Fish of the Day

Today's fish of the day is the Alabama Cavefish!

The Alabama Cavefish, scientific name Speoplatyrhinus poulsoni, is known for being one of the rarest troglobitic fish species in North America. Discovered in 1967, by the time the alabama cavefish was scientifically described in 1974, there were only about 100 fish left. On any visit to the cave, only about 10 fish have ever been seen, but they are consistently different fish, so the estimated number is a little under 100, making them critically endangered. This also makes them a possibility for the rarest cavefish in North America!

Despite the large waterways connecting caves in Key Cave National park to several other cave systems, the Alabama cavefish has restricted itself to only one cave for reasons we don't understand. A search of over 120 caves in the surrounding area revealed no populations or signs of populations. With a range consisting only of Key cave in Lauderdale county, Alabama; these fish are constantly faced by the threat of extinction, and most of their worries are based on the limited home range, and waters entering the cave. Any water with chemicals, especially fertilizers and other agricultural runoff are a large concern. That along with competition from more aggressive cavefish, and predation from nearby crawfish. Due to their living situation and delicate population, much is unknown about these fish. But, let us go over what we do know!

The diet of the Alabama cavefish consists mostly of invertebrates found in the caves: copepods, isopods, smaller cavefish, spiders, beetles, and anything else it can find that will fit in its mouth. They grow up to a size of 2-3 inches in length. They have no eyes or pigment, and hunt solely based off of sensory protrusions that dot the head and sides, a trait evolved to handle the almost complete darkness. These fish have no breeding season, and instead breed based off of the environmental signal: when the caves flood in the winter and spring. Insufficient flooding can lead to years where no breeding or spawning occurs, and when it does females carry few eggs, and even fewer eggs hatch. Their lifespans, based off of the lifespan of Northern cavefish, are an estimated 5-10 years.

It was mentioned that Tongrak is willing to support Mahasamut's studies so now I'm sitting here waiting for him to grab that chance so we can officially call him a Marine Biologist

🐢Daily Sea Turtle Fact:🐢

Olive Ridley Sea Turtle: The olive ridley gets its name from the olive green color of its heart-shaped shell. The species is among the smallest of the world’s sea turtles and is found primarily in the tropical regions of the Pacific, Indian, and Atlantic oceans. Similar to Kemp's Ridleys, large groups of turtles gather offshore of nesting beaches. Then, all at once, vast numbers of turtles come ashore and nest in what is known as an "arribada" which means "arrival" in Spanish. During these arribadas, hundreds to thousands of females come ashore to lay their eggs.

Today’s daily ocean fact: moon jellyfish have four stomaches!

The four flower-petal shaped things in the photo below are the jellyfish’s stomaches. Unlike most jellyfish, their stingers are completely harmless to humans. This is why these jellyfish are commonly kept in aquariums!

[Image ID: A photo of a moon jellyfish against a black background. The jellyfish is silvery in colour and mostly translucent. It has four semi-circular stomaches near its center.]

Fish of the Day

Today's fish of the day is the lake sturgeon!

The lake sturgeon, also called the rock sturgeon, and known by scientific name Acipenser fulvescens is one of the best known North American sturgeon species! Found in and around the great lakes, and then across the Mississippi river and Erie canal. Found in 5 differing Canadian provinces and across 24 states stretching from Alabama to Michigan, and as far East as New York. These fish are benthic, spending their time along the bottom of the lake bed, but during spawning these fish will migrate thousands of miles to go back to the stream they were born in.

Like all sturgeon, they are considered living fossils, as sturgeon first appeared in the fossil record upwards of 150 million years ago, with the fish now appearing nearly identical to these ancestors. These fish can get 7 feet or longer, with most being only 4 to 6 feet in length, making them some of the largest sturgeon in North America. Their diet is made up of various invertebrates such as: larvae, small crustaceans, and worms, which they can find along the benthic lake and river beds. The 4 barbels found on these fish have taste buds, which are used to determine what is under their mouth, before they use their prehensile lips to suck up food. When food becomes scarce, these fish are known for migrating for better feeding, which happens semi frequently around the year.

The life cycle of the lake sturgeon is similar to that of most other sturgeons. They begin life as eggs laid in the location their parents were born, in fast paced river streams with lots of flat rocks. The eggs themselves are a bright yellow color, although as the eggs matures this will turn an olive and eventually brown over the course of about 2 weeks. Then they live as larvae only 10mm long, living in and around the dark underside of rocks. After this, as juveniles they will swim to lake environments, where they will spend the majority of their life cycle. These fish can live 55 years long in males and around 150 years for females, with sexual maturity being achieved at an age of around 10 years in males and 30 years in females. Breeding and spawning only happens intermittently every handful of years, and go through around 10 spawning seasons throughout their lifecycle.

For a fun fact to end on for these fish because I'm particularly fond of them, when they reach the stream they will spawn in, these fish are known to porpoise, jumping several feet into the air to end their long journey. That's the lake sturgeon everybody! Have a wonderful day!

Throwback Thursday: Harry Hess and Seafloor Spreading.

This is Harry Hammond Hess. He was the man who came up with an idea to answer Alfred Wegener's Continental Drift question: how did it happen?

He served in the US Navy where he became intrigued by the geology of the seafloor. Essentially, he noticed that the seafloor was shallower in the middle than along the edges. He identified mid-ocean ridges,

and deep ocean trenches.

He said that new crust was made at the mid-ocean ridges as magma oozed up out of the vents and onto the ocean floor. He noted that oceanic crust was youngest near the mid-ocean ridge and older further away. He also noted that both sides of the ridge were symmetrical.

He said that the trenches were where the ocean floor was destroyed and recycled, subsiding beneath the surface and sinking into the mantle to be melted back into magma.

Tune in tomorrow for a look at an animal made famous because it died due to a volcanic eruption of the Yellowstone hotspot. (And tune in next Thursday to learn about some other scientists who aided Henry Hess in his seafloor spreading theory).
