What Is a Group of Crocodiles Called?

The most common and widely used term is a bask of crocodiles, describing the animals’ habit of basking together in the sun. Congregation is a more formal alternative, borrowing language usually reserved for large assemblies, used for crocodiles gathered at a shared basking spot or waterhole. Float describes crocodiles resting at the surface of the water rather than on land, drifting with just their eyes and nostrils visible. Nest refers specifically to a mother crocodile and her hatchlings, rather than a general gathering of adults.

Where Did the Name Come From?

Crocodiles aren’t native to the British Isles, so unlike many collective nouns for British wildlife, “bask” didn’t come from the 15th-century Book of Saint Albans hunting tradition. It’s a more straightforward, descriptive term — “bask” simply describes the behavior itself, warming up in the sun, and was applied to crocodiles because that’s exactly what large groups of them are so often seen doing. “Congregation” and “float” are similarly functional, describing where and how the animals are gathered rather than drawing on any older folk tradition.

Crocodile Facts

• Habitat: rivers, lakes, and wetlands across Africa, Asia, the Americas, and Australia; some species, like the saltwater crocodile, also tolerate estuaries and coastal waters.
• Social behavior: crocodiles tolerate close company while basking or during periods of abundant food, but are largely solitary hunters with size-based dominance hierarchies at shared resources.
• Diet: carnivore — fish, birds, and mammals, with larger species like the Nile and saltwater crocodile capable of taking down prey as big as buffalo.
• Lifespan: 70–100 years for large species.
• Strongest bite on record: crocodiles have the strongest bite force ever recorded in a living animal.
• Ancient design: they’ve existed in roughly their current form for around 200 million years.

Example Sentences

• A bask of crocodiles lined the riverbank, motionless in the midday sun.
• A float of crocodiles drifted near the reeds, only their eyes breaking the surface.
• Rangers spotted a congregation of crocodiles at the shrinking waterhole as the dry season wore on.

Other Names for a Group of Crocodiles

Bask remains the term you’ll see most often in nature writing and collective-noun references. Congregation and float describe more specific situations — a shared waterhole and surface-drifting, respectively — while nest is reserved strictly for a mother and her hatchlings rather than any adult gathering.
