"Sea Bunnies" are a type of sea slug called Jorunna parva. Most of them are less than an inch (2.5 centimeters) long and can be found throughout the Indo-Pacific Ocean from South Africa to the central Pacific. Though the most images of these animals show white animals with black spots, these sea slugs are usually yellow or orange.
Bearded Tooth mushrooms (Hericium erinaceus) look nothing like any other mushroom you’ve seen, even if you’ve seen more than a few. This eminently edible mushroom grows on both living and dead trees (usually hardwoods) and when cooked is said to have a seafood-like color and texture.
