The presence of tropical shark species in northern waters serves as a biological indicator of shifting ocean temperatures and ecosystem changes in the New England region.
Key Facts
- A juvenile tiger shark was caught and released by fishermen off the coast of Falmouth, Massachusetts, in late July.
- Tiger sharks are typically found in warmer, southern waters like the Caribbean.
- Scientists suggest the northern migration of tiger sharks is linked to rising global sea temperatures.
- Researchers are investigating whether the waters off New England are becoming a nursery for juvenile tiger sharks.
- Adult tiger sharks can grow to over 15 feet and 1,400 pounds (635 kilograms).
- Other marine species, including great white sharks and black sea bass, have also been observed moving further north in recent years.
