5 things you should know about bull sharks

Diving in Costa Rica with bull sharks is an immersive learning experience. If you have the opportunity to see and appreciate these impressively smart and graceful creatures, here are some things you should know about them and why they’re such a treat to see.

#1 Their size

Bull sharks can grow from 4 to 11 feet (3.5 m) and weigh up to 700 lbs (315 kg).

#2 Adaptability

Bull sharks can remarkably thrive in salt and freshwater environments thanks to a special physiological adaptation known as osmoregulation. This allows them to adjust their internal salt levels to match their environment. As a result, they can travel far up rivers and even live in lakes, a trait that sets them apart from other sharks.

#3 Varied diet

Bull sharks are not picky eaters. They eat fish, birds, small manta rays, and even smaller sharks. This dietary flexibility is another reason they can adapt to different environments, from the open sea to river waters.

#4 Importance in the ecosystem.

Despite their fearsome reputation, bull sharks play a crucial role in maintaining the crucial balance of the marine food web, according to the International Fund for Animal Welfare. Their presence in different habitats, such as reefs and estuaries, indicates a healthy ecosystem.

#5 Social behavior

Bull sharks are mostly solitary creatures, but they form groups, especially in areas with abundant food sources. This group behavior, known as a shiver, can be seen during certain activities like hunting or mating seasons.

How Do You Get to Bat Island, Costa Rica?

To reach the Bat Islands, we take a boat ride about 30 miles offshore from Playas del Coco. Once we arrive, we don’t anchor the boat, so divers need to do their safety stop without lines. 

During the dive trip, you can witness diverse marine life, including turtles, whales, and rays. The dive typically reaches 60-70 feet deep, where we wait to see bull sharks. 

The vast expertise of Bill Beard's Costa Rica sets them apart from other dive shops in the area.

What to Expect from Your Scuba Diving Adventure

  • Water temperatures range from 70-80 degrees year-round, with visibility varying from 30 to 100 feet, influenced by tides and unpredictable currents. This is why, sometimes, visibility can fluctuate dramatically due to strong currents.
  • Most divers often encounter large schools of fish like snappers and eagle rays, and it’s common to see mantas or sailfish during safety stops.
  • The main draw of this dive site is the bull sharks, especially at “The Big Scare” dive site. Despite its name, the site is safe for diving, with the island’s currents adding excitement. You’ll also see manta rays, marlin, and various fish species, making it a thrilling experience.

Discover Some Unique Dive Sites to Explore at the Bat Islands!

While the excitement of encountering bull sharks is undeniable, your adventure beneath the waves offers so much more. Here’s a glimpse into the extraordinary dive sites waiting for you:

#1 Surface interval at the Ranger Station:

The trip’s highlight is the surface interval at the ranger station within the refuge. Calm, clear waters surround this singular building on the islands. As the boat slows upon entering, watch for large wahoos resembling logs. This area is excellent for snorkeling, and you might even spot Pacific giant mantas near the entrance.

#2 Black Rock:

Often, the second dive, Black Rock, is an impressive pinnacle a mile offshore of Santa Rosa’s mainland. This volcanic rock formation is like an underwater iceberg rising from 110 feet to just above high tide. Divers descend quickly to 25-30 feet, regrouping before exploring. 

The site is teeming with schools of fish, engulfing divers in a spectacular display. A full 360-degree tour around the pinnacle offers endless marine encounters. Swimming into the open water during the safety stop can reveal different species if conditions allow.
