VIDEO: Humpback whale almost swallows kayakers near a CA beach

Two whale watchers had a close encounter while kayaking off the coast of Avila Beach in California, that they will likely never forget.

Video was captured by @AndresJavierNYC on Twitter.

Another Twitter account @GothamWhale warned mariners to be on the lookout for the mammal so they don't accidentally injure it with their boats.

This isn't the first time a whale has taken a swim in the Hudson. Back in 2016, another whale was spotted and hung around in the area for about a week.

Experts say whales are migrating south, but have stopped in our area because of the food supply.

The Parks Department said reasons for the uptick may be because of the improvement in local water quality and an abundance of food sources like Atlantic menhaden.
