There were XTRATUFS everywhere! Though, a few souls did venture into the tide pools without them. On a foggy and misty Sunday morning, some brave adventurers, sponsored by the Sitka Conservation Society, ventured to Kruzof to learn about intertidal species. The shore was spotted with sea stars and there was quite a bit to learn about this wilderness that presents itself just a few hours every day.
Did you know there are 2,000 species of sea stars?
Not all live here in Southeast Alaska, but this region has the highest amount of diversity of these species.
Sea stars - sometimes referred to as starfish - are not actually fish. They do not have gills, fins, or scales. They pump nutrients through their body with salt water because they do not have blood. They have at least 5 legs, but some have as many as 40!
This is a sunflower sea star. These guys can be up to 3 feet wide and weigh as much as 60 pounds. They feed on clams and crabs and can move pretty quickly through the water. Well, they are no cheetahs, but they get around.
The biggest predators of sea stars are other sea stars. When sea stars feel threatened, they have the ability to shed one of their legs (which they will regrow later) so that a predator might eat that leg and leave them alone.
We hope you enjoyed learning as much as we did!
