Those weird little purple velella velella creatures aren’t the only oddity being found on Oregon’s beaches right now. More and more, logs and other debris are showing up covered in mysterious creatures that are paradoxically brightly colored and yet a dark shade of blue.
They are called Pelagic Gooseneck barnacles (Lepas anatifera), and they exist entirely by attaching themselves to other things. In fact, they can’t live without that. If the barnacle in its egg state doesn’t attach itself to anything, it does not live.
The giant mudskipper (Periophthalmodon schlosseri) is a species of mudskipper native to the tropical shores of the eastern Indian Ocean and the western Pacific Ocean where it occurs in marine, brackish and fresh waters. It is most frequently found along muddy shores in estuaries as well as in the tidal zones of rivers. It lives in a burrow in the mud and emerges from the burrow at low tide on sunny days. It can move quickly across a muddy surface and is capable of breathing both in and out of water. The giant mudskipper can grow to a length of 27 centimetres (11 in) TL. This species is of minor importance to local commercial fisheries.
This odd-looking creature has four barbels in front of its mouth, a feature common among bottom-feeders such as catfish, and a protrusible (extendable) mouth.
Sturgeons are opportunistic bottom feeders. Among their food items are mollusks, crustaceans, insects, fishes such as the sand lance that burrow into bottom sediments, and polychaetes. Polychaetes (“many bristles”) are segmented worms with bristles on their paired, leg-like outgrowths called parapodia.
The barbels locate and dredge up food items; the extendable mouth functions much like a vacuum and suitable prey are sucked in. Despite their somewhat ferocious appearance, sturgeons lack teeth.
