Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate 'lemon' as 'лимонный' in the sense of 'flavoured'. It is a colour reference: 'лимонного цвета акула' or the established zoological term 'лимонная акула'.
Common Mistakes
- Writing it as 'lemon-shark' (hyphenated). It is typically written as an open compound: 'lemon shark'. Using it as a metaphor for a 'sour person' is very non-standard and confusing.

Frequently Asked Questions
Lemon sharks are large, powerful predators and are considered potentially dangerous. However, they are not among the most frequently cited species in shark attacks, and many encounters are non-aggressive.
They are found in warm, shallow coastal waters of the Atlantic and Pacific Oceans, particularly around the Americas and western Africa. They are common in places like the Florida Keys and the Bahamas.
Their diet consists mainly of bony fish, crustaceans, rays, and sometimes smaller sharks. They are opportunistic feeders.
No, it is a low-frequency, specialist term. Most people would only use it in specific contexts related to marine life, fishing, or documentaries.
