Their skin is grey or brownish grey in color with white spots along their body and wide ridges along the length of their back.

They have very small eyes that are located at the sides of their heads and two very small dorsal fins near the back of their bodies.

The mouth of a whale shark can be found on its underside which can measure over 4 feet wide when opened fully.

2. Whale Shark Behavior Characteristics

A. Whale Shark Diet

Despite their size, whale sharks feed on some of the smallest organisms in the ocean, such as plankton and krill. They also consume many other kinds of marine life including small schooling fishes, squid, crabs, and shrimp.

Whale sharks have adapted a filter-feeding lifestyle to survive on their tiny prey items. Using their huge mouths and gills, they suck in large amounts of water that is then expelled through the gills along with any food particles caught by mucous membranes lining the mouth and gill arches.

The combination of size and specialized feeding technique allows whale sharks to consume over 46 pounds (21 kg) of plankton per day!

B. Whale Shark Habitat

Whale sharks can be found in tropical and warm-temperate waters all over the world, with some species even residing in cold waters. Whale sharks prefer habitats that allow them to easily search for food sources such as plankton or small fish, which they feed on using their wide mouths.

Whale shark presence has been documented in the Atlantic Ocean, Pacific Ocean, Indian Ocean, and Red Sea.

The whale shark is known to inhabit ocean depths ranging from shallow coral reefs up to 2,600 feet below sea level; however, the most common habitat for these majestic animals is generally coastal areas with sandy bottoms with depths reaching 164 feet (50 meters).

Additionally, whale sharks have been observed venturing into estuaries near river mouths due to abundant food sources there.

C. Whale Shark Mating Behavior

Whale sharks are one of the ocean’s most impressive creatures, and their mating behavior is equally fascinating. Although little is known about whale shark mating habits, recent studies have shed some light on this mysterious process.

Whale Shark Behavior-AnimalBehaviorCorner

Whale sharks typically travel alone and only gather in large numbers to mate during the spring. During this time, males appear to compete for the attention of female sharks by swimming around them in spiral formations.

It’s also believed that male sharks use a combination of color patterns as well as acoustic signals to attract mates.

Once a successful pairing is made, the female lays her eggs inside a special pouch on her underside before they are fertilized by sperm from the male shark in what is known as “internal fertilization”.

These gentle giants are ovoviviparous, meaning that embryos develop inside eggs within the mother’s body and are then born alive when ready.

It was reported that female whale sharks give birth to up to 300 pups after a gestation period that lasts anywhere from 10 to 18 months depending on water temperatures and other environmental factors.

D. Whale Shark Social Behavior

The whale shark is a solitary animal, however, during the mating season, these animals come together in groups to mate. Whale sharks can often be seen in large groups or “aggregations” that contain anywhere from 10-50 individuals.

These aggregations are often comprised of both males and females across multiple age ranges that have traveled from remote areas far away from each other.

It is also suspected that whale sharks communicate with each other using a variety of sounds and body movements such as head shaking and fin slapping to alert other members of the group about potential threats or food sources.

3. Whale Shark Behavior Adaptations

The whale shark, the largest fish in the world, is a remarkable species that has adapted to its environment over millions of years. This majestic creature uses various behavioral adaptations to survive and thrive in its ocean home.
