# jelly blubber (*Catostylus mosaicus*) The jelly blubber is a soft, jelly-like creature that floats in the ocean. It has a beautiful, colorful body and can be found in warm waters, making it a fascinating sight for ocean explorers! - **Category:** [Invertebrate](https://www.snappit.app/explore/categories/invertebrate) - **Rarity:** Common - **Danger:** 3/5 · Moderate - **Habitat:** Coastal areas ![jelly blubber](https://commons.wikimedia.org/w/index.php?title=Special:Redirect/file/Blue_Blubber_Jellyfish_IMGP2102.JPG&width=800) Photo: Peter Campbell, CC BY-SA 4.0 · [Wikimedia Commons](https://commons.wikimedia.org/wiki/File:Blue_Blubber_Jellyfish_IMGP2102.JPG) ## Appearance The jelly blubber is a sleek marine mammal with smooth, semi-translucent grey skin that glistens like wet jelly. It has a robust, rounded body and a distinctive, bulbous head. Its exceptionally thick, gelatinous blubber gives it a somewhat flexible and fluid appearance underwater. ## Taxonomy - **Kingdom:** Animalia - **Phylum:** Cnidaria - **Class:** Scyphozoa - **Order:** Rhizostomeae - **Family:** Catostylidae - **Genus:** Catostylus ## Interesting facts - Baby jelly blubbers are born live and can swim immediately after birth! - The jelly blubber communicates with squeaks and whistles that travel far underwater! - Their blubber isn't just for warmth; it stores energy for long migrations! - This unique mammal can hold its breath for over an hour during deep dives! ## Special abilities - **Blubber Buoyancy:** jelly blubber has thick, buoyant blubber that helps them float effortlessly and withstand immense pressures in deep ocean dives. - **Echolocation Expertise:** jelly blubber can navigate and locate prey in dark, murky waters using its advanced echolocation system to 'see' with sound. ## Measurements & details - **Length:** 150-300 cm - **Weight:** 100-350 kg - **Lifespan:** 25-40 years - **Speed:** 45 km/h - **Litter Size:** 1 - **Gestation:** 330-380 days ## Diet & Feeding Jelly blubbers hunt fish and squid, using their keen senses to find food in the vast ocean. - **Age differences:** Young jelly blubbers consume their mother's milk before learning to hunt small fish. - **Primary Foods:** sardines, mackerel, squid, krill - **Foraging Method:** Pursuit ## Ecological connections - **Eaten by:** [Orca](https://www.snappit.app/explore/orca) (*Orcinus orca*) — Adult orcas are known to hunt larger marine mammals. - **Hunts:** Atlantic Bluefin Tuna (*Thunnus thynnus*) — Young tuna are a common prey for the jelly blubber. - **Symbiotic with:** Pygmy Sperm Whale (*Kogia breviceps*) — Sometimes found sharing feeding grounds, avoiding competition. - **Depends on:** [Spinner Dolphin](https://www.snappit.app/explore/spinner-dolphin) (*Stenella longirostris*) — Indirectly benefits from shared schooling fish populations. ## Traits - [Solitary](https://www.snappit.app/explore/traits/solitary): Solitary animals live alone for most of their lives, only interacting with others for mating or parental care. - [Camouflaged](https://www.snappit.app/explore/traits/camouflaged): Camouflaged describes organisms that possess coloring or patterns that allow them to blend into their environment. - [Colorful](https://www.snappit.app/explore/traits/colorful): Colorful describes organisms or objects displaying a wide range of bright and distinct colors. - [Filter Feeder](https://www.snappit.app/explore/traits/filter-feeder): Filter feeders obtain nutrients by straining suspended food particles and small organisms from water. - [Herbivorous](https://www.snappit.app/explore/traits/herbivorous): This trait characterizes organisms whose diet consists entirely or primarily of plant material. - [Coastal](https://www.snappit.app/explore/traits/coastal): Coastal habitats are dynamic environments located along the interface between land and sea, influenced by tides, waves, and saltwater. - [Diurnal](https://www.snappit.app/explore/traits/diurnal): Diurnal animals are primarily active during daylight hours, typically resting or sleeping at night. - [Aquatic](https://www.snappit.app/explore/traits/aquatic): Aquatic habitats encompass environments where organisms live predominantly in water, including oceans, rivers, lakes, and wetlands. - [Marine](https://www.snappit.app/explore/traits/marine): Marine habitats encompass all saltwater environments of the Earth's oceans, supporting an immense diversity of aquatic life. - [Glowing](https://www.snappit.app/explore/traits/glowing): Pertaining to organisms that emit light through bioluminescence or fluorescence. ## Collections - [Fish](https://www.snappit.app/explore/collections/fish) ## Safety **Danger:** 3/5 · Moderate Don't touch jelly blubbers; they can sting and make you feel uncomfortable. ## Frequently Asked Questions ### How to identify jelly blubber?
