1. What Is Blacktip Shark Food?
Blacktip shark food mainly comprises teleosts, crustaceans, and mollusks. Teleosts make up the dominant prey group, with Atlantic Croaker and Gulf Menhaden being the most important identified species. Crustaceans and mollusks form a minor part of their diet.
The diet of the blacktip shark (Carcharhinus limbatus) is varied, depending on their age and habitat. According to a study published in the journal Gulf and Caribbean Research, the stomach contents of 90 blacktip sharks in the northwestern Gulf of Mexico were examined. The study revealed that teleosts (bony fishes) were the dominant prey group, accounting for 98.95% of their diet.
1.1 What Specific Types of Fish Do Blacktip Sharks Eat?
Blacktip sharks eat a variety of fish. Of the identified teleost species, Atlantic Croaker (Micropogonias undulatus) and Gulf Menhaden (Brevoortia patronus) were the most significant.
1.2 Do Blacktip Sharks Eat Crustaceans and Mollusks?
Yes, blacktip sharks consume crustaceans and mollusks. While these form a minor part of their diet, they still contribute to their overall nutrition. The study mentioned above found that crustaceans accounted for 0.65% and mollusks for 0.46% of the blacktip shark’s diet.
1.3 Do Blacktip Sharks Eat Other Sharks or Rays?
Occasionally, blacktip sharks consume elasmobranchs (sharks and rays), but this is a very minor component of their diet. The study in the Gulf and Caribbean Research indicated that elasmobranchs constituted only 0.03% of their food intake.
