Okay fish fans, let's settle this.

Oh, tell me your favourite fish too! I wanna know ^^

I love butterfly rays because half of the images of them online come in two varieties and it’s

a) a baybey!

b) I know what you are.

Uncharismatic Fact of the Day

You wouldn't think fish need to hold their breath, but that's exactly what hammerhead sharks do when they hunt! Scallopped hammerheads cruise near the surface, where the water is about 15-20°C (59-68°F), but they hunt in much deeper water where the average temperature is about 5–11°C (41-51°F). To conserve their body heat, hammerhead sharks close their gills-- effectively holding their breath for up to 7 minutes before they ascend back to warmer waters.

If you like what I do, consider leaving a tip or buying me a kofi!

Lessiniabatis aenigmatica was a rather strange stingray.

It lived around 50-48 million years ago during the early Eocene, in a shallow warm sea covering what is now Italy, with its three known fossil specimens all coming from the fish-rich Monte Bolca fossil beds.

About 60cm long (~2'), it had a round pancake-like body similar to many modern seafloor-dwelling stingrays – but uniquely it was also almost tailless, with only a tiny, slender, stingless tail.

It wasn't a particularly strong swimmer, instead probably spending most of its time buried in the muddy seafloor sediment. When on the move it likely swam along just above the surface of the seafloor using undulations of its fins, foraging for smaller bottom-dwelling animals like worms, molluscs, crustaceans, and fish.

DYK…

grey reef sharks appear grey from a distance, but actually have a bronze tint to their skin.

grey reef sharks do not pose a threat to humans, but have been inquisitive around divers. if there is food in the water, this shark will become very active and even aggressive. the expected lifespan is estimated to be at least 25 years.

grey reef sharks are less than 1.9 m (6.2 ft) long. the maximum reported length is 2.6 m (8.5 ft) and the maximum reported weight is 33.7 kg (74 lb).

It is once again shark week, my dudes

I'm going to try what I did last year again, so it's time for a new shark with shark facts for every day of Shark Week! Best week of the year :)

Today, it's LEMON SHARKS!

(Negaprion brevirostris)

Lemon sharks are really cool because they're recently learning a lot more about their social behavior! We don't often hear about sharks as social animals, but in the case of lemon sharks, group behavior is very common. Lemon sharks actively *prefer* to be social rather than being alone, see THIS cool behavioral experiment by Guttridge et. al. for more information. They often aggregate in groups based on being a similar size to the other sharks they choose to hang out with!

Baby lemon sharks are frequently found in nurseries in mangrove forests, the tall prop roots of mangrove trees provide shelter and protection for the shark pups as they learn how to, well, be a shark! These animals also return to the same nursery grounds year after year to reproduce, a behavior called natal philopatry! Many animals do this, these sharks are only one example.

Daily fish fact #289

Cartilaginous fish!

The casing that surrounds the eggs of the oviparous species is often called a mermaid's purse, but is more formally known as just an egg capsule or egg casing! They typically only contain one embryo, but there are exceptions; the egg cases of big skates and mottled skates can have up to seven!

the fact that I will never truly know what it’s like to be a shark in a shark cuddle pile is cruel and unusual punishment.

absolutely devastating.

Daily Ray Fact:

The Sixgill Stingray is a heavy-bodied fish. Described only in 1980, it is unique among rays in having six pairs of gill slits rather than five. This ray can grow up to lengths of 5.6 ft and is one of few species that gives live birth, with litters of two to five pups.

Uncharismatic Fact of the Day

Can I offer you a dwarf lanternshark in this trying time? This species of shark is the smallest in the world, at only 20 cm (8 in) long, and is found at depths of 283–439 m (928–1,440 ft). The dwarf lanternshark gets its name for its ability to produce light from a series of f light-producing photophores along its back, which may help it to attract prey or disorient predators.

If you send me proof that you’ve made a donation to UNRWA or another organization benefiting Palestinians, I’ll make art of any animal of your choosing.
