Status: Active — Wild populations recorded
Threat Level: (Severe)
Location of residency: Sewer systems, flooded cave networks, river deltas, coastal estuaries
Encounter Protocol: Avoid all aquatic entry in Crocalpha territory. Armed escort required for sewer or cave traversal. Immediate evacuation if vibrations or surface disturbance detected.
- Species Name: Crocalpha
- Species Code: CRA-077
- Origin: Naturally evolved predator; lineage tied to subterranean and flooded cave ecosystems
- Discovery Date: [READACTED]
- Classification: Apex semi-aquatic predator
- Observed Activity Period: Active at all hours; aggression increases during low-light or poor-visibility conditions **
Large crocodilian-like beast with balanced limbs and an elongated, muscular tail. Broad armored body covered in overlapping plate-like scales. Usually hunched on all fours, though capable of rearing upright.
- Heavy overlapping scales resistant to firearms and able to absorb blast impacts
- Long crocodilian tail for aquatic propulsion and balance
- Forelimbs specialized for grappling prey and tearing obstacles
- Wide-set jaws with immense crushing power, able to deform metal structures
- Juveniles: smaller, lighter-plated, more agile in shallows/tunnels
- Adults: thick armor, extreme bite force, resilient to explosive concussions
- Sensory Detection: Acute vibration detection in water and solid structures; limited underwater vision, relies on tactile sense
- Movement Pattern: Ambush predator from submerged positions; relentless pursuit once prey is engaged until capture or escape outside territory
- Aggression Trigger: Any moving object within territory; highly territorial against its own kind; attacks inanimate objects until recognized as non-prey

Incident C-07-03 — "Maintenance Sweep"
Routine sewer team entered Zone 4 drainage. Contact lost within 3 minutes. Later recovery found shredded drones, tunnel walls scarred, and compressed safety gear with bite force exceeding hydraulic press benchmarks. Remnants washed to downstream outflow. DNA confirmed Crocalpha C-07-B.
- Avoid Crocalpha zones without armored escort vessels
- Deploy seismic sensors to track movement patterns
- Maintain high-voltage deterrent grids at sewer outflows and access points
- No capture attempts permitted except under CRC strategic orders
