An educational infographic titled "Matilda's Lab: Map of Chondrichthyes" displays a phylogenetic tree diagram categorizing cartilaginous fish. Concentric, colored circles illustrate taxonomic ranks from species up to class. The diagram is divided into major sections: Holocephali (chimaeras and extinct relatives) and Elasmobranchii (sharks, rays, and skates). Illustrated circular badges feature specific species with their scientific names, including the Megalodon, Great White Shark, Whale Shark, Hammerhead, Manta Ray, and Stingray. These badges are grouped into larger color-coded rings representing families, orders, and cohorts like Batoidea and Selachimorpha.
An educational diagram titled "Map of Chondrichthyes" from Matilda's Lab. The file Chondrichthyes 22.06.26.jpg displays a nested phylogenetic map grouping cartilaginous fish. Concentric colored rings define taxonomic ranks from Species to Domain. The tree splits into major groups: Holocephali (extinct forms, chimaeras) and Elasmobranchii. Elasmobranchii divides into Batoidea (rays and skates like Manta and Torpedo) and Selachimorpha (sharks). Sharks are subdivided into Galeomorphi (including Lamniformes like Megalodon and Great White, and Carcharhiniformes) and Squalomorpha (including Squaliformes and Hexanchiformes). Each animal is illustrated inside a bubble with its scientific species, genus, and family names.
An infographic titled "Map of Chondrichthyes" from Matilda's Lab, utilizing a nested, color-coded Venn diagram structure to illustrate the taxonomy of cartilaginous fish. A key shows rings representing taxonomic ranks from Species to Domain. The main class, Chondrichthyes, is divided into Holocephali (extinct and modern chimaeras like Hydrolagus) and Elasmobranchii. Elasmobranchii is split into Batoidea (rays and skates, including manta and stingrays) and Selachimorpha (sharks). Shark orders feature Galeomorphi (e.g., Carcharhinus glauca, Sphyrna mokarran, Otodus megalodon) and Squalomorphi (e.g., Squalus acanthias). Detailed circular icons show specific species.
Infographic titled "Map of Chondrichthyes" by Matilda’s Lab, illustrating the taxonomic hierarchy of cartilaginous fish through nested, color-coded bubbles. The diagram is split into two primary groups: Holocephali (ghost sharks and chimaeras) on the left, and Elasmobranchii (sharks, rays, and skates) occupying the center and right. The Elasmobranchii section is further divided into: Batoidea: Featuring rays and skates such as the Manta Ray, Blue-spotted Stingray, and Sawfish. Selachimorpha (Sharks): Displaying various orders including the Whale Shark, Great Hammerhead, Thresher Shark, and the extinct Megalodon. A legend in the bottom-left corner explains the color-coding for biological classification levels, ranging from Species (white) and Genus (green) up to Kingdom (blue) and Domain (purple).
A detailed, color-coded taxonomic map titled "Map of Chondrichthyes" by "MATILDA'S LAB". The map uses nested circular rings to show taxonomic hierarchy and is structured into two main, red-bordered sections: "Holocephali" at the top-left and the large "Elasmobranchii" filling most of the space. "Holocephali" includes groups like "Chimaeriformes" (e.g., Hydrolagus colliei) and "Chondrenchelyiformes" (e.g., Menaspis armata). "Elasmobranchii" is divided into major orders. "Batoidea" includes the orders "Rajiformes" and "Pristiformes". The yellow-bordered region "Myliobatiformes" contains families like "Myliobatidae" (Manta alfredi), "Rhinopteridae", and "Dasyatidae" (with Dasyatinae and Neotrygoninae, including Dasyatis americanus). "Selachimorpha" (sharks) has many orders, including "Heterodontiformes", "Orectolobiformes", and "Carcharhiniformes". Notable species are Rhincodon typus and Hemiscyllium ocellatum. The "Squalomorpha" region at the far right includes "Chlamydoselachiformes". At the bottom-right is the pink-framed order "Lamniformes", which includes the extinct "Otodontidae" (Otodus megalodon) and families like "Cetorhinidae" (Cetorhinus maximus), "Alopiidae", and "Lamnidae" (Isurus oxyrinchus). In the center are labels for "Elasmobranchii" and "Chondrichthyes". At the bottom is a nested-ring legend for taxonomic ranks from Species to Domain, and the "MATILDA'S LAB" beaker logo.
A taxonomic infographic by Matilda's Lab titled "Map of Chondrichthyes." It presents a nested, colour-coded visual classification of cartilaginous fish. A key in the upper-right corner defines the taxonomic ranks using nested rings, from Species up to Domain. The main diagram is divided into two primary sub-classes: Holocephali and Elasmobranchii. Within Holocephali, the order Chimaeriformes including ratfish (Hydrolagus colliei). Selachimorpha contains numerous shark orders: Lamniformes: Cetorhinus maximus (Basking Shark). Carcharhiniformes: Carcharhinus glauca (Blue Shark), Sphyrna mokarran (Great Hammerhead), Scyliorhinus canicula (Small-spotted Catshark), Triakis semifasciata (Leopard Shark). Orectolobiformes: Rhincodon typus (Whale Shark), Ginglymostoma cirratum (Nurse Shark). Squalomorpha: Chlamydoselachus anguineus (Frilled Shark). Heterodontiformes: Heterodontus zebra. Batoidea features orders and examples of rays and skates: Myliobatiformes: Manta alfredi (Manta Ray), Taeniura lymma (Blue-spotted Ribbon-tail Ray), Aetomylaeus vespertilio (Reticulate Eagle Ray). Rajiformes: Raja microocellata (Small-eyed Skate). Pristiformes: Rhina ancylostoma (Bowmouth Guitarfish). Plus many more ancient and modern genera, illustrated & housed within taxonomic context, visually demonstrating how species fit into genera, families, and orders. The bottom-right corner features the Matilda's Lab logo.
