Background:
Sperm whales are classified as "vulnerable" by multiple conservation authorities. In the Canary Islands, the high density of vessel traffic has made ship strikes the greatest threat to these marine mammals, leading to frequent strandings and vessel-strike-related injuries. Approximately 240 sperm whales inhabit the waters off the Canary Islands, living in pods of 6 to 9 individuals, typically consisting of adult females and juveniles.
Between 2000 and 2018, vessel strikes accounted for 44 of the 81 recorded sperm whale strandings and deaths in the region. This mortality rate exceeds the species' ability to reproduce, posing a significant challenge to population sustainability. Conservation efforts are further hindered by a lack of research into the biology and ecology of sperm whales, leaving critical gaps in understanding their behavior and habitat needs.
Mission:
Researchers from Griffith University and Whales and Climate aim to study sperm whale behavior, including their feeding habits, habitat preferences, social interactions, and overall health. The findings will be shared in a scientific journal to support conservation efforts. The research objectives include:
- Collecting information on sperm whale behavior and physical health, as well as samples like skin or mucus when possible.
- Using tracking tools to gather data on diving depth, swimming speed, movement patterns, and underwater sounds.
- Sharing a media update within 4–6 weeks after the research expedition.
- Publishing summaries of findings on the Whales and Climate website and social media.
- Analyzing and organizing the data within six months of the expedition.
- Submitting a scientific article draft within six months of completing the research.
Research Impacts & Applications:
This research aims to contribute to habitat protection in the Canary Islands by providing data that can support conservation policies and inform legislative action to reduce threats to sperm whales.
