أَظْهَرَتْ دِرَاسَةٌ جَدِيدَةٌ أَنَّ حِيتَانَ بَحْرِ الْعَرَبِ الْحَدْبَاءَ تَخْتَلِفُ عَنْ حِيتَانٍ أُخْرَى. وَقَارَنَ الْبَاحِثُونَ مَادَّةَ الْحِيتَانِ الْوِرَاثِيَّةَ مِنْ مُحِيطَاتٍ مُخْتَلِفَةٍ. وَشَمِلَتِ الدِّرَاسَةُ حِيتَانًا تَعِيشُ قُرْبَ سَوَاحِلِ عُمَانَ. وَنُشِرَتْ نَتَائِجُهَا فِي مَجَلَّةٍ عِلْمِيَّةٍ.
وَوَجَدَ الْبَاحِثُونَ أَنَّ هَذِهِ الْحِيتَانَ تَعِيشُ فِي مَجْمُوعَةٍ مُنْفَصِلَةٍ مُنْذُ آلَافِ السِّنِينَ. وَهِيَ تَبْقَى فِي بَحْرِ الْعَرَبِ طُولَ الْعَامِ، وَلَا تَهَاجِرُ كَحِيتَانٍ أُخْرَى. وَتَدْعَمُ النَّتَائِجُ فِكْرَةَ أَنْ تَكُونَ هَذِهِ الْحِيتَانُ نَوْعًا فَرْعِيًّا مُسْتَقِلًّا. لَكِنَّ الْخُبَرَاءَ لَمْ يُقِرُّوا هَذَا التَّصْنِيفَ بَعْدُ. وَيَقُولُ الْبَاحِثُونَ إِنَّ فَهْمَ هَذِهِ الْحِيتَانِ قَدْ يُسَاعِدُ عَلَى حِمَايَتِهَا.

New Study Finds Arabian Sea Humpback Whales Are Distinct
A new study found that Arabian Sea humpback whales differ from other whales. Researchers compared the genetic material of whales from different oceans. The study included whales living near the coast of Oman. Its findings were published in a scientific journal.
The researchers found that these whales have lived as a separate group for thousands of years. They stay in the Arabian Sea all year and do not migrate like other whales. The findings support the idea that these whales may be a separate subspecies. But experts have not yet approved this classification. The researchers say that understanding these whales may help protect them.
