemmys terrapin) at sunset in a South Carolina tidal creek. The individual in the image has been captured several times as part of a long-term capture-mark-recapture research project on Kiawah Island, SC. From Texas to Massachusetts, Diamondback Terrapins occupy brackish coastal waters where they consume mostly mollusks and crustaceans. Females are larger than males and have proportionally broader heads than do males.

Marine Iguana (Amblyrhynchus cristatus) on Floreana, Galápagos, Ecuador. With as many as seven subspecies recognized, Marine Iguanas are endemic to Galápagos and are the only lizard that routinely occupies the marine environment. Nasal salt glands aid in the excretion of electrolytes that are ingested while foraging on marine algae. Males may form leks during the mating season and typically attain much larger body size and have broader heads with larger tubercles when compared to females.

A 4.1 m male American Crocodile, Crocodylus acutus, from the Río Reventazón, Limón Province, Costa Rica. Crocodylus acutus ranges from northwestern South America, through Central America and Mexico, and northward across the Greater Antilles to Florida in the United States. As a euryhaline species, C. acutus occupies freshwater to fully marine habitats. The diverse diet of C. acutus varies ontogenetically and includes aquatic invertebrates and various vertebrates, very commonly fish.
