Flashlight Fish Appreciation Post

Anomalopidae (lanterneye fishes or flashlight fishes) are a family of fish distinguished by bioluminescent organs located underneath their eyes, for which they are named.

These light organs contain luminous bacteria and can be "shut off" by the fish using either a dark lid or by being drawn into a pouch. They are used to communicate, attract prey, and evade predators.

These rarely seen fish are nocturnal and found in the Indo-Pacific Ocean and Caribbean Sea.

🐠 Daily Fish Fact: 🐠

Pinnate Batfish adults are normally solitary but will gather in large schools to move over open substrates. The juveniles are mimics of a toxic species of flatworm by colour and shape. They feed on algae as well as jellyfish and other gelatinous zooplankton. This species has been observed to significantly reduce algal growths on coral in studies simulating the effects of overfishing on the Great Barrier Reef.

The second image is of a different species, the largescale four-eyes (Anableps anableps). I included it due to how well it shows the eye, and as a result of far fewer photos available of Anableps dowei. This animal was requested!

Pucker Up for the Sea Lamprey!

The sea lamprey (Petromyzon marinus), also known as the vampire fish, is the most famous member of the order of lampreys, Petromyzontiformes. Despite their similar appearance to eels, lampreys are actually jawless fish, and are more closely related to hagfish than eels. To add further confusion, sea lampreys actually reproduce in freshwater rivers and streams, and are only found in the ocean as adults. They are spread along the Atlantic coasts of North America and Europe, as well as the Mediterranean and Black Sea.

Sea lampreys are the largest member of the lamprey family, at an impressive 30 to 100 cm (11.8 to 39.4 in) long and weighing around 2.5 kg (5.5 lbs). They are generally olive or brownish grey, and their bodies are long and smooth. Perhaps P. marinus' most distinctive feature are their mouths, which are wide and circular with teeth arranged in a circle around the tongue and throat. When opened to attach to its prey, the mouth can stretch larger than the lamprey's head.

Vampire fish are widely known for their feeding habits. Adults are parasites that attach themselves to the sides of fish and feat on their victim's blood and tissue. But despite their fearsome appearance, P. marinus has a variety of predators as both juveniles and adults, including sturgeon, catfish, sea lions, seals, sea birds, and northern pikeminnows. Juveniles are particularly vulnerable, as they are smaller and, as deteriorates, are not equipped with the sharp teeth of adults.

Like many other fish, sea lampreys are anadromous, meaning they migrate from salt to freshwater to reproduce. From April to June, males and females travel up river to find rocky beds in which to build nests. Females lay anywhere from 30,000 and 100,000 eggs in their nest, which are then fertilized by multiple males. After mating, both parents die. The larvae take 3 to 8 days to hatch, and the young spend the next 1 to 3 years filter feeding in their home river. Once they reach maturity, they migrate back to the ocean, where they can reside for up to 5 years before returning to their spawning grounds to complete their lifecycle.

Conservation status: The IUCN has rated the sea lamprey as Least Concern. This species is invasive in the Great Lakes region of the United States. However, within its native range it is threatened by habitat degradation and over-fishing.

can you do the festive snailfish (Liparus marmoratus)?

Today on CHUNK, FUNK, GUNK! We rate

the FESTIVE SNAILFISH:

5/10 Chunk

6/10 Funk

10/10 Gunk

Yet another fish that I hadn’t seen before. Initially I was surprised by their resemblance to the Sea Robin (another silly fishy lad), but after some research I’ve found that the two are extremely different! These goofy little guys are mostly gelatin with soft little bones, that’s pretty chunky. Their bodies are apparently made up of a majority gelatinous substance (that is how they got their name) and secrete a lot of slime and mucous, extreme gunk. Its funk would be higher if it weren’t for how my brain instantly thought it was another fish, which significantly impacted its uniqueness rating. Overall, very good fish. I would like to smooch it on its head if it wouldn’t poison me :)

🐠 Daily Fish Fact: 🐠

Adult Queen Angelfish are selective feeders and primarily eat sponges. Their social structure consists of harems which include one male and up to four females. They live within a territory where the females forage separately and are tended to by the male. Breeding in the species occurs near a full moon.
