Seaside brunch for two

This gull was attempting, with little success, to break the shell of a still-squirming lobster: 

Then it began squawking (what looked and sounded like  a pair bonding call), attracting the attention of another gull. They bobbed their heads and squeaked at each other (as in the linked video), and then the newly arrived one began to attack the lobster:  

 And finally cracked the shell!

Lovely illustrations of tidepool creatures from a book by 19th-century naturalist Philip Henry Gosse:

He also created some gorgeous illustrations of sea anemones.

Phronima

This tiny transparent marine crustacean constructs itself a floating shelter by killing a salp and hollowing out its barrel-shaped body.

Peacock mantis shrimp

This creature is one of the strangest crustaceans in the sea. For one thing, its eyes contain twelve different color receptors (humans have three). For another, this shrimp can snap its claws with force equivalent to a pistol shot, creating a brief burst of light and heat. With an overzealous strike, a mantis shrimp can even break its own aquarium.
