Many other species were on the island, including various insects, arthropods, and fish. The abundance of fish and various marine life helped support the massive influx of auklets to the island every year. It was also noted for the presence of an endangered Steller sea lion rookery on the north half of the island. Near-shore benches were carved out of lava flows that could have been dated up to hundreds of years earlier. Approximately 1000 Steller sea lions occupied these rookeries before the 2008 eruption.
