Quick Summary

On September 11, Jackie Aguilar encountered a yellow-bellied sea snake while walking along Crystal Cove State Beach in Orange County, California. This highly venomous species hasn’t been seen in the area since the last El Niño period of 2018-2019. Experts warn that warmer water temperatures associated with El Niño could bring these snakes northward from their usual tropical habitat. Marine naturalist Capt. Chad Steffen noted that although the snake is venomous, it poses little threat as it is clumsy and non-aggressive out of water.

Story summary

On September 11, Jackie Aguilar and her family encountered a highly venomous yellow-bellied sea snake while walking along Crystal Cove State Beach in Orange County, California. This is the first reported sighting of this species in the region since 2018, marking an unusual event given the rarity of such snakes so far north. Experts link this occurrence to warming water temperatures associated with El Niño and shifting ocean currents, which may have facilitated the snake's journey into Southern California waters. Although the snake poses a significant threat due to its potent venom, there is no immediate danger if left undisturbed. Researchers are now attempting to independently verify the sighting and assess whether it signifies broader changes in the species' habitat range.
