In the warm waters around the Galapagos Islands, a giant oceanic manta ray (Mobula birostris) swoops by, causing the nearby fish to flee due to the large size of the ray. She opens her large mouth to allow zooplankton to be collected and in turn, her gill rakers filter them, allowing seawater to be exhaled.
Here’s something a little different, and not an actual toy, but worth taking a look at anyway. This is a ceramic sturgeon by Wade Ceramics, a pottery manufacturer operating out of Stoke-on-Trent, England. Wade Ceramics got its start in the 1950’s and produced ceramic figurines up until 2018. In 1967 Wade Ceramics entered a partnership with the American Rose Red Tea company who started including Wade figures in their boxes of tea.

Sharks are master hunters. They have inhabited the world’s oceans since the Silurian period and are still standing strong today, even though their population is dwindling due to human greed. They have a basic body plan of a streamlined body, having cartilage rather than bone for their skeletal structure, external gill slits on either sides of the head, and pectoral fins that are not fused to the head.
Sharks are, generally speaking, the living embodiment of efficiency and elegance. Most of this is owed to the sleek, aerodynamic body plan possessed by the majority of shark species, but one shark takes these classic shark attributes to the next level. The blue shark (Prionace glauca) has refined the efficiency and elegance of sharks like no other, with its long, trim, lithe body.

In the warm seas of Australia’s Great Barrier Reef, a small part of the reef got dark as it is obscured by a diamond-shaped shadow, the entity which casted the shadow flaps her wing-like pectoral fins to propel herself through the water as she opens her mouth to feed on krill and zooplankton.

The blog will now take its first look into the epaulette shark species. Epaulette sharks belong to the genus Hemiscyllium, composed of nine formally described species, with one having yet to be described. This genus belongs to the Orectolobiformes order of sharks, commonly described as ‘’carpet sharks’’, which also includes nurse and whale sharks.

The surgeonfish are a group of fish that inhabits warm waters around coral reefs. They are mostly herbivorous and benifit the reefs by eating algae, which balances the coral and algal growth. They range in size from the small bristletooth tang which can get up to 15 cm to the largest surgeonfish species: the white margin unicornfish, which gets to 100 cm in length.
Across the globe, fish populations are under threat as a result of human expansion, altering the environment to suit us. From the Yangtze to the Atlantic, aquatic populations are struggling. This has led to many extinctions, such as the subject of this review: the New Zealand Grayling (Prototroctes oxyrhynchus).

The great white shark (Carcharodon carcharias) is probably the most famous fish on this planet. It has gained a fearsome reputation thanks to movies like Jaws, which portrays these beautiful animals as nothing more that blood-thirsty killers driven by the instinct to kill.

The Zebrasoma tangs are a genus of surgeonfish known for their fins that erect like a sail, a spine at the end of the tail for defense like all other surgeonfishes, and features that make them similar to some butterflyfish species such as a disk shaped body and their long snout.

Pufferfish and their close cousins, the porcupinefish, have a particular defense mechanism of swallowing water and thanks to their expandable stomach, it makes them look bigger, rounder and less appetizing for potential predators (One example in popular media is Mrs Puff puffing up when Spongebob fails his driving test for the X amount of times and going ‘Oh, Spongebob.

Sea anemones paralyze their prey with their stinging tentacles with the aid of little harpoons. However, there are a few animals that use these stinging tentacles to their advantage, mainly to seek refuge from predators. But the most famous of these animals to take advantage of these stinging tentacles: the anemonefish.

When it comes to dangerous sharks to humans, most people will always think about the great white, the tiger, or the bull shark. However, there is a runner up for the most dangerous shark that not many people have heard of, and it’s the oceanic whitetip shark (Carcharhinus longimanus).

Among the various impressive macropredators in the ocean, the tiger shark (Galeocerdo cuvier), is among the most powerful and strangest. The tiger shark belongs to the Carcharhinidae family, often referred to as the “requiem sharks”. The Galeocerdo genus was once diverse, but the tiger shark remains the only extant species within this clade.
