Simulation Suggests Basking Sharks Follow Food and Social Cues
A computer model indicates that basking sharks gather at the surface because of both food availability and social attraction.
Updated on Nov. 5, 2026 in Wildlife
Researchers used a computer simulation of 200 virtual sharks to show that basking sharks aggregate due to both food and social attraction. The model mimicked conditions off Ireland's Inishowen Peninsula and was built in partnership with the Irish Basking Shark Study Group and George Mason University.
Why it matters
Basking sharks are usually described as solitary wanderers, so evidence of large surface aggregations raises questions about how they find one another. The findings suggest that environmental changes and ocean noise could affect their social structures.
The model tested four scenarios (food search only, social attraction only, combined food and social, and random movement), with virtual sharks detecting prey within 10 kilometers and other sharks up to 20 kilometers away. The simulation drew on climate and resource data from April to October between 1982 and 2018.

Chelsea Gray is a researcher with the Irish Basking Shark Study Group who led the work on the simulation.
George Mason University
George Mason University is a public research university in Virginia that partnered on the basking shark study.
The details
Researchers from the Irish Basking Shark Study Group, led by Chelsea Gray, partnered with George Mason University to test how basking sharks behave at the surface. They compared each simulated behavioral scenario against real-world observations and found that combined food and social attraction best explained aggregation.
Timeline
Climate and resource data used in the simulation spans April to October between 1982 and 2018.
The findings were published on November 5, 2026.
Wildlife Research Context
The work extends the Irish Basking Shark Study Group's field research on the Inishowen Peninsula into computer modeling of how these solitary animals gather at the surface. It tests whether social signaling, rather than food alone, drives the aggregations that have puzzled researchers studying the species.
The model suggests that noise pollution in the ocean could disrupt basking shark social behavior, which matters to anyone who cares about marine conservation. Protecting quiet coastal waters may be part of keeping these animals' gatherings intact.
The takeaway
Basking sharks may rely on both food and social signals to find each other, which means changes to ocean sound and environmental conditions could affect how they gather. Paying attention to quiet, healthy coastal habitats helps protect these animals.
