Hydra, SEM
Hydra budding. Coloured scanning electron micrograph (SEM) of a Hydra sp. freshwater hydrozoan. Hydra catch small swimming crustaceans such as daphnia using stinging

Hydroid (Obelia geniculata) Hydranths, gonothecal & a medusa just released

Broad clawed porcelain crab (Porcellana platycheles) covered in a colony of hydroids. Porcelain crabs are decapod (ten legged) crustaceans and not true crabs

Ring-tailed cardinalfish (Apogon aureus) swimming amongst hydroid organisms (green, grey). Photographed in Bali, Indonesia

Hydroid crab on a seasquirt (blue). The hydroid crab (Hyastenus bispinosus) has decorated its body with hydroid (Hydrozoa) polyps

Hydroid crab on a sea pen (Pteroides sp.). The hydroid crab (Porcellanella triloba) has decorated its body with hydroid (Hydrozoa) polyps. Sea pens are colonial organisms related to sea feathers

Hydrozoan colony. Close-up of the tentacled feeding structures of a hydrozoan (Tubularia larynx) colony. Hydrozoa are a type of cnidarian and are related to corals and sea anemones

Nudibranch eating hydrozoa
Nudibranch (Flabellina verrucosa) eating hydrozoa (Eudendrium sp.). Nudibranchs are shell-less marine molluscs that live in seas around the world

Fish eggs. Close-up of fish eggs (white spheres) on a hydrozoan colony (plant-like) with skeleton shrimps (translucent). Hydrozoa are a type of cnidarian that are related to corals and sea anemones

Hydrozoan colony and amphipods. Amphipod (Stenothoe marina) crustaceans sheltering amongst the tentacled feeding structures of a hydrozoan (Tubularia larynx) colony

Hydrozoan (Tubularia indivisa). Hydrozoa are a type of cnidarian and are related to corals and sea anemones

"Exploring the Enigmatic World of Hydroids: A Captivating Journey" Dive into the mesmerizing realm of hydroids, where nature's wonders unfold in captivating forms and movements. From the vibrant Green Hydra (Hydra viridis) gracefully walking through its aquatic habitat to a stunning digital composite showcasing five stages of their enchanting motion, these creatures never cease to amaze. Ernst Haeckel's masterpiece "Kunstformen der Natur" introduces us to Tubuletta Tubulariae, an exquisite hydroid species depicted in Plate 6. Its intricate structure and delicate beauty leave us in awe, reminding us of the endless diversity found within our oceans. Transport yourself back to 1923 with a lithographic illustration capturing a deep-sea underwater scene. Immerse yourself in this mysterious world as you witness fascinating interactions between hydroids and Skeleton shrimp (Caprellidea sp), creating an intriguing ecosystem beneath the waves. Intriguing microscopic images reveal Hydra budding under scanning electron microscopy (SEM). Witness their remarkable ability to reproduce and regenerate, highlighting their resilience and adaptability within their environment. The symbiotic relationship between Common Hermit Crab (Pagurus bernhardus) adults and Hermit Crab Fur Hydroid (Hydractinia echinata) on shells showcases nature's interconnectedness. These tiny organisms find shelter together while forming a harmonious coexistence that fascinates marine enthusiasts worldwide. Journey along the coastlines of Dorset, England, where Candelabrum cocksi emerges from Kimmeridge's depths. Marvel at its ethereal presence as it sways gently with ocean currents—an enchanting sight that reminds us of nature's artistic creations. Observe Obelia geniculata revealing its hydranths, gonothecal structures alongside a recently released medusa—a testament to life cycles unfolding before our eyes. This glimpse into their reproductive process sheds light on the intricate mechanisms that ensure their species' survival.
