This species found in our bays is seen most frequently at passes to the Gulf. Texas dolphins are organized into sub-populations occupying specific areas of the coast. They feed on a wide variety of fish and mollusks, though mullet constitutes a large part of their diet in Texas bays. Through echolocation, they find food, using groans, whistles and barks. Their gestation period is about 12 months and a single calf is born every second or third year.
Dolphins show remarkable instances of cooperation.
To aid an injured individual, dolphins may support the hurt animal at the surface. A great place to observe these creatures is at ferry crossings. Keep your eyes out for their characteristic dorsal fin and pay close attention to characteristics of individuals, such as unusual scars on the fin or unusual coloration. You might be able to identify the same individual on subsequent trips to your favorite viewing spot. Six other marine mammals occur with sufficient frequency to be seen occasionally.
