Scientists from the University of Hawaii have identified the elusive cookiecutter shark as the predator responsible for the circular wounds on marine mammals and fish, using a decade of data to analyze its behavior, feeding patterns, and environmental influences, revealing its nocturnal, stealthy hunting tactics and traditional Polynesian knowledge supporting scientific findings.
Scientists in Hawai'i have found that tiger sharks prey on albatrosses at seasonal nesting sites, causing other shark species to alter their habitats to avoid predation, revealing complex predator-prey dynamics and the importance of seabird nesting sites in marine ecosystems.
Sharks enter a trance-like state called tonic immobility when flipped upside down, which decreases their sensory responsiveness and pain sensitivity. This behavior is used by scientists for safe research and may serve various evolutionary purposes, though its exact function remains uncertain.
