encyclopika:

So, here’s the Master list of ALL of the fish explained posts, with links, common and scientific names, and the “extra” topics we covered, if any. The AC Fish Explained Series went on from April 6th, 2020 to March 2021! The series continued into the Museum Tour in June 2021. The series was started again for “fish past” in November 2021.

snails snails snails snails

I love all my pet snails! These are just some of them! In the first picture is (from right to left) Grizelda, Hazel (above), Patchy (below), and Olive, and in the second picture is Gerald. The first four are mystery snails, a species of freshwater snail, and Gerald is a garden snail.

Gerald in his picture is sporting his horny head lump, which is used by snails to try and attract mates by emitting a scent (apparently). He’s currently trying to woo his tank mate Geraldina but she is completely ignoring him so far

DEPLOY THE BOYS

Insect wings are incredible. Bird wings–while also amazing–seem so simple in comparison. 

The way that earwigs can fold their wings up into such a tiny space is just…perfection.

A hinged shell does not a clam make (QUIZ)

Bivalves are so named for their two hard shell valves made of carbonate, linked by a soft ligament acting as a hinge. They use a strong adductor muscle to close their shell, and the relaxation of the muscle allows the springy ligament to reopen (you might be familiar with adductor muscles as the edible tasty part of a scallop). In deference to the bivalves, laptops and flip-phones are called…

How life was using fossil fuels way before we figured it out.

Humans aren’t the only users of fossil fuels. In many parts of the ocean, natural gas (methane) is constantly bubbling out of the sediment. These areas are known as cold seeps and are often a marker of productive fossil fuel reservoirs in the crust underneath. The name cold seep is somewhat of a misnomer…

When a clam has a stowaway

My mussel contained a tiny half-eaten crab! - Imgur

Source:jeredjeya on Reddit

Bivalves put a lot of energy into their shells. These hardened, hinged sheaths of carbonate are an effective defense against many predators looking to get at the squishy clam’s body encased inside. Parasitic pea crabs have evolved to free-ride on the bivalves’ hard work.

Little hermit crab Pylopagurus discoidalis living in an old ballpoint pen. Notice how its claw is rounded, perfectly shaped to form a protective seal for the round pen opening. This species is normally adapted to live in scaphopod shells, which also are elongated with a circular opening. One of the rare cases where nature can make good use of our plastic waste.

The noble pen shell, Pinna nobilis, largest bivalve of the Mediterranean. They are highly endangered due to overexploitation and destruction of their native seagrass environment. They can grow up to a millimeter each day, making them some of the fastest growing bivalves in the world.

Bat-eared foxes use their enormous ears to hunt for prey which, unlike most foxes, consists mainly of invertebrates. Their hearing is so sensitive, they can even discern insects hidden underground.
